Zinc-Aluminium flake solvent base coat technology.
Laurencoat® 565 is a solvent base coating with combinations of zinc and aluminum flakes. The metal particles and reactive resins react on steel base material to form an adhesive bonding. The coating is applied by cold process on to the metal parts by dip spin or spray applications.
During baking a conductive zinc aluminum layer is formed providing sacrificial protection to the steel.
The typical curing temperature for the solvent based products is approx. 230 °C preventing the softening of the hardened steel parts.
The coating is Cr(VI)-free and provides corrosion resistance values from 480 Hs to over 2,000 Hs to base metal corrosion ASTM B 117.
Laurencoat® 565 base coats can be combined with inorganic and organic top coats for highest corrosion protection with multipurpose uses.
