VpCI-369 - Providing superior protection against aggressive environments

Cortec’s VpCI®-369

VpCI®-369 is our best inhibitor for use as an oil additive and/or temporary coating. The protective film is self-healing and moisture-displacing, providing superior protection against aggressive environments. VpCI-369 is also excellent when used as an oil additive for mothballing, shipping, or storage of parts and equipment. In small percentages, VpCI-369 has a minimal effect on viscosities.

VpCI-369 is available prediluted with mineral spirits at the ratio 1:1 as VpCI-369 H, which is recommended for spray can applications.

Fluid hose should be 3/8” I.D. with a length of 10’. A 1⁄4” whip hose may be used for ease of application. Best results will be achieved by using a 0.011”-0.015” tip at 1700 psi (117 bar). The minimum fluid automisation pressure required is 1500 psi (103 bar), which gives 2-4 mils (50-100 microns) WFT/pass.

Product Cleanup: For cleanup of tools and overspray, use alkaline cleaners such as Cortec VpCI-414 or mineral spirits


VpCI-369 can be removed if applied in splash zones, heavy rains, or similar conditions. Parts protected with VpCI-369 should be sheltered for best results.
