W770 Surfactant. It is a high-quality surfactant for preparing immersing-ultrasonic oil removing, wax removing and cleaning at heated temperature. It is a high-quality surfactant produced by applying foreign polyether surfactants and additives and the latest techniques. It can be used to prepare various high-quality cleaning products like wax solvent,  oil/wax removing powder, degreasing agent and cleaning agent, for oil/wax removing for metal surface with the help of conventional cleaning additives. It has the following advantages:

        High-efficiency--have special effect on cleaning wax and oil dirt on metal surface; powerful capability for removing oil and wax, high efficiency, good durability; effectively protect the metal, keep its luster; especially suitable for oil/wax removing powder;

        Resist to strong alkali and electrolyte solution--normally used in neutral to strong alkali solution and at the temperature scope from 55℃ to 96℃. The optimized using temperature: 80℃±10℃;

        It meets the technical requirements of the production line of immersing and ultrasonic oil/wax removing, degreasing and cleaning for various metals on surfactants.
