Ideal for direct-to-metal coating of auto parts

Waterborne Epoxy Resin and Curing Agent

Industry Background

The global automobile market continues to grow, and the rapid development of new energy vehicle technology has brought huge development opportunities for the automobile manufacturing industry. According to data from Trend Force Consulting, global annual vehicle sales have exceeded 80 million units and are expected to maintain steady growth in the coming years. With the increasing awareness of environmental protection, the automotive industry is actively seeking more environmentally friendly coating solutions. In the field of automotive parts, key components such as drive shafts, shock absorbers, brake discs, brake drums and axles require very high performance of coatings. The coatings required for these components must not only have excellent chemical resistance, but also meet high gloss and high salt spray performance standards for the appearance of the film. Waterborne epoxy coatings show broad application potential due to its environmental protection characteristics and excellent application performance.

Customer Demand

Improved resistance to water and salt spray.
Improve adhesion to different substrates.
Improve the gloss stability of different construction processes.

Polycoat™ Waterborne epoxy resin and waterborne curing agent are developed and manufactured by Lingwe. Polycoat™ has excellent chemical resistance and salt spray resistance, and is suitable for anti-corrosion protection of automotive parts such as axle and drive shaft.

WBH522 waterborne epoxy emulsion and WBH816 waterborne curing agent combination with excellent special substrate adhesion, can be widely used in aluminum substrate, galvanized, stainless steel, hot rolled steel, electrophoretic plate and other metal surface (only need to remove oil, no grinding), providing excellent salt spray resistance and fast drying speed, while cost-effective.

In addition, the combination also has a high gloss, as well as excellent chemical resistance, making it an ideal choice for integrated coating of automotive parts.

Experimental test: high light black paint salt spray

○ Single bottom 60μm film thickness, cold rolled steel grinding.
○ 500 hours salt spray and gloss.
