These temperatures and times are presented as a guide only. The curing times are after substrate has been brought up to temperature. The end-user is encouraged to experiment to determine optimum curing schedule.

HANDLING AND STORAGE Prior to using, mix thoroughly to re-suspend fillers. If needed, 125-01A/B-187 can be thinned with small amounts of Creative Materials’ 102-03 thinner. Thinning should be done after mixing parts A and B to maintain proper mixing ratio.
