pretreatment chemical

Pretreatment mainly involves soaking tank, spray tank, standby tank, circulation system, etc. our professional technicians provide the best design scheme, manufacturing, installation and after-sales one-stop service after inspecting the customer's site, to ensure the cleanness of metal surface and the quality of pretreatment conversion film, so as to provide an excellent precondition for the overall coating quality.

1.No flash point and simple operation, not only did not use chlorine series solvents, also did not use organic solvents are not allowed to use solvents, ozone layer destruction coefficient, greenhouse coefficient is almost zero, is an environmental protection products.Can be directly used in cleaning equipment, and supporting installation of recycling equipment, in order to obtain ISO14000 certification. 2. High cleaning efficiency, and high penetration, micro-hole material can be easily cleaned. 3. Quick drying. 4. The degree of hydrolysis is low, and the causticity of hydrobromic acid is lower than that of chlorinated agent 5. Toxicity information is not under toxicity control in SARA313. Cleaning methods: soak, scrub, ultrasonic cleaning.

1. Free from harmful hexavalent chromium and other harmful substances, it is a green product. 2. Suitable for all kinds of metal and after electroplating treatment, the anti-discoloration effect is good. 3, the formation of anti-discoloration film with hate water and welding function, drying without water stains. 4, after anti-discoloration treatment, the surface is smooth, no hand print. 5. Only produce extremely thin protective film on the surface of the workpiece, which can prevent discoloration economically.
