Области применения

In terms of thermal insulation characteristics, TECHNONICOL polyurethane foams are superior to many analogs. High elasticity, excellent adhesion to the base and good initial expansion make them indispensable insulation materials. Closed cells of insulating foam sealant maintain the desired temperature inside the room and do not allow moisture to pass inside. After curing, very light PU foam material has a high compressive strength, does not shrink or weigh down, and strengthens structures.

The main purpose of polyurethane foams is to fill joints, voids, gaps, cracks with additional functions of thermal and sound insulation. Expanding polyurethane foam allows filling the space between wall panels and cracks wh ere it is impossible to put other insulation. With the help of spray foam insulation, it is possible to create a complete thermal and sound insulation layer on the floor slabs, wall partitions, foundations, and other structures with a complex geometric surface, as well as on utilities. Adhesive PU foam securely binds thermal insulation boards, various panels and other elements.

Как его использовать

Before using PU foams, one should wear gloves and work clothes. It is important to ensure that the foam does not get into the eyes and on the mucous membranes during operation. Single-component PU foam cures with moisture, so the work surface must be pre-moistened with water. The can is shaken, a gun for polyurethane foams is put on and the bottom is turned up when applying the material. Vertical gaps and cracks are filled with foam from the bottom up. In case of use in joints of more than 50×40 mm, it is recommended to apply the polyurethane composition in several layers with each layer moistened. The remaining foam is removed from the tool and the working surface with a foam cleaner.

Full hardening and strength gain occurs within about 24 hours. Polyurethane sealing foam is destroyed by ultraviolet, so it is necessary to protect it after hardening with putty, water-based paint, metal board, etc.
