Transparent Casting Resins

Our CrystalCast products are low viscosity, two component, transparent casting resins. They are used for manufacturing clear statues, colored lighting filters, label doming and glass reproduction. This “non-yellowing” RTV urethane reproduces realistic “glass like” appearance for casting clear or colored parts which require ultraviolet stability. We offer CrystalCast in a variety of hardness and cure times to complement your manufacturing process. The Crystalcast products range from very hard to soft and flexible, see product selection chart below.

CrystalCast requires no preheating or cooking to cast transparent parts. Simply combine the A and B components together in the proper mixing ratio and it will harden into a rigid or flexible clear plastic part. When mixing A and B components together, component B should be thoroughly premixed before combining with component A. Component A requires no pre-mixing. Vacuum degassing is recommended after mixing to remove air bubbles and ensure maximum clarity. For best bubble free results use CrystalCast in a low humidity air-conditioned environment. Pour components together and mix for 1 to 2 minutes using a flat metal spatula (do not use round or square stir rods when hand mixing) never use wood stir sticks. Carefully scrape down sides and bottom of container while mixing to make sure all of component A and component B are thoroughly combined. Mixing containers should be plastic or metal; never use wood or paper as these materials absorb water and will cause moisture bubbles to appear. For high quality glass reproduction we recommend using only platinum cured silicone rubber molds. For clean up use Methyl Ethyl Ketone (M.E.K.), acetone or mineral spirits. Infrared lamps or radiant heat ovens can be used to speed curing of domed labels or thin walled encapsulated parts.

CrystalCast is a nonflammable low odor product and contains no V.O.C. CrystalCast can be tinted with a variety translucent dyes or opaque color pigments. We offer four transparent dye colors, blue, yellow, red and violet. CrystalCast can be pigmented to provide a variety of UV stable colors or used with reflective holographic pigments.

Please refer to the following charts to find the CrystalCast products which best fit your needs.

Do not leave CrystalCast® storage containers open, liquid materials will absorb moisture in the air and later bubble when A and B components are combined. Purge both A and B storage containers with dry gas after each use.
