Cortec: VpCI®-371 coating

Published by

Cortec® VpCIs offer a range of innovative options for reducing manufacturing costs and corrosion.

VpCI®-371 is a high temperature aluminum solvent-borne silicone coating that provides excellent corrosion resistance on metal substrates. It will dry tack free to 5B hardness in about 20 mins. at room temperature and will achieve 9H hardness after heating. The coating is heat stable to 1200°F with prolonged heat resistance from 400-1200°F.

VpCI®-371 was recently chosen by a manufacturer of oil coolers. The company manufactures hundreds of oil coolers for a major producer of heavy equipment. When carbon steel oil coolers had been used inside the heavy equipment, corrosion was found at the six-month preventative maintenance check. As such, the manufacturer had to use more expensive stainless steel to make oil coolers that would resist corrosion. However, the manufacturer wondered if a high-temperature protective coating from Cortec® would allow them to make carbon steel oil coolers that would resist corrosion as well.

To examine the prospect, oil coolers manufactured out of carbon steel were internally coated with VpCI®-371 and sent to the field for testing. At the six-month preventative maintenance check, no corrosion was found on the oil coolers. The heavy equipment customer agreed to specify carbon steel and VpCI®-371 as the materials for making future oil coolers to install in their heavy equipment. This resulted in a significant cost reduction to the oil cooler manufacturer, who was now able to use a cost effective material to create oil coolers that would not corrode.

Cortec’s VpCI®-371 conforms to ASTM D-2485-91: Standard Test Methods for evaluating coatings for High Temperature Service (Method A and B).
