Henkel’s Suncorite 528 is a semi-gloss, chromate free, self-phosphating, protective coating for any surface profile metal, offering a high performance, one process layer with outstanding adhesion and corrosion resistance properties.
Suncorite 528 will easily resist corrosion from salt, humidity, battery acids, fuel oils, solvents and brake fluid. All work to be treated should be free of scale, rust, grease or oil.
It can be spray applied without complete pre-treatment or an energy consuming baking processes – and is widely used in the coating of automotive components such as engine mountings, springs, brake components, metal pressings and virtually all under-body parts. For example, a single 25 micron coating will provide 240 hours ASTM B117 hot salt spray resistance on suitably cleaned mild steel surfaces – this meets stringent automotive specifications.
At 25C Suncorite 528 will be touch dry in approximately 40 minutes, with force drying accelerating hardening.
This product should be stored according to the Highly Flammable Liquids and Liquefield Petroleum Gases Regulations 1972, and providing the container remains unopened, and stored away from extreme temperatures, a storage life of six months can be expected.
