Part R Retarder slows the working time of the Poly Optic 14-serie products. The crystal clear cast resin Poly Optic 1411 has a processing time of 9 minutes but with 1% addition of the Part R it can be doubled by 18 minutes. Part R also ensures that less heat is released (exothermic heating) during the curing process.
