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. Plasti-Paste® is suitable as a mother mold / support shell material (reinforces shape of rubber mold during casting).
