vpci-309 anti-rust powder Yantai treasure agent of US imports

VpCI-307/309 is a suitable sheltered and enclosed space VCI powder metal rust. After VpCI-307/309 gasification, adsorption on all metal surfaces, the protective layer is formed by gas, it can be very effective in preventing corrosion of metal surfaces. VpCI-307/309 has excellent gasification, diffusion and adsorption performance, especially for deep, slender tube, tortuous and difficult to reach cracks and other surface rust. Features · VpCI-307 for carbon steel, rust-proof stainless steel, copper, bronze and aluminum and other metals. · VpCI-309 is suitable for rust-proof steel, stainless steel and other metals. · Apply anti-rust covered and enclosed space metal. * Does not contain silicone, phosphates, nitrites and heavy metals. It does not require surface preparation. · Closed space is opened and then closed, still has a protective function. · Antirust powder easily blown off with compressed air or clean water.
