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.
Plasti-Paste™
Plasti-Paste™ is a two component fiber resin that is designed for vertical surface application. Part A is a liquid and Part B is a paste. Mix ratio is 1A : 3B by volume (41A:100B by weight). It has no odor and pot life is 8 – 10 minutes depending on mass. Demold time (can be handled) is about 90 minutes depending on mass. Plasti-Paste™ holds a vertical surface without sagging and cures to a strong, durable and lightweight plastic. Suitable as a mother mold / support shell (reinforces shape of rubber mold during casting). Can be pigmented with So-Strong™ color tints from Smooth-On. Add Ure-Fil™ 9 as an extender or for special effects.
