Heat-resistant and corrosion-resistant topcoat agent [Achieving energy savings with short-time processing!]
A topcoat agent that shows almost no change in appearance or decrease in corrosion resistance even after heating at 200℃! It can also be processed using the same procedures as general topcoat agents!
The heat-resistant and corrosion-resistant topcoat agent '5K189' is a water-based topcoat agent for zinc plating and zinc alloy plating. By applying treatment on trivalent chromium conversion coatings, excellent corrosion resistance is imparted, and this performance is maintained even after heating. There is almost no change in appearance or decrease in corrosion resistance even after heating at 200°C. A key feature is that it allows for short-time treatment by immersion only, without the need for heating or cooling of the treatment solution, contributing to increased productivity and reduced energy costs. Additionally, due to the immersion treatment, it can be processed with equipment at the same level as post-treatment for plating (no exhaust or explosion-proof equipment required). 【Features】 ■ Excellent corrosion resistance and a glossy appearance are obtained by treating on trivalent chromium conversion coatings. ■ There is minimal change in appearance after heating (up to 200°C), and high corrosion resistance can be maintained. ■ Due to the immersion treatment, it can be processed with equipment at the same level as post-treatment for plating (no exhaust or explosion-proof equipment required). ■ Short-time treatment can be performed by immersion only, without the need for heating or cooling of the treatment solution. *For more details, please refer to the PDF document or feel free to contact us.
