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® is ideal for making fast, lightweight rigid molds for creating silicone appliances and effects (use as a replacement for gypsum 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.This product can also be brushed onto foams as an impact resistant coating that can be sanded, primed and painted (minimum 3/8" thickness recommended). Shell Shock® can also be used to make rigid support shells for brush on rubber molds.Shell Shock® FAST working time is 3 minutes. Shell Shock® SLOW working time is 8 minutes.
