Chrome-free high-grade anti-corrosion surface treatment technology suits any environment versatile

 

DISGO® metal finish is a chrome-free high-grade anti-corrosion surface treatment technology which was developed for steel products such as high tensile bolts to prevent delayed fracture due to hydrogen embrittlement. DISGO® metal finish consists of 2 coatings; the zinc-flake rich paint basecoat the iron/steel substrate, and the topcoat containing mainly an organic (epoxy) or non-organic (silicate) resin. The application of processed material is performed by immersion or spraying and then baked in temperatures between 180°C to 300°C.
