Product Description:

In the field of metal protection, one kind of material is called as vapor corrosion inhibitors (VCI) that can volatile gases which can slow down metal corrosion under certain conditions through the role of vapor pressure. Dicyclohexylamine nitrite has been the major categories of vapor phase antirust materials with reliable performance, long rust-proof period, and simple operation, easy to use and so on. 

White powder, amine odor, 175 ℃ (decomposition) of melting point, solubility in water at room temperature for 3.9 %, in methanol for 27 %, in 70 % ethanol aqueous solution for 16.7 %. Decomposing when it encountered strong acid and strong alkali. It is also easy to break down in the light and humid environment. Vapor pressure at 25 ℃ is mercury of 0.0002 millimeters. The evaporation rate increased at 75 ℃. 

Application：

There are good inhibition and rust-proof effects to black metal. It can be used for auto parts, decelerating speed chassis, internal combustion engine piston, sleeve, spare parts, machine tools and machine parts, tools, cutting tools, measuring, bearings, seamless steel pipe, machinery parts, textile machines and accessories, knitting machine needles, sewing needle, industry and civil blades, blades, aerospace mechanical, aircraft engines, steel wire, steel plate, steel strip, large-scale storage, packaging buckets, etc. Slowing down corrosion and antirusting to steel, tin, nickel, chromium, aluminum, cast iron; accelerates corrosion to zinc, cadmium, magnesium, copper and its alloys.
