A superior quality Two-Pack Metal Primer which offers maximum corrosion resistance when used with the appropriate chemical resistant finishes. Suitable for maximum protection on bridges, pylons, industrial buildings etc, especially in coastal regions and damp and humid climatic conditions. The high metallic zinc powder content gives sacrificial protection to blast cleaned steelwork.
Suitable for coating welded areas between joined galvanized sheets and for patching defects in galvanized surfaces, being in effect, brush applied galvanizing.
An excellent primer for shot-blasted steel as a base for Chlorinated Rubber and Epoxy finishing systems. For best results all structural steelwork etc. should be blast cleaned to minimum Swedish standard SA 2½ (blast to white metal).
Characteristics: A Two-Pack Primer based on epoxy resin with a Polyamide curing agent, incorporating a high Metallic Zinc Powder content to confer optimum anti-corrosive and chemical resistant properties.
Advantages: Excellent rust inhibiting properties in damp conditions. Repairs damaged/defective galvanized surfaces. Excellent chemical resistance. Quick-drying. Good adhesion.
Application: Brush, conventional or airless spray.
Thinning & Mixing: Prior to use, mix 6 parts base to 1 part catalyst/curing agent by volume, stirring thoroughly. Can be thinned with Crown Two-Pack Epoxy Thinner if necessary to ease brushing and for spray application. Allow the mixed material to stand for 15 minutes prior to use.
IMPORTANT: As the pot-life of the mixed material is limited. Do not mix more than can be used during the working day.
Drying Times: Surface dry: 1 hour.
Recoatable: 12 hours in dry well-ventilated conditions.
Spreading Capacity: 5-8 m2/l at 40 microns dry film thickness, subject to surface profile and application techniques.
Equipment Cleaner: Crown Two-Pack Epoxy Thinner.
Colour range: Grey.
Pack Sizes: 4 litres (base and catalyst combined).
Availability: Available to order from Crown Depots in Nairobi, Mombasa and Kisumu and through Crown Stockists.
Iron & Steel Structures, Damaged, faulty, galvanized Iron surfaces. Prepare surface (refer datasheet SP 3). Apply liberally by brush 1 coat of Crown two-pack Epoxy Zinc Rich Primer.
1. The Pot-life of the mixture is approximately 24 hours and, therefore, only sufficient material should be mixed to use in one day.
2. The film does not attain maximum hardness and chemical resistance until 4-5 days after application.
