Product Description
Free Form™ Habitat™ Fire Safe™
Free Form™ Habitat™ Fire Safe™ epoxy putty is a high density epoxy sculpting putty that is flame rated (E84, Class A). Habitat™ Fire Safe™ is solvent-free and contains no VOC’s. Working time is 90 minutes and cure time is 16 hours at room temperature (73° F/23° C). Epoxy cures to a very hard, flame and heat resistant material that is easily painted. Habitat™ Fire Safe™ does not contain any carcinogens (cancer causing agents).
Crystal Clear™ 206
Crystal Clear™ 206 is a water white clear and made specifically for applications that require clarity. 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.
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.
