GEOCOTE S-860 is chrome-free, inorganic zinc/aluminum flake base coating system for use of corrosion-resistance on fastener and other types of hardware for industries.
It is available with organic top coat such as a lubricant for torque adjustment, a black for color.
As water-based chemistry, GEOCOTE S-860 is environment-friendly product that has no any heavy metal, and it is engineered to be replacement coating system for zinc electroplating.
It is applied via dip/spin application process, and it provides superior performance of corrosion
protection through uniform coating by good workability. |

Application
GEOCOTE S-860 is two package type products of F1 and F2, so it should be applied after agitating the mixture of F1, F2 for at least 12hours.
• Aging condition
While slowly agitating F1 at below 20oC, adding F2 and agitating them for at least 12hours
• Mixture ratio of F1, F2
F1: 9.4 Kg, F2: 10.6 Kg (on the basis of total 20Kg)
• Curing condition
preheat: at least 10 minutes at 180oC
main curing: 30minutes at 330oC
But curing condition should be adjusted according to coater condition and circumstances.
• Coating thickness 10~12Um (Coating thickness can be modified to specific requirement of user) |
