Unit Size Net Weight Quart Kit 3.6 lb Gallon Kit 12 lb Five Gallon Kit 60 lb Shell Shock FAST and Shell Shock SLOW are thixotropic plastics that self thicken when mixed and can be brushed onto a variety of surfaces or into rubber molds. When Parts A and B are mixed in proper proportion (1A:4B by volume or 1A:5B by weight), material cures at room temperature with virtually no shrinkage to a hard, durable plastic that exhibits good compressive and flexural strength. Fully cured castings are rigid and can be sanded, primed and painted. Color effects are possible by adding SO-Strong Color Tints.Shell Shock plastics are ideal for making fast, lightweight rigid molds for creating silicone appliances and effects (use as a replacement for 'stone molds'). You can also brush a "gel coat" into a rubber mold and back it up with rigid foam, creating a highly detailed lightweight casting. These products can also be brushed onto styrofoam (polystyrol) as an impact resistant coating that can be sanded, primed and painted (minimum 3 coats recommended). Shell Shock plastics can also be used to make rigid support shells for brush on rubber molds.PropertiesTechnical Properties Mix Ratio by Weight 1A:5B Mix Ratio by Volume 1A:4B Pot Life 8 minutes Cure Time 5 hours Color Beige Shore Hardness 85D Mixed Viscosity 3,000 cps Shrinkage 0.0006 in./in.
