CT 1281 C


Product Description

CT 1281 C is an 80% solids synthetic aqueous amine-carboxylate corrosion inhibitor which can be diluted to customize the protection required for ferrous and non-ferrous metalworking operations. CT 1281 C is recommended for applications requiring short-term indoor protection. CT 1281 C is buffered for lower pH ranges, does not contain dicyclohexylamine (DCHA), diethanolamine (DEA) or nitrites and is compounded with raw materials generally considered as safe for greater operator acceptance. CT 1281 C is low foaming and has a break point as low as 1% in pure water when running ASTM 4627-12 cast iron chip test. The product is compounded with a sequestrant to allow prevention of flocculation up to 400 ppm hardness. It is completely soluble in water and may be used as an in-process rust preventative or added to dilutions on synthetic, semi-synthetic, and soluble oil metalworking fluids. CT 1281 C forms a soft, non-tacky near imperceptible film on machine parts for excellent corrosion pro-tection without forming a sticky residue. CT 1281 C can be used for aluminum and zinc, however, should not be used for copper-containing metals such as bronze or brass. CT 1281 C was designed to be used at approximately 75% of the use level of the previous generation CT 1270 C with comparable corrosion inhibition, or used at similar levels for higher performance corrosion protection.
