FEATURES:

USES: Poly 15 Series liquid plastics are useful for production of decorative objects, production parts, tools models, patterns, fixtures, duplicate masters, vacuum forming moulds and general tooling use. Ply 15-5, 15-5X, 15-6, 1510 and 1512 have the feel and density of wood or thermoplastics and Poly 15-3 and 15-3X are more like stone. Poly 15-D65 is a high impact plastic that is well-suited for rotocasting.

MOULD PREPARATION: These products reproduce minute detail from a mould or pattern but may stick or foam when poured on improperly prepared surfaces. A trial casting on a surface finish similar to the final mould should be made, to avoid damaging a valuable mould. Polyethylene and silicone rubber moulds, such as Poly-Sil 71-30, do not require a release agent, but a barrier coat may be helpful. Latex, polyurethane rubber or metal moulds must be dry and require a coat of a suitable release agent, such as Pol-Ease 2300. A good polyurethane mould rubber is any of the Poly 74 Series.

ADDITIVES: Part X and Part F should be stirred into the Part B before adding A. Fillers should be added after A and B are mixed. Part X is a powerful catalyst to increase the speed of curing. A few drops in a one pound mix speeds the cure significantly. Exotherm (heat of reaction) and thus shrinkage on cooling is increased. Experiment to determine the right amount of Part X to use but never use more than 1% Part X of the total weight of the mix or the final physical properties will be affected. Part F can be added to mixed Poly 15-6 and 1510, up to 3% to create foams as low as 6lbs. per cubic foot density. Poly Fibre can be added to thicken the mix to a paste consistency. Poly 15-3X and 15-5X already have Part X added. Microballoons can be added to create a wood-like, lower density material.

MIXING: Prior to mixing, all moulds and equipment must be prepared. Parts A and B should be above 60⁰F. Parts A and B should each be stirred thoroughly prior to use. Over a period of time, sediment may develop on the container bottom. Normally, gently mixing to disperse the sediment prior to use is all that is required. Once the containers of Part A and B are opened, they should be used or resealed tightly as atmospheric moisture contamination may cause foaming of the plastic. Metal or plastic mixing vessels and spatulas should be used to avoid introducing moisture with paper or wood tools. Measure or weigh Pars A and B into a mixing container. Polyethylene buckets are excellent and can often be reused. Mix immediately, thoroughly scraping sides and bottom for one minute. Pour mix into cavity as quickly as possible. If desired, Cab-O-Sil or Poly Fibre should be added after Part A and B are mixed.

CURING: Castings should be allowed to remain in the mould until thoroughly cured. Parts de-moulded too soon may be subject to deformation. Use of pre-warmed moulds will hasten curing. Low temperatures will slow the curing and extend de-mould time.

FINISHING: Cured Poly 15 Series plastics will yellow and chalk when exposed to sunlight and should be painted for exterior use. They can be easily drilled, sanded and machined. If they are to be painted or coated, adhesion of the coating should be checked carefully over a period of time to determine that it is satisfactory for the intended use. If all mould release is removed by detergent washing, most oil paints work well.

CLEAN UP: Tools should be scraped clean before the plastic is hard. Alcohol (shellac thinner), acetone or ME are good cleaning solvents, but are highly flammable. Work surfaces can be waxed or coated with Pol-Ease 2300 Release Agent so hardened resin can be removed.

STORAGE LIFE: At least six months in unopened containers at room temperature. (60-90⁰F).

WARNING: Uncured Poly compounds may cause skin or respiratory irritation or sensitization if improperly handled. Avoid skin and eye contact with the uncured material. If skin contact occurs, remove with waterless hand cleaner or alcohol then soap and water. In case of eye contamination, flood with water and call physician. Use only with adequate ventilation. If there is any doubt about adequacy of ventilation, a mask with air purifying cartridges for organic vapours should be worn when using Part A. Poly Plastics are not to be used where food or prolonged body contact may occur. Poly Plastics burn readily when ignited. Cure should be taken with sanding dust or other easily ignitable forms of these products. Read MSDS and container labels prior to use.

MOULD PREPARATION: EasyFlo ^TM 60 reproduces miniature detail from a mould or pattern but may stick or foam when poured on improperly prepared surfaces. A trial casting on a surface finish similar to the final mould should be made to avoid damage a valuable mould. Polyethylene and silicone rubber moulds, such as the PlatsSil 71 Series, do not require a release agent, but a barrier coat may be helpful. Latex, polyurethane rubber or metal moulds must be dry and require a coat of a suitable release agent, such as Ambersil Poly Release/2. A good polyurethane mould rubber is any of the Poly 74 Series.

ADDITIVES: Part X accelerator and Part F foamer should be stirred into the Part B before adding A. Fillers should be added after A and B are mixed. Part X is a powerful catalyst to increase the speed of curing. A few drops in a one pound mix speeds the cure significantly. Exotherm (heat of reaction) and thus shrinkage on cooling is increased. Experiment to determine the right amount of Part X to use but never use more than 1% Part X of the total weight of the mix or the final physical properties may be affected. Part F can be added to EasyFlo ^TM 60 Part B at levels not to exceed 1% by weight. Microballoons can be added to create a wood-like, lower density material. Bronze powder, calcium carbonate, fly ash, sand, granite or other stone-like fillers can be added as desired. It is imperative that any filler be thoroughly dried before mixing resin.

CURING: Castings should be allowed to remain in the mould until thoroughly cured. Parts demoulded too soon may be subject to deformation. Use of pre-warmed moulds will hasten curing. Low temperatures will slow the curing and extend demould time.

FINISHING: Cured EasyFlo ^TM 60 will yellow slightly and chalk when exposed to sunlight and should be painted or sealed for exterior use. Castings can be drilled, sanded and machined. If they are to be painted or coated, adhesion of the coating should be checked carefully over a period of time to determine that it is satisfactory for the intended use. If all mould release is removed by detergent washing, most oil paints work well.

CLEAN UP: Tools should be scraped clean before the plastic is hard. Alcohol (shellac thinner), acetone or MEK are good cleaning solvents, but are highly flammable. Work surfaces can be waxed or coated with Pol-Ease 2300 Release Agent so hardened resin can be removed.

WARNING: Uncured compounds may cause skin or respiratory irritation or sensitization if improperly handled. Avoid skin and eye contact with the uncured material. If skin contact occurs, remove with waterless hand cleaner or alcohol then soap and water. In case of eye contamination, flood with water and call physician. Use only with adequate ventilation. Small amounts of vapour may be generated during the gelling process. These vapours will safely dissipate in a properly ventilated room. If there is any doubt about adequacy of ventilation, a respirator with air purifying cartridges for organic vapours should be worn. Poly Plastics are not to be used where food or prolonged body contact may occur. Poly Plastics burn readily when ignited. Care should be taken with sanding dust and other easily ignitable forms of these products. Read MSDS and container labels prior to use.

Poly-Optic 1410 is virtually unbreakable and is lower in cost than Poly-Optic 1420, Poly-Optic 1410 can be cured at room temperature and may be post cured at 65⁰C (150⁰F) to improve physical properties.

Poly-Optic 1420 is a tough, high impact resistant system used where polishing rough surfaces and higher heat resistance is necessary. Poly-Optic 1420 must be heat cured between 65-80⁰C (150-180⁰F).

Poly-Optic 14-70 is a firm rubber. Blends of Poly-Optic 1410 and 14-70 allow any hardness between Shore D-85 and Shore A-70.

**Shrinkage is primarily caused by gelling while hot then cooling. Parts that cure with minimal temperature rise will exhibit minimal shrinkage.

USES: Poly-Optic 14 Series clear liquid plastics are useful for production of decorative objects, production parts, tools, models. patterns, fixtures, duplicate masters and general tooling use. Long term exterior use of unfilled, unpigmented systems is not recommended. Casting thick sections over 1/2 to 1 inch thick may result in exothermic heating causing distortion, waviness and significant shrinkage.

MOULD PREPARATION: These products will reproduce minute retail from a mould or pattern but may stick or foam when poured on improperly prepared surfaces. A trial casting on a surface finish similar to the final mould should be made to avoid damaging a valuable mould. Polyethylene and silicone rubber moulds, such as Poly-Sil 70-30, do not require a release agent but condensation type tin catalyzed silicones must be free of residual alcohol which may inhibit surface cure of Poly-Optic resins. Baking for four hours at 212⁰F (100⁰C) prior to use will assure an alcohol free silicone mould. Latex, polyurethane rubber or metal moulds must be dry and require a cost of a suitable release agent, such as Pol-Ease 2300. For optical clarity, highly polished moulds are necessary, such as shine polyethylene or polypropylene.

ADDITIVES: Part 14X is a powerful catalyst to increase the speed of curing for Poly-Optic Resins. Recommended for casting less than 1/2" thick. For best results, mix Pars A and B, degas if required, then add Part 14X and degas again if necessary. On half of one percent speeds the significantly. For example, one half of one percent of Part 14X in a 100 gram mix Poly-Optic 14-10 reduces the pour and curing time by half. Exotherm (head of reaction) and thus shrinkage on cooling, is also increased. Experiment to determine the right amount of Part 14X to use but do not use more than 1% Part 14X of the total weight of the mix or final physical properties will be affected.

MIXING: Prior to mixing, all moulds and equipment must be prepared. parts A and B should be clear liquids above 60⁰F. Once containers of Part A and B are opened, they should be used as soon as possible and resealed tightly as atmospheric moisture contamination may cause foaming of the plastic. Metal or plastic mixing vessels and spatulas should be used to avoid introducing moisture with paper or wood tools. To determine the proper amounts of Parts A and B for Poly-Optic 1410 the following formula has been developed. Total weight of resin required divided by 5 equal one fifth of total mix. One fifth part of total mix times 3 equals the amount of Part A required, and one fifth of total mix times 2 equals the amount of Part B required. Shake or stir Part B before use. Weigh Pars A and B into mixing container. Polyethylene buckets are excellent and can often be reused. Once components are weighted, add Part 14X if desired. Mix immediately, thoroughly scraping sides and bottom, vacuum degas if desired. Pour mix into cavity as quickly as possible. Pressure casting helps produce clear castings. A light spray of Pol-Ease 2300 or quickly passing the flame of a torch over the lack of the casting will help break any bubbles on the back of the pour. For best degassing results, degas Part B separately. After degassing Part B, add Par A and mix both components together, then degas total mix.

CURING: Castings should be allowed to remain in the mould until thoroughly cured. parts demoulded too soon may be subject to deformation. Use of pre-warmed moulds will hasten curing. Low temperatures will slow the curing and extend demould time. Poly-Optic 1410 and 14-70 cure at room temperature. Castings less than 1/2" in thickness use Part 14X or for best results cure 8 hours or more at 140^o - 150^oF. Failure to follow these instructions may result in tacky and/or soft parts. Castings greater than 1/2" thick do not require heat or 14X but the addition or use of either will speed up the curing process considerably. recommended cure for Poly-Optic 1420 in 8 hours at 65^oC (150^oF) and for optimum physical properties 16 hours at 65^oC (150^oF). Poly-Optic 1420 may be demoulded sooner when cured at a higher temperature, such as 30 minutes at 80^oC (180^oF) depending on size of casting and mould. Mould release must be removed from surfaces prior to painting or bonding.

CLEAN UP: Tools should be scraped clean before the plastic is hard. Alcohol (shellac thinner), acetone or MEK are good cleaning solvents, but are highly flammable. Wok surfaces can be waxed or coated with Pol-Ease 2300 so hardened resin can be removed.

STORAGE LIFE: At least 6 months in unopened containers at room temperature (60^o - 90^oF). Poly-Optic 14 Series Part A's may slightly crystallize or become highly viscous during storage. If crystallization has occured warm the container to 40^o - 50^oC (100^o - 120^oF) until crystals dissipate. Cool to room temperature before use.

WARNING: Uncured Poly compounds may cause skin or respiratory irritation or sensitization if improperly handled. Avoid skin and eye contact with the uncured material. If ski contact occurs, remove with waterless hand cleaner or alcohol then soap and water. In case of eye contamination, floo with water and call physician. Use only with adequate ventilation. If there is any doubt about adequacy of ventilation, a mask with air purifying cartridges for organic vapors should be worn when using Part A. Poly Plastics are not to be used when food or prolonged body contact may occur. Poly Plastics burn readily when ignited. Care shoudl be taken with sanding dust and other easily ignitable forms of these productrs. Read MSDS and container labels prior to use.
