VAC-TAC is a new adhesive system from Power Adhesives for securing and positioning reinforcement materials in vacuum infused composites. It has been designed to hold in place typical vacuum processing products such as reinforced fabrics, foam, balsa, bleeders, breathers, peel plies and release fi lms used in even the largest composite material structures, and manufacturers of all sorts of composites will fi nd its many benefi ts appealing. It incorporates the TEC 6300 spray hot melt glue gun, six metres of hose, VAC-TAC adhesive and toolbox/carry case.

The special adhesive is supplied in hot melt cartridge form and the glue-gun is connected to an air and electrical supply. The adhesive is melted inside the glue gun chamber and sprayed directly onto one of the substrates. The materials can be bonded instantly although the adhesive remains tacky for up to 5 minutes if required, allowing for positioning of the substrates.
