HIGH TACK H785 is a permanently elastic, one-component hybrid adhesive with high density and viscosity, for general construction and industrial applications. Recommended for particularly demanding applications ( for gluing heavy elements or high loads ). Provides instant initial grip without support. For indoor and outdoor use. It is equivalent to products BOSTIK Den Braven Mammoth Glue or SIKA Sikaflex 118 Extreme Grab .
- An ideal adhesive for heavy duty or critical construction and industrial applications, it provides instant grip
- Very good adhesion to most building materials, without priming, including dry and damp, smooth and porous, absorbent and non-absorbent surfaces, vertically and horizontally
- Non-aggressive and chemically neutral (can be used to attach mirrors)
TYPES OF SURFACE
Very good adhesion to most building materials without priming, e.g. concrete, stone, plasterboard, plaster, screed, construction ceramics, clinker, varnished or impregnated wood, MDF, HDF, cork, plywood, chipboard, enameled steel, stainless steel, aluminum zinc, copper, lead, glaze, terracotta, stoneware, glass, glass, mirrors, sanitary ceramics, porcelain, PVC, PU, HPL and similar types of plastics.
The glue is equipped with a special "V" type applicator. When applied according to the recommendations, the adhesive bead has a triangular shape with a base of approx. 9 mm and a height of 9 mm. In this way, from one 290 ml package, you can get about 4.2 m of adhesive track. In the case of gluing flat materials (e.g. cladding, boards, etc.) with strips of approx. 20-25 cm, one 290 ml cartridge is enough for approx. 1 m² of material.
Bonding of heavy or heavily loaded construction materials and various finishing elements, including: finishing strips, frames, thresholds, plinths, furniture joinery (tops, shelves, fronts, recesses), window sills, cornices, linings, insulating materials, mirrors, grilles, enclosures, boards, screens, panels, wainscoting, etc.
The substrate must be clean and degreased. It is recommended to carry out an adhesion test before using on plastic substrates or paint coatings. For highly porous or highly absorbent surfaces, use Bostik Universal Primer T300. After priming wait min. 15 minutes (max. 4 hours) before applying the adhesive.
HOW TO USE
Apply on one side with parallel, vertical stripes at small intervals (10-30 cm - depending on the size and weight of the glued elements). Do not apply on points. Use the factory V-notch applicator supplied with the product. The thickness of the adhesive joint after joining the glued materials is 2-3 mm. Such a distance will ensure optimal bonding conditions, effective ventilation and permanent transfer of deformations.
Without ventilation, the adhesive can only harden on the edges, and in the inner part it will remain uncured for a long time, which will prevent the adhesive joint from achieving the declared mechanical strength. The curing rate of the product depends on the ambient temperature and air humidity. As temperature and humidity levels increase, the polymerization process proceeds faster.
Fresh soiling can be removed with Bostik Universal Cleaner T100. Cured material can only be removed mechanically. Use special Bostik Cleaning Wipes T150 for hand cleaning.
