Activator for priming difficult surfaces such as metal, PVC, EPDM and GRP.
DacoPrep PU Activator allows high adhesion to be achieved with difficult substrates, so that a link is formed between the substrate and the coating on top, forming a chemical anchorage between both elements. Even though DacoPrep PU Activator is a product that by itself it does not offer any film formation or any mechanical properties, it does provides excellent 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. In these instances, DacoPrep PU Activator offers a solution.
