RomoCoat Two Pack Etch Primer
RomoCoat Two Pack Etch Primer is a two component, self etching primer that chemically bites into metal and gives excellent adhesion on galvanised iron, aluminium and other non ferrous metals, and also improves adhesion/corrosion resistance on steel.
Description
- Two pack air drying etch / wash primer based on special resins and acidic components, designed to etch the metal surface and create a thin, tightly adherent conversion layer.
- Provides strong adhesion for subsequent primers and topcoats, especially on difficult metals where normal primers tend to peel or flake (GI, aluminium, light alloys, pre coated sheets).
Typical applications
Adhesion promotion on non ferrous metals
- Galvanised iron sheets, purlins, guard rails, cable trays, ducts, roofing sheets and metal sprayed steel where adhesion is normally poor.
- Aluminium: panels, doors/windows, cladding, tanks, housings, light alloys and extrusions.
- Other non ferrous: zinc, copper, brass and tin components where a thin etching primer is required before main primer/topcoat.
Adhesion promotion on non ferrous metals
- Bare steel or thin sheet metal that cannot easily be blast cleaned; etch primer plus hand/power tool abrasion gives enough key for subsequent primers/finishes.
- As a first coat in high humidity/monsoon conditions to reduce flash rust and improve adhesion of full paint systems.
