Spillage-free adhesive bonding

When 622 2K PU Kleber from Ramsauer is put to work, a tough adhesive joint can be created. That’s what makes this polyurethane adhesive particularly suitable for structural and rigid bonding of corner connections in aluminium windows and on doors. As it is a thixotropic product, the material does not drip. These special properties prevent the work surface from becoming dirty. With its colour and adhesive strength remaining the same even when exposed to UV radiation and strong weather conditions, this reactive adhesive is also an ideal candidate for outdoor use. Once cured, the adhesive seam can be painted over, which is why this material is also suitable for hard jointing of wall panels or touching up joints on GRP sheets. The adhesive is also safe for use in food service use.
