203 Red Primer
Description
Red iron oxide anti-corrosive synthetic alkyd primer.
Recommended Uses
Air drying anti-corrosive primer used on all exterior and interior steel structures in mild corrosive environment.
Features
• Excellent adhesion and filling properties.
• Economical anti-corrosive primer.
Application Instruction
• Method of Application : Brush, roller, or conventional spray.
• Mixing : Stir well before application in order to ensure that a uniform consistency is achieved
• Pot life : 4 hours “if drier 205 is used”
• Thinner / Cleaner : S205 is used for thinning and cleaning. Mixing ratio with thinner depends mainly on temperature and on method of application. For example at 20°C : Brush or roller application will need approx.1.25 liter thinner S205 per gallon and conventional spray will need no more than 1.5 litre thinner S205
• Note : When recoating, a special attention should be given toward drying times

• Number of Coats : 2
• Packaging : 3.6 L in US Gallon or 0.9 L in US Quart
Surface Preparation
Coating performance is, in general, proportional to the degree of surface preparation. Surface must be clean, dry, and free of dust and other contaminants prior to coating.

Steel: Remove all oil, grease, wax…etc from the surface to be coated by thinner S100 or S205. Remove rust and foreign matter using a wire-brush. Then clean the surface with a vacuum cleaner, dry compressed air or a clean brush and wipe the surface by thinner S100 or S205 with a clean cloth.
Painted surfaces: Remove fins, flecks of old paint and other loose material with sandpaper. Roughen glossy areas by sanding then remove dust prior to priming and wipe the surface by thinner S205 with a clean cloth
Drying Time
• Dry to Touch : 30 minutes (ASTM-D1640).
• Dry to Handle : 12 hours “minimum recoat time” (ASTM-D1640).
• Note : Drying times can be affected by many factors such as temperature, ventilation and coat thickness. Higher temperatures will shorten the drying times.
