The vac tac 100® hotmelt spray system is used for positioning reinforcement materials and peel ply layers in the mold prior to resin infusion. It is suitable for positioning glass mat, balsa and foams within the composite structure. The vac tac 100® hotmelt glue system is custom made for the construction of yachts and wind turbine blades. This versatile, safe and solvent-free hot melt technology delivers higher levels of tack than is possible with traditional aerosol cans. Once applied, it remains tacky for up to 4 minutes so that core materials can be positioned and adjusted – giving the user more time and flexibility to work. The high levels of tack reduce the amount of adhesive required. This minimizes both the cost, and the risk of impacting the composite structure.

Vac tac 100® hot melt spray adhesives have been specially formulated for use with vacuum infused composites, to position and secure reinforcement fabrics, foams, balsa, peel plies and release films during lay-up – even in the largest vacuum infused composite structures. They only need to be applied to one surface using vac tac 100® spray tools, where, for up to 4 minutes, they provide an instant, very high ‘grab’ adhesive surface. Once attached, the materials can still be easily repositioned if required – offering more working time and flexibility for the user. Only once they have been firmly pushed together is the final adhesive bond made. Unlike VOC (volatile organic compound) spray adhesives, vac tac 100® has an unlimited shelf life and does not require any special packaging, transportation, or storage. When applied correctly, vac tac 100® has none of the health and contamination problems normally associated with airborne particles produced by other adhesives, and is 100 % solvent- and water-free.
