Chemical Resistance

PLEXINATE P100 vs. DERAKANE 411

A number of discs of 35 gram weights were prepared from Plexinate P100 and Derakane 411. They were then cured in accordance with manufacturers recommendations and then post cured. the uncured surfaces were removed.

The discs were immersed in the various solutions below and the weight gains recorded after 72 hours. The solvents/solutions were periodically heated to the temperatures stated.
