Polyteks’ Poly-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. Exothermic heating causes distortion, waviness and shrinkage especially in castings > 0.5″ thick. For additional information, read the Poly-Optic 14-Series Technical Bulletin.
