Details
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.
Instructions for use
The substrates to be bonded must be clean, degreased, dust-free and consistent (load-bearing). Insert the cartridge into the appropriate gun, open it, screw on the nozzle and cut the tip so as to obtain a sufficient opening. The best performances are obtained when using thin film and not thick film, therefore apply Tack PU on one of the two surfaces in spaced beads, distributing it if necessary with a spatula (also toothed). For optimal bonding, 150 g/m2 is required. Glue the two parts before Tack PU threads. The thinner the adhesive layer after compression, the higher its tensile strength. Remove any excess along the perimeter and clean immediately with solvent (or after curing only mechanically) Despite the high viscosity of the adhesive, provide temporary mechanical fixing using clamps to counteract post-expansion and to obtain maximum shear performance During curing, normal ambient humidity must be guaranteed. After approx. 24 hours (at 23 °C) the adhesive will be sufficiently hardened; until then, maintain mechanical fixation.
Tool cleaning
Clean tools in the plastic state of the adhesive with acetone or solvents; after hardening it can be cleaned only mechanically.
Storage
Tack PU must be stored in a dry and cool environment between +5 °C and +30 °C, away from humidity, direct sunlight and heat sources. Under these conditions and in the original sealed packaging, it can be stored at least 12 months.
Warnings
Substrates and structures completely saturated with water prevent adhesion. Due to the wide variety of paints and substrates used in construction and industry, it is recommended to carry out preliminary tests to check adhesion.
Keep out of the reach of children.
Wear protective gloves / clothing and protect eyes / face.
In case of contact with skin, wash immediately with plenty of soap and water.
In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. For more information and in any case before using the product, consult the safety data sheet.

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.
