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™ 61D 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.
URE-BOND™ 90 is a two component, slightly expanding urethane adhesive that offers a strong, rigid bond between many different surfaces. It is often used to bond segments of tooling board as well as other porous and non-porous, rigid substrates.
Working time is 8 minutes, handling time is 4 hours and full cure time is 16 hours at room temperature (73°F / 23°C).
