SMASH! Plastic™ is a new urethane liquid plastic designed to shatter/crumble on impact (“breakaway glass”). SMASH! Plastic™ is water clear and, once fully cured, shatters like glass. It can be cast solid in thin sections to make window panes or rotationally cast to form hollow bottles, jars or other glass-like objects to be used as breakable props for movie and stage productions. Maximum recommended thickness is 1/8" (0.33 cm.).

WARNING! This product is intended for professional use only.

Features:

  • Room temperature cure system that is easy to use — mixed 1A:1B by volume

  • 90 minute demold time — can be broken after 6 hours

  • Low viscosity ensures easy mixing and pouring

  • Cured castings are UV resistant

  • Vibrant colors and color effects are achieved by adding pigment dispersions

  • Technical bulletin Smash Plastic

Instructions

Selecting A Mold Rubber – Casting into a silicone mold made with Smooth-On Mold Max™ Silicone or Mold Star™ 15, 16 or 30 platinum cured silicone is recommended. Do not use other silicone products as they may inhibit cure.

Preparing – Materials should be stored and used at room temperature 23° C. This product has a limited shelf life and should be used as soon as possible. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.

Measuring & Dispensing – Mix ratio is 100A:100B by weight or by volume (1 cup + 1 cup).

Mixing – Pour Part B into Part A and mix thoroughly for 90 seconds, scraping the sides and bottom of the mixing container several times.

Pouring – For solid castings, pour mixed material into mold cavity. For hollow objects, rotationally cast for 7 to 10 minutes to achieve approximately 0.33 cm wall thickness.

Curing / Demolding – After 90 minutes, plastic is cured enough to be removed from the mold. Material will be hot immediately following cure – let cool before handling. Full brittleness develops over 24 hours.

Surface Enhancement – Applying denatured alcohol via sprayer creates a glossy, glass-like appearance on finished pieces.

Breaking – For breaking against inanimate objects, minimum 6 hour cure is required. For use on people, minimum 16 hours curing and wall thickness not exceeding 0.33 cm.
