Product Details


121-CF Aluminium Primer

Features:

121-CF Aluminium Primer is a two component epoxy primer utilising state of the art chrome & lead free, complex magnesium anti-corrosive technology designed for use on aluminium structures, plate and extrusions and galvanised substrates.

121-CF Aluminium Primer has excellent adhesion and anti-corrosive when used on aluminium sheet and extrusions, as well as galvanised surfaces.

It is ideally suited as a primer for the topsides of alloy hulls and as a general primer for trailed alloy boats.

Fast dry to recoat and compatability with high performance epoxy and urethane systems makes 121-CF Aluminium Primer the optimum primer for aluminium and galvanising in a wide variety of exposures.

121-CF Aluminium Primer may be intermediate / top coated with:-

  • No.1 Epoxy Primer
  • No.2 Epoxy High Build Surfacer
  • No.3 Epoxy Primer Undercoat
  • No.4 Epoxy Sealer Undercoat
  • Elite® Polyurethane and Elite® 321 Brushing Urethane


Note: 121-CF Aluminium Primer is not suitable for use on surfaces subject to continuous immersion.
