Airtech Advanced Materials Group (Huntington Beach, Calif.) has introduced the Sprayable Multi-Bag Kit to replace the company’s discontinued Brush Bag Kit. The new kit features a spray gun, a regulator, a mixer and 750-ml replaceable cartridge, and is designed to provide a quicker, cleaner way to create a reusable silicone vacuum bag with minimal odor. The material reportedly will cure in thick sections (it is said to cure faster in humid environments) and can be used on large parts, such as boat and automobile components.
