Product Description
SMASH! Plastic™
SMASH! Plastic™ is a new urethane liquid plastic designed to shatter/crumble on impact ("breakaway glass"). SMASH! Plastic™ is water clear and, once fully cured, shatters like glass. It can be cast solid in thin sections to make window panes or rotationally cast to form hollow bottles, jars or other glass-like objects to be used as breakable props for movie and stage productions. Maximum recommended thickness is 1/8" (0.33 cm.).
CAUTION: NOT FOR HOME USE. THIS PRODUCT IS FOR INDUSTRIAL USE ONLY. With 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.
KX Flex™ 90
KX Flex™ Series urethanes are fast setting flexible urethane casting elastomers that cure quickly and offer exceptional physical and performance properties including high impact resistance. KX Flex™ Series urethanes are easy to color using SO-Strong™, UVO™ or IGNITE™ colorants. KX Flex™ urethanes are phthalate free, mercury free and MOCA free.
KX Flex™ Series urethanes have a pot life of 2.5 minutes and handling time of 30 minutes (depending on mass). With Shore hardness values of 40A, 60A and 90A, this material is used for a variety of applications including fast mold making, fast model duplication, prototyping, durable miniatures, props and special effects, or making parts that are impact resistant. Fully cured castings are flexible, tough and durable.
