Information
As a “holding” primer to provide protection against corrosion during the fabrication period. A coat of conventional rust inhibiting metal primer should be applied over the Etch Primer, within a one-month period, where severe corrosive conditions, particularly in coastal regions are present or evident.
Substrates: Galvanised steel, stainless steel, hard polished alloys, aluminium, plastic and fibreglass.
Thinner & equipment cleaner: Standard Thinner.
Dilution Ratio: Supplied ready for use – no thinning required. Stir well before use and intermittently during use. Drying Times: Touch dry: 20 minutes. Through dry: <1hr Recoatable: <4hrs.
The product can be applied by: Brush, roller or spray
Spreading Capacity per coat: Depends on film thickness applied, type of texture, surface porosity, imperfections, temperature & wastage during painting 18-20 m2/l when applied by brush or spray on smooth surfaces. 10-12 m2/l when applied to blast cleaned surfaces at 12µm DFT. Maximum spread rate per coat is obtained at minimum dry film thickness and vice versa.
Maximum adhesion on galvanized surfaces, ferrous and non-ferrous metals.
