Absorption of HCFC-123 and CFC-11 by epoxy motor varnish.

Author(s) : DOERR R. G.

Summary

A study was initiated to determine the effect of various parameters on the absorption of R123 and R11 by epoxy motor varnishes. Absorption of refrigerant continues to increase until equilibrium is established and then remains constant. The rate of attainment of equilibrium absorption is different for each varnish and is more rapid at higher temperatures. The equilibrium absorption value for R123 is linearly dependent on temperature, with greater absorption at lower temperatures. The equilibrium absorption of R11 appears to be relatively independent of temperature. Because of the greater absorption of R123 at lower temperatures, care must be exercised in compatibility studies.
