Reynolds Plasti-Paste™ EPOXY Trowelable Epoxy Paste
Categories: Polymer; Thermoset; Epoxy

Material Notes: Product Overview: Plasti-Paste™ EPOXY is an epoxy-based version of Smooth-On’s popular urethane Plasti-Paste™ products. It is a two component, fiber-filled epoxy designed for vertical surface application. Part A is a paste and Part B is a liquid. Mix ratio is 2A: 1B by volume or weight. Pot life is 40 minutes and cure time is 16 hours at room temperature depending on mass. Applying heat can reduce cure time. Mixed material holds a vertical surface without sagging and cures very rigid and strong. Plasti-Paste™ EPOXY offers some advantages over urethane Plasti-Paste™ products: 1. Material is not affected by moisture. 2. Material has a longer working time for applying over large areas. 3. Cured material is more rigid with less being required for making support shells/mother molds and 4. Higher heat resistance up (160°F / 71°C). Liquid material can be colored with UVO™ colorants and cured epoxy can be sanded, machined and painted with acrylic enamel paints. This plastic can used as a support shell or mother mold material to reinforce rubber molds during casting. It can also be used for creating themed environments, creating art or special effects. This epoxy is also a powerful adhesive and can be used as a repair material for a variety of industrial applications.
