We offer an extensive line of dyes for coloring engine coolant/antifreeze. Many colors are available in both powder and liquid forms. Powder dyes are more economical and are the preferred form for export as freight costs are reduced. Liquid dyes offer the convenience of ease of use and can be added directly to the antifreeze/engine coolant. They also are cleaner to use because they do not have the dust issue associated with a powder dye. We have color matches for the most common commercial products.
