Acrypol TS PU Primer 20kg

In most circumstances, polyurethane resins, thanks to their chemical cross linking (as opposed to physical curing water-based products), provide excellent adhesion to substrates. However, the very high cohesion of these polymers, may contribute to a lack of adhesion and eventual failure on difficult substrates such as metals or non-porous ceramics.

Some supports tend to offer more resistance to adhesion than others:
Tiles.
Metals
Brick.
Terrazzo.
Marble.
Ceramics.
Old / polished concrete.
Glass.
Stainless Steel.
Old flooring surfaces.

In these circumstances, if it is possible, it is recommended to scratch the surface slightly, creating some friction, and favouring the adhesion and compatibility between materials.


APPLICATIONS
Acrypol TS PU Primer allows both in the case of Waterproofing Membranes as well as in floorings, Adhesives and other polyurethane coatings, to obtain high adhesion links between the substrate and the coating on top, so that there is a chemical anchorage between both elements. Even though Acrypol TS PU Primer is a product that by itself it does not offer any film formation or any mechanical properties, (so it is definitely not a product to be used on its own), it does provide extreme adherence in combination with polyurethane Single component products.
