Special-Primer PP 7560

Special-Primer PP 7560

Special-Primer PP 7560 is an adhesion promoter mainly for untreated polypropylene. Special-Primer PP 7560 may also improve the adhesion on other plastics or different substrates.

Special-Primer PP 7560 is mainly used to solve adhesion problems with critical substrates like polypropylene. With Special-Primer PP 7560 coated plastics can be applicated with e.g. 2 component polyurethane or epoxy systems. In most cases the adhesion promotion of Special-Primer PP 7560 is superior to Special-Primer PP 5130.

Before use Special-Primer PP 7560 must be stirred thoroughly. For application SpecialPrimer PP 7560 must be diluted to 2.5% solids (sometimes even lower) with suitable solvents, e.g. aromatic hydrocarbons.

The primer may be applied by spraying, dipping or printing. It is not necessary to clean the substrate before application; only if the extruded polypropylene is dusted after long storage time.
