CR Primer Surfacer Grey & Red Oxide Zink Phosphate
Introduction
CR Primer Surfacer Grey/ Red Oxide is based on Chlorinated Rubber modified resin & suitable plasticizer. It contains Synthetic RedOxide/Titanium dioxide, Zinc Phosphate as anticorrosive pigment. It offers good corrosion resistance, dries faster. It is under coat for Chlorinated Rubber Paint.
Range of Application
Suitable for application as a priming coat on steel structure, M.S job, pipelines & Wood. This can be Top Coated with Chlorinated Rubber paint.
KEY PROPERTIES
1. Faster Drying
2. Resists most salts & alkalis & mild acids.
3. Resist to splash of aromatic & aliphatic solvents. (Immersion is not recommended)
4. Good adhesion & scratch hardness. (Compared to normal synthetic primers)
5. Excellent Water & Oil/ Grease Resistance.

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 Stainless Steel and Aluminum apply Etch primer first. 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 1 hour interval.
