Prevention of Cracking in Polyvinyl Chloride Cables

Electrical cables coated with polyvinyl chloride tend to crack when subjected to heat and oil. Cracking is believed to be due to the loss of plasticizer.

It has now been found that such cracking is prevented by coating the cable with a thin overcoat of polyvinyl acetate. The polyvinyl acetate may be applied from a solvent system, for example, with methylethyl ketone as the solvent. It may be applied by brushing to a thickness of approximately 1 to 3 mils.
