Our CrystalCast® products are low viscosity, two component, transparent casting materials. 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.

Application Procedure

CrystalCast® requires no preheating or cooking to manufacture parts. Simply combine the A and B components together in the proper mixing ratio and CrystalCast® will harden into a rigid or flexible 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. Carefully measure component A to component B by weight or volume in separate containers. 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. To prevent moisture contamination of storage containers, purge both component A and component B with Dry-It™ spray gas before re-closing storage containers. (Dry-It™ dry purge spray is available from Industrial Polymers). For CrystalCast® products we recommend a silicone mold release agent Releaser 2257™. For clean up use Methyl Ethyl Ketone (M.E.K.), acetone or mineral spirits.

CrystalCast® 9028, 9030, 9035 & 9040 can be applied by hand or automatic dispensing equipment for manufacturing plastic domed labels. CrystalCast® will coat prepared paper or plastic printed printed labels to form a thick plastic decal. When applying by hand syringe; select a CrystalCast® product, which will allow adequate working time. CrystalCast® 9030 encapsulates electrical components in clear polymer.

Printed labels must be completely dry before applying CrystalCast® to paper surface to prevent moisture bubbles. Label paper should be baked and sealed prior to CrystalCast® application to remove moisture and prevent surface bubbling. It is important to use an appropriate paper when creating domed labels. Coated paper provides best results. Labels printed on laser or bubble jet printers with standard water base inks must be oven dried at 120°F for 1 to 2 hours and coated with clear acrylic spray to prevent moisture bubbling. Labels printed on polycarbonate plastic sheet with solvent base inks will give the best results. 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. Infrared lamps or radiant heat ovens can be used to speed curing of domed labels or encapsulated parts.
