Plasti-Paste EPOXY Five Gallon Kit 60Lbs (801431)
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 (160F / 71C).
Liquid material can be colored with UVO colorants and cured epoxy can be sanded, machined and painted with acrylic enamel paints. This plastic can be used as a support shell or mother mold material to reinforce rubber molds during casting. It can also be used for creating themed environments, art or special effects. Plasti-Paste Epoxy is also a powerful adhesive and can be used as a repair material for a variety of industrial applications. Size: Five Gallon Kit 60Lbs
