Introduction - Fast Primer Surfacer Grey/ Red Oxide is based on synthetic modified resin & suitable plasticizer. It contains Zinc Phosphate as anticorrosive pigment. It offers good corrosion
resistance, dries faster. Any type of Top Coat can be applied over this primer coat.
Range of Application - Suitable for application as a priming coat on steel structure, M.S job, pipelines FRP Sheets, & Wood. This can be Top Coated with NC paints, Enamels, Polyurethane and Epoxy paints.
1. It can be used as undercoat for many types of paints.
2. Faster drying than other synthetic primers so immediate over-coating
3. Resists most salts & alkalis & mild acids.
4. Resist to splash of aromatic & aliphatic solvents. (Immersion is not recommended)
5. Good adhesion & scratch hardness. (Compared to normal synthetic primers)
6. Excellent Water & Oil/ Grease Resistance.
|Especially Syn.modified alkyd, plasticizer, & corrosion inhibiting pigments, suitable solvents like aromatic, ethers, & alcohol & ketones.|

Direction for Use/ Application
Remove oil, grease & other contaminations using proper degreasing agents from Ferrous substrate. For heavy corrosive conditions blast clean the surface [for ferrous substrate] For FRP clean the surface with alcohols like iso-propanol etc, Before applying the Primer confirm that no rust particle remains on the surface. Stir the material thoroughly in the container (There may be soft settling on storage condition). Then make the paint suitable for application viscosity by using recommended thinner. Apply by conventional spray or by brush. Take care to close the container immediately after removal of paint to avoid moisture intake & loss of solvents. Do not apply in very humid condition or during the raining, fog, or mist. Also do not apply at very low temperature bellow 10°C Over coating can be possible after 2 - 3 hours interval.
Limitations - This primer has some limitations like poor resistance to strong acids, & higher solvents.
