PlatSil 71R Retarder slows the cure of PlatSil products. Adding 1% of 71R to the total mixed weight roughly doubles the pour time. Adding 2% of 71 R triples the pour time. Experiment to determine the amount that is best suited for your application. Do not exceed 4% as the system may not cure at all. NOTES: Add Part R to Part A prior to mixing with Part B.
