Cold Temperature Bonding

Strategies for successful application and curing of  WEST SYSTEM epoxy at low temperatures.

The ambient temperature in which an epoxy chemical reaction takes place impacts on the rate of the reaction. Warmer temperatures accelerate the reaction, while cooler temperatures retard the reaction time.  It is the duration of the reaction which, among other variables, will lead to complete or incomplete bonding of the epoxy molecules.  Improperly cured epoxy may possess enough strength to hold the structure together, yet it may fail after being subjected to repeated loading during normal operations.

When using WEST SYSTEM brand epoxy at low temperatures, special precautions can be taken to assure maximum performance.
