Antifreeze And Deicers

Keystone Aniline Corp. offers a variety of dyes that are widely used to color antifreeze and deicers. These dyes have a high degree of solubility in water and glycol systems and can readily be incorporated into the coolant formulation as powders or liquids. These dyes are often used to differentiate coolant products or impart a select color into the formulation.  

Dyes used to color antifreeze products must not only be soluble in the coolant formulation and impart the desired color, but they must also be stable at elevated temperatures, have a reduced amount of salt, and be proven to be non corrosive to any of the engine parts.

Technical Bulletin 3 is available with more information regarding products for antifreezes and deicers upon request.
