Poly-Optic® 14 Part R Retarder - 8-lb unit Less than 10" Running Bond BlockPoly Optic 14 Series Part R Retarder slows the cure of Poly Optic products. For every part of Part R added, an equal part of Part A must be added to the mix. Experiment to determine how much is needed for your application. Do not exceed 4% of the total mixed weight as the product may not cure properly. Example: Add 1% Part R to Poly Optic 1411 to double the working time from 9 to 18 minutes. NOTES: Slowing the cure also reduces exothermic heating.
