Tack PU is a solvent-free, single-component, polyurethane-based mounting adhesive that cures by reaction with air humidity. To ensure controlled hardening, when gluing non-absorbent materials or materials with less than 8% humidity, it is advisable to slightly moisten the substrates or beads by spraying water (about 10 g water/m² for 150 g adhesive/m²). It does not develop unpleasant odours during application, it does not release acid or basic substances that can corrode metal substrates and it does not affect paints. High viscosity and thixotropy, excellent adhesion on porous and smooth/non-porous substrates, even damp ones, provided they are clean and consistent. The slight increase in volume after application helps to increase the adhesion surface and overall mechanical strength. Once applied to one of the two elements, assembly must be performed before the skin is formed. Once hardened, it guarantees high adhesive strength, high resistance to atmospheric agents, UV rays, impermeability, sandability and paintability.

Tack PU is a single-component, quick-hardening polyurethane adhesive ideal for the tenacious bonding of corner profiles of aluminium frames, doors and metal structures, caulking and other applications where it is required to achieve high adhesive and mechanical performance in a short time. Formulated to perform almost instantaneous bonding of a variety of construction elements in industry, carpentry, construction, joinery, do-it-yourself and wherever chemical, physical and mechanical resistance, ease of use, cleanliness and rapid start-up are required. Thanks to its thixotropy, it is suitable for vertical applications, without dripping, on wood, metal and cementitious substrates.
