ABSTRACT:
A molding compound consisting essentially of 0.1 to 10 percent of N-methyl-2-pyrrolidone and a resin selected from the group consisting of epoxy, phenolic and silicone resins. The compound is injected in the mold as in the standard molding process and reacts with any surface contamination that may remain from the previous injection. The contamination is thereby removed with the removal of the molded device and the process is essentially self-cleaning.
