602 is a solvent-based primer that enhances the adhesion of MS Polymer sealants onto porous substrates (especially concrete). It is easy to apply, with good wetting properties and can be used on damp surfaces.
It may be used on various substrates, such as concrete, aluminium, wood, glass and certain plastics as well. It can seal off porous surfaces, improving adhesion of the sealant on to the substrate and prevents the migration of plasticizers to the surface of the substrate.
An initial test on the suitability on a substrate is recommended.
