Smooth-On: Plastic Paste
Plasti-Paste™ is a two-component (Part A and Part B), trowelable plastic that cures quickly. Mixed 1A:3B by volume, Plasti-Paste has no odor and gives end users a 10-minute working time. Handling time is about 90 minutes, with a full cure in 18 hours. The paste can be applied to vertical surfaces (to a thickness of 1/2 inch) without sagging. Once cured, it can be machined, drilled and sanded, and exhibits good abrasion and chemical resistance.
