Ritver Epoxy Zinc Phosphate Primer is a high build polyamide cured epoxy primer based on a high molecular weight epoxy resin and zinc phosphate pigment. The product exhibits excellent resistance to c o r ro si o n , mild acids, bases and other chemicals. It has very good adhesion to properly prepared carbon steel and stainless, aluminum and galvanized substrates. [This product is certified by Dubai Central Laboratory following DM-DLCDRD-DP21-2180-(IC) Specific Rules for Low Emitting Materials as per the 2017 Al Sa’fat Dubai Green Building Evaluation System. And following the LEED certificate CREDIT C4.2, as per the rules 1113 for the architectural coating, it has a VOC less water and exempt solvents less than 339 g/l.]

Substrates: As an anticorrosive blast primer for tank exteriors, structural steelwork, chemical plant pipelines, cranes steel structures etc.
Area of Use: Steel and Metal Structures.

A good surface preparation and following the method statement / recommended system procedure of Ritver is an ideal recommendation for the application of Ritver Epoxy Zinc Phosphate 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 2½ 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 Z inc Phosphate Primer before applying the top coat.

For Aluminum:
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 3°C 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. This 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 application.
Caution: Over diluting would result in a sag and run downs

Under dry and cool condition, storage stability can be sound up to 18 months in original sealed containers.
