Unlike the TERMOIL line, these products are a line of high-molecular-weight synthetic organic polymers for use in water. They are added as an additive to water to eliminate the vapor phase that forms between the part to be tempered and the water as a cooling vehicle. Using this line of products, great benefits will be obtained such as a uniform and precise tempering, fast austenitic-martensitic transformation, resistance to microbial growth in water, absence of gums and lacquers that affect the process, as well as a high antioxidant power for ferrous metals. The speed of hardening will depend on the concentration added to the water of these products. This line of products is ideal for induction hardening processes.
