Smooth-On - Plasti-Paste II Urethane Plastic

New Plasti-Paste™ II is a two component fiber-filled resin that is designed for vertical surface application. This no-odor formulation is an improved version of our original Plasti-Paste™ formula, and the cured product is different in the following ways:

1. Plasti-Paste II is now phthalate free.
2. Cured plastic can be painted (original Plasti Paste™ can not)
3. It is harder, more rigid with better heat resistance.

Part A is a liquid and Part B is a paste. New Mix Ratio is 1A: 2B by volume (62A:100B by weight).Pot life is 10 minutes at room temperature depending on mass. Demold time (can be handled) is about 90 minutes at room temperature depending on mass. Full cure; 24 hours at room temperature. Cure time can be accelerated by applying heat.

Mixed material holds a vertical surface without sagging and cures to a strong, durable and lightweight plastic. Liquid material can be pigmented with So-Strong™ color tints from Smooth-On. This plastic can be used for creating themed environments or special effects, used as a “mother mold” material to reinforce rubber molds and a variety of other applications. This plastic is also a powerful adhesive and can be used as a repair material for a variety of industrial applications. Cured plastic can be sanded, machined and painted with acrylic enamel paints.
