Crystal Clear 202 Resin is water white clear and made specifically for applications that require absolute clarity. Rigid Urethane Casing Resin. Low viscosity ensures easy mixing and pouring. Crystal Clear products cure at room temperature with negligible shrinkage. Cured castings are UV Resistant and are not brittle. Vibrant colors and color effects are achieved by adding SO-Strong color tints. Applications include encapsulation, making prototype models, lenses, sculpture reproductions, decorative cast pieces, jewelry, prototype models, special effects and props. Heat curing is essential to realize full physical properties. Read the Technical Bulletin for full details.
Casting Thickness & Cure Time - The cure time and ultimate shrinkage of Crystal Clear® 202 will vary depending on mass concentration, thickness of the casting, mold configuration, etc. For example, a 200 gram mass of CC 200 will cure faster if left to cure in a conical vessel (cup) versus a casting dispersed as a thin sheet measuring 3 centimeters square by 1 mm thick. This is due to the heat generated by the concentration of material in the cup versus heat that is dissipated from the sheet casting. Castings will resist yellowing when exposed to UV, but may darken over time.
Crystal Clear® 202 is intended for a casting thickness ranging from ½” to 3” at a casting weight maximum of 16 lbs. (7.25 kgs.) Castings greater than 3” should be layer cast.
Safety - 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.
Selecting A Mold Rubber - Pour into a urethane rubber mold (Vytaflex urethane – release agent required), tin cured silicone mold (Mold Max® silicone) or Mold Star® 15, 16 or 30 (not Mold Star® 20T) platinum cured silicone. Do not use other rubber mold products. MOLD STAR is recommended and the most popular.
For Best Results Before Pouring Crystal Clear® Into Mold: Pre-heat rubber mold at 212°F / 100°C for 4 hours. This will minimize chances of fish-eyeing, suck back, corner rounding, large bubbles, etc. in finished casting.
