Product Description
Smooth-Cast™ 45D
The Smooth-Cast™ Semi-Rigid line of low-cost semi-rigid urethane casting resins cure quickly to semi-rigid plastics that offer exceptional strength and impact resistance.
New Formulations – New Look!
Smooth-Cast™ 45D is newly reformulated with a translucent white appearance and improved physical properties. All Smooth-Cast semi rigids are now mercury free and phthalate free. These plastics are easy-to-use (mix ratio is 1A:1B by volume) and have low viscosities for minimal bubble entrapment. Vibrant colors are possible by adding SO-Strong™, UVO™ or Ignite™ colorants.
These semi-rigid plastics are good for making impact resistant prototypes, models, toys, props, climbing holds, etc.

EpoxAmite™ HT
EpoxAmite™ HT High Temperature Laminating Epoxy is a water clear, UV resistant laminating epoxy that resists high temperatures up to 300°F / 149°C when properly cured. Pot life is 1 hour and cure time is 24 hours at 73°F / 23°C (post cure required – see post cure schedule). Ultra-low viscosity ensures uniform wetting out and fast penetration of reinforcement materials during hand lay-up or vacuum infusion processes. Cured resin offers superior physical properties.
EpoxAmite™ HT High Temp Laminating Epoxy can be used with S-Glass, E-Glass, Kevlar and carbon fibers for making composite tooling or parts. Applications include making high temperature pre-preg parts, bonding fixtures, vacuum form molds and prototype injection molds.
Use as a backup laminating resin for EpoxAcoat™ HT high temperature surface coat epoxy.
