Triton TWS-PU Primer

TRITON TWS-PU Primer allows both in the case of waterproofing membranes as well as floors, 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. The product by itself does not offer any film formation or any mechanical properties, (not a product to be used on its own), however it does provide extreme adherence in combination with polyurethane single component products.

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, bricks, 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.
