JS500 (a water based product) is an improved sealant process which improves the corrosion resistance of most electroplated and mechanically plated deposits.

The Anochrome Group is an approved licensee of JS500, so we can guarantee the correct application and optimum performance for our clients.

When is JS500 required?

MacDermid JS500 is designed to improve the corrosion resistance and coefficient of friction properties on most electroplated and mechanical plated parts. The material is applied following plating as a water based dip coating, which is typically incorporated into the plating lines.

What are the benefits of using this sealant?

Applied over a standard 8um zinc plating, JS500 should achieve or exceed 96 hours to first white corrosion and 500 hours to first red corrosion when tested in neutral salt spray to ASTM B117. This corrosion resistance is maintained even after thermal shock testing.

JS500 contains a UV trace for easy identification of coated parts and can be applied over trivalent-based passivates to give extended corrosion protection. This important factor means that JS500 can be used easily and economically to give high performance corrosion-resistant coatings free from hexavalent chrome.

We understand that a tailored approach to the application of JS500 and other sealing processes is essential to your business.
