Cure Temperature Test Methods
Cure Temperature Cure Time Test Method
20 to 25°C These data were collected on 50-100 gram samples of a lot believed to be typical and should be used as initial estimates of cure times. Times will vary slightly from batch to batch and can be longer or shorter due to thermal mass of your parts and your heating ramp rate. Pretesting is recommended to confrm adequate cure for your application, For primerless adhesion products, cure time is based on time to reach durometer. Full adhesion may take more time at the cure temperature.
100°C These data were collected on 50-100 gram samples of a lot believed to be typical and should be used as initial estimates of cure times.
