Q. What is Actan GS ?
Actan®GS is a VOC-free long-term adhesion primer based on a synthetic resin system in aqueous emulsion at slightly acidic pH.
It shows perfect wet-dry adhesion with any solvent based coating applied on non-ferrous metals such as hot-dip or electro-galvanised steel, aluminium, copper, bronze, stainless steel.
Q. What is the recommended surface preparation ?
Before application of ACTAN™GS, all traces of grease and mineral oil have to be removed from the surface.
Using white spirit or xylene, a simple rinse or wiping with a damp tissue is sufficient.
Any efficient commercial degreaser based on organic solvents or aqueous detergent solutions can be used.
Newly galvanised steel
Partially weathered galvanised steel
Fully weathered galvanised steel
Fully weathered galvanized steel has a completely formed zinc patina.
In this case the only surface preparation needed is a warm power wash to remove loose particles.
Mechanical surface profiling, removal of white rust and clean water rinse are necessary. Chemical surface profiling is an option but rinsing is critical to eliminate all residual acids and contaminants.
Q. How does Actan® GS compare to other adhesion primers ?
Thanks to its unique formulation technology, Actan® GS differs from many other adhesion primers on 13 key points:
