ACTAN®GS is a long-term adhesion primer for use on newly, partially or fully weathered galvanized steel, aluminium, copper, bronze and stainless steel.

It can be sprayed or brushed without further dilution and forms on drying a hard, flexible and non porous film which adheres perfectly to the surface.

ACTAN®GS is an environmentally friendly product for treating galvanized and non ferrous metals prior to the application of a wide range of protective paint systems.


Why ACTAN®GS ?


The usual polyvinyl butyral/phosphoric acid based wash primers and the modified short oil alkyd or epoxy ester primers do not normally ensure the expected adhesion improvement they offer on steel and other non ferrous metals.


The technical reasons for these failures are well known:

  1. Residual acidity in the cured film in the case of wash primers.
  2. Detrimental effect on adhesion of the zinc soaps formed by the presence of free fatty acids in alkyd primers. 


T-wash or mordant solution is unsuitable where partial weathering has occurred.


Sweep blasting can damage irreparably the galvanized layer on vulnerable edges and corners.


ACTAN®GS can be sprayed or brushed without further dilution and forms on drying a hard, flexible and non porous film which adheres perfectly to the surface.



"Actan GS is the ideal solution  for newly galvanised steel as it allows to avoid mechanical and/or chemical profiling."
