Product Description
Smooth-Cast™ 61D
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.

Metalset™ A4
Metalset™ A4 is a powerful epoxy adhesive that has been used for years by all branches of the U.S. Military as well as every major airline and auto manufacturer in the world. Metalset™ A4 is used for hundreds of industrial bonding applications and offers excellent adhesion to porous or non-porous surfaces. It can be applied to vertical surfaces without sagging and cures overnight with negligible shrinking.
Once cured, Metalset™ A4 offers good machining qualities (sanding, drilling, tapping), and resists alkalies, dilute acids and solvents. Applications include stopping leaks in pipes, valves and tanks (i.e. car gas tanks), bonding like and unlike surfaces, filling metal joints, dents, etc., anchoring bolts in wood, concrete, and repairing metal surfaces.
Bell Spec - Metalset A4 meets all quality requirements and can be certified to Bell Spec 299-947-099 Rev. D (see below for details)
