Airtech International Inc. (Huntington Beach, Calif., USA) has introduced the new Multi-Bag (LH) 750 ml Cartridge, used in conjunction with the Airtech Sprayable Multi-Bag Kit (gun with regulator, hi-flow mixer and hi-flow nozzle). This new formulation is designed specifically for use in low humidity (LH) environments and is targeted toward use in the marine, automotive, motor sports and general composites industries. This product features a two-part per measured room temperature vulcanizing elastomer that has been designed for the fabrication of reusable vacuum bags. It reportedly will cure in thick sections and is accelerated by ambient moisture. Multi-Bag is a low-viscosity, self-leveling paste and is designed for use with a reinforcing material RVB Mesh 1, which provides stability, strength and durability.
