SURFASEAL 440 is a chrome- and phosphate-free pre-treatment for aluminium-, steel- and zinc surfaces. It is suitable for soak and spray systems. The conversion coatings generated by SURFASEAL 440 cause a very good adhesion of power- and lacquer-coatings.
SURFASEAL 440 got the approval to QUALICOAT and GSB International as an alternative pre-treatment material for aluminium prior to powder coating.
