For plastics, copolymers, thermo varnished- or powder-coated surfaces and plastic plaster. We recommend pre-tests for difficult adhesions on plastics.
Surfaces must be clean, dry and free of dust and grease. P84 contains solvent which has a cleansing effect. P84 can therefore be used as a cleaner and at the same time as a primer. It is important that always a thin layer of primer remain on the substrate. P84 primer is to be applied with a non-absorbent cloth or absorbent paintbrush (depending on the substrate). The drying time is at least 30 minutes. Within a maximum of 2 hours after application of the primer, the sealant or adhesive has to be applied. After longer drying times it must be checked whether the surface is clean.
