Product Description
Matrix Dryve™
Matrix Dryve™ is a versatile all-powder polymer modified gypsum system that has superior physical and performance properties compared to regular gypsum products. It is an “all-powder” alternative to our original Matrix™ NEO powder/liquid system.
EZ-Spray™ StyroCoat™
StyroCoat™ Plastic is a flame rated (E-84) sprayable polyurethane plastic formulated to economically coat a variety of surfaces. Dispensed through Smooth-On’s EZ~Spray™, Jr. cartridge system, the plastic cures in about 2 seconds and can be applied to vertical surfaces without running off. An advantage of the system is that large areas can be covered in a short period of time. Cured plastic is lightweight, flame, impact, and water resistant. It can be sanded for priming and painting. Plastic can also be sprayed into a rubber mold to make fast, impact resistant castings (application of a release agent may be necessary before spraying into the mold). StyroCoat™ Plastic is used for theme design / fabrication applications, making movie set environments, making surfaces water resistant and other industrial applications.
