XTREME HIGH TACK - Extremely High Initial Tack MSP Adhesive

Xtreme High Tack is a high performance professional adhesive based on MSP (Modified-Silyl Polymer) technology. It has an extremely high initial tack, which cures under influence of humidity to form a durable elastic rubber.

Recommended Uses

Developed as a universal adhesive for bonding many building materials, High Tack can be used on stone and concrete, mirrors and glass, plasterboard, PVC, hard plastics, enamel and ceramics, copper/lead/zinc/tin, aluminium (including COLORBOND® and ALUCOBOND®), fibre cement panels, and wood.

It is ideal for bonding where high early strength is desired to reduce the necessity of mechanical fixing and support through the use of nails, screws and bracing.
