PlatSil® 71/73 Part R Retarder slows the cure of PlatSil® products. Adding ~1% of Part R to the total mixed weight roughly doubles the pour time. Adding ~2% of Part 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. For additional information, read the Technical Bulletin associated with your product.
