Greenkote®

GREENKOTE® coatings increase the protection of automotive components, construction and infrastructure elements, electric and electronics and many others. The coatings increase resistance to low- and high-temperature corrosion, improve wear resistance and promote better bonding of steel to rubbers and plastics. Since they contain no environmentally-harmful substances, GREENKOTE® coatings are in full compliance with the EU End of Life Vehicles (ELV) Directive (2000/53EC), ROHS and WEEE.

TPCT – Thin Powder Color Topcoat group:

A dry powder painting process for all types of parts with or without our base coatings, applied in bulk, compared to hanged sprayed and baked with substantial cost savings. This new powder topcoat manufactured by powder organic and in-organic materials, is a new family of products called ‘TPCT’ (Thin Powder Color Topcoat). The major advantages of this top coat are:

  • is a more economical and clean process than conventional wet coating processes 
  • components may be coated to whatever the color requirements the customer may require.
  • potential cost savings!
