How does temperature variation effects epoxy?
– For every 10°F. the temperature falls (when below 77°F) the gel time in the pot will double. The thin film set will come close to a 1.3 increase in time for every 18°F below 77°F. The exact opposite will occur as temperatures increase above 77°F. The gel time in the pot will be cut in half for every 18°F. And the thin film set will decrease by a factor of approximately 0.7 . We have found that the thinner the laminate or the film, the less affected is the thin film set time. Applications which are allowed to cool below the freezing point must be warmed to achieve a full through cure. In the case of freezing, the solid or film must be checked for hardness to ensure full strength has been achieved.
