Powder Coating Services

Powdertech Powerblast

A process to roughen the surface of mild steel prior to powder coating or galvanizing using a range of abrasive media. Powerblast uses steel grit to achieve a surface profile of SA 2½ on steel substrates, ISO 14920 and ISO 14921.

  • Grit blasting , zinc powder priming and top coat all controlled by Powdertech
  • Enables fabrication without traditional drainage holes required by hot-dip galvanizing.
  • Increases adhesion of powder primers and colour coats
  • Increases design possibilities for complex fabrications
  • Reduces some surface defects in base material
  • Cleans rusty or pre-painted material to reveal ‘new’ base metal
  • Used before galvanizing to increase the thickness of zinc.

TYPICAL APPLICATIONS

External: In conjunction with epoxy zinc primer powders for general un-galvanized architectural steelwork.

Internal: Removal of mill scale from hot rolled steel. Increasing of adhesion.
