Surface Treatment for Low Density and Porous SMC

We have taken the interface phenomenon developed with the use of an acrylic mist-coat identified by Dr. G. Dale Cheevers, General Motors Research Staff, a step further by developing a readily-processible sealer system for standard and low-density SMC. In this development, the standard practice required in a molder’s paint operations was observed, and results were both predictable and repeatable.
