General product information

Ritver Epoxy Primer is a High build top coat based on a high molecular weight epoxy resin and zinc phosphate pigment and forms a two component primer with a suitable virtue of the epoxy resin it has excellent resistance to mild acids, bases and other chemicals. It achieves good build up in one single has outstanding anti-corrosive properties and has a good abrasion resistance

A good surface preparation and following the method statement / recommended system procedure of Ritver is an ideal recommendation for the application of Ritver Epoxy Primer.

For Metals:

In case of mild conditions of application, remove the previous coat with a mechanical tool, wire mesh, or a mild sweep blast is to be done.

In case of detailed Surface preparation is warranted, remove all wax, oil and grease should be removed by solvent cleaning in accordance with the guidelines given by SSPC-SP1. Where necessary remove weld spatter and round off all rough weld seams and sharp edges to a smooth surface. Ideally abrasive blast clean to a minimum standard of Sa 2- Swedish Standard
SIS 05 59 00 or ISO 8501-1:1988. Any surface defects revealed by blast cleaning should be ground, filled or treated in a suitable manner. After blasting, remove dust from the surface. The surface to be coated must be clean and dry with Ritver Epoxy Primer before applying the top coat
For Aluminium: Degrease and abrade with Ritver Epoxy Thinner and wet-or-dry paper. Apply Ritver Etch Primer. Immediately follow with the top coat.

Exclusions for successful application include perpetually wet surfaces and also large cavities on metal surfaces.



Adequate ventilation is an ideal situation as it helps in drying and the good application itself. Avoid high humid conditions i.e., 95% when condensation is likely to interfere and also when the surface temperature is at least 3c above dew point.

Application:
A normal brush or a roller may be used for difficult shapes or touchup; however, additional coats may be required to achieve the recommended film thickness. The method of application is recommended for stripe coating welds, edges, rivets etc.
To be done by Airless spray 1800-2300 psi. Nozzle size: 0.015-0.019 inches or conventional spray at 50 60 psi. It can even be done with a roller.
It is generally recommended to give a mist coat followed by a full coat.

One can add Ritver Epoxy thinner for achieving spray viscosity of app 17 18 secs on Ford cup 4 ASTM at 30 C and for ease of ion: Over diluting would result in a sag and run downs.
