PlatSil 71 & 73 R Retarder
PlatSil 71 & 73 R can be used with all PlatSil silicone liquid rubbers to slow the cure and yield a longer working time. Adding ~1% (to the Part A first) of part R to the total A+B mixed weight roughly doubles the working time. Adding ~2% roughly triples the working time. Do not exceed 4%.
