What is JS500?

JS500 is a sealant which is used in conjunction with zinc electroplating as part of a finishing process. The water-based sealant is used in the electroplating process to strengthen the corrosion resistance of the components. Additionally, it can help to improve their coefficient of friction. JS500 is an environmentally friendly coating, and often applied over zinc plated components and surfaces with trivalent passivate. As this does not contain hexavalent chromium, the result is a protective coating that is compliant with Rohs and ELV.

JS500 is in fact the trade name for one of the most common types of these sealants. Although there are plenty of other manufacturers, JS500 is one of the most widely used brands worldwide and has been specified in many OEMs specifications for zinc plating.

The Benefits of JS500 Zinc Plating

When used in conjunction with zinc plating, JS500 can significantly enhance the corrosion resistance of a component. For example, after applying a JS500 coating to a zinc passivated part, we can usually turn 120 hours of corrosion resistance into 400 hours. With this in mind, it is easy to see why so many manufacturers specify a JS500 treatment as it is a highly cost effective solution for optimising corrosion resistance.

JS500 also provides increased protection against wear and abrasion when compared with a component that has only undergone a zinc electroplating treatment. As the sealant also contains a UV trace, components coated with this sealant are also easily traceable.

Industries and Applications

JS500 is commonly used in the automotive industry for zinc electroplated components. Plenty of major automotive manufacturers have approved the sealant including General Motors and Ford.

Alongside automotive components, the silica based product can also support fastener industries. As it is silica based, here at EC Williams, we can add it to built in lubricants, and it will impregnate into the passivate. So, if you are looking for a relatively high level of corrosion resistance for your robot assemblies or other mechanical components, JS500 could be the perfect addition to the lubricant.
