These rigid urethane casting resins differ only in working and demold times. Low viscosity ensures easy mixing and pouring. Crystal Clear™ resins cure at room temperature with negligible shrinkage.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cp\u003eCured castings are:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUV Resistant\u003c\/li\u003e\n\u003cli\u003eNot brittle\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eVibrant colors and color effects are achieved by adding pigment dispersions.\u003c\/p\u003e\n\u003cp\u003eApplications include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEncapsulation\u003c\/li\u003e\n\u003cli\u003eMaking prototype models\u003c\/li\u003e\n\u003cli\u003eLenses\u003c\/li\u003e\n\u003cli\u003eSculpture reproductions\u003c\/li\u003e\n\u003cli\u003eDecorative cast pieces\u003c\/li\u003e\n\u003cli\u003eJewelry\u003c\/li\u003e\n\u003cli\u003ePrototype models\u003c\/li\u003e\n\u003cli\u003eSpecial effects\u003c\/li\u003e\n\u003cli\u003eProps\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstructions\u003c\/h3\u003e\n\u003cp\u003eSafety – Store and use at room temperature (73°F \/ 23°C). These products have a limited shelf life and should be used as soon as possible. Environmental humidity should be as low as possible. Good room size ventilation is essential. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Wearing a NIOSH approved respirator will minimize inhalation of residual fumes. Use in a low humidity environment (below 50% RH). Mixing containers should have straight sides and a flat bottom. Mixing sticks should be flat and stiff with defined edges for scraping the sides and bottom of your mixing container.\u003c\/p\u003e\n\u003cp\u003eSelecting A Mold Rubber – Pour into a urethane rubber mold (Vytaflex™ urethane or Brush-On™ series urethane – release agent required), tin cured silicone mold such as Mold Max™ 20, 25, 30 or Mold Max™ STROKE (not Mold Max™ ‘T’ Series), or Mold Star™ 15, 16 or 30 platinum cured silicone (not Mold Star™ ‘T’ Series). Do not use other rubber mold products.\u003c\/p\u003e\n\u003cp\u003eIf using Mold Max™ silicone, to prevent cure inhibition, post-cure newly cured silicone mold for 8 hours at 150°F \/ 60°C and let cool prior to casting resin. If you are unsure about surface compatibility, a small scale trial casting should be made.\u003c\/p\u003e\n\u003cp\u003eFor Best Results Before Pouring Crystal Clear™ Into Mold: Pre-heat rubber mold at 212°F \/ 100°C for 4 hours. This minimizes chances of fish-eyeing, suck back, corner rounding, and large bubbles.\u003c\/p\u003e\n\u003cp\u003eCasting Thickness \u0026amp; Cure Time – The cure time and ultimate shrinkage will vary depending on mass concentration, casting thickness, and mold configuration. Castings resist UV yellowing but may darken over time.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCrystal Clear™ 200: ½” to 3” thickness, maximum 16 lbs.

Use clean metal or plastic containers. Materials should be stored and used at 73°F \/ 23°C. Stir or shake Part B thoroughly before dispensing.\u003c\/p\u003e\n\u003cp\u003eMeasuring – Mixing ratio is 100A:90B by weight. Use an accurate digital gram scale. Do not measure by volume.\u003c\/p\u003e\n\u003cp\u003eMixing – Mix slowly but thoroughly for at least 90 seconds. Scrape sides and bottom of container frequently. Add pigment or filler to Part B before combining with Part A.\u003c\/p\u003e\n\u003cp\u003eVacuum degassing greatly reduces bubbles. Pump must pull a minimum of 29 inches of mercury (1 bar). Vacuum until material rises, collapses, then hold for one additional minute.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003ePOURING, CURING \u0026amp; PERFORMANCE\u003c\/p\u003e\n\u003cp\u003ePouring – Pour material in a single spot at the lowest point of the mold. Do not pour directly over encapsulated objects. Allow material to seek its level to minimize air entrapment.\u003c\/p\u003e\n\u003cp\u003eFor best results, use pressure casting at 60 PSI for the full cure time.\u003c\/p\u003e\n\u003cp\u003eCastings will reach full physical properties in 7 days at room temperature. Early demolding may cause surface tackiness, removable by heating at 150°F \/ 65°C for 6 hours.\u003c\/p\u003e\n\u003cp\u003ePost Curing – Post curing improves heat resistance and UV performance. After full room-temperature cure, heat for 6 hours at 150°F–160°F (65°C–72°C). Allow casting to cool before demolding.\u003c\/p\u003e\n\u003cp\u003eBecause no two applications are quite the same, a small test application is recommended to determine suitability.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eCAUTION: NOT FOR HOME USE. THIS PRODUCT IS FOR INDUSTRIAL USE ONLY. \u003c\/strong\u003eWith adequate local exhaust ventilation, respiratory protection is not normally required when using this product. Where risk assessment shows air-purifying respirators are appropriate, follow OSHA respirator regulations and European Standards EN 141, 143 and 371. Protective clothing (gloves and long sleeves) is required to minimize the risk of dermal sensitization. If breathing is affected or a dermal rash develops, immediately cease using this product and seek medical attention. Read SDS before using.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003eIMPORTANT: Shelf life is reduced after opening. Use remaining product as soon as possible.
