Low Friction Coating of EPDM Gaskets
(click on thumbnail to enlarge)
A customer in the drain pipe industry approached Alpha Coatings to apply a low friction coating on EPDM rubber gaskets to allow for easier assembly of drain pipes. Previously, the customer was applying a grease coating on the gaskets by hand, contributing to higher labor costs and environmental concerns. First we pre-heated the EPDM gaskets and then sprayed them with a clear, low friction Resilon coating. A reciprocating coating process was used for smaller gaskets and a bulk footage coating process for larger gaskets. After curing the gaskets in an oven, we packaged the product in boxes and applied labels indicating the quantity. With a length up to 60" and a width up to 1.5", the gaskets had a coating thickness of .4 to .6 mils, and met tolerances of .2 mils. After performing extensive cure testing and dry film thickness (DFT) testing, we delivered the product to the customer in Hamilton, Ohio.
