Retarder for RU-500 Series (500R)
Extended Work Times (Gel Time) may be required when casting large or intricate parts with RU-500 Series Clear Systems. 500R is an additive used to retard and prolong the gel times of these systems. Add and blend 500R to Part B prior to the addition of Part A. Increase the amount of Part A by an equal amount of 500R used. Since cure time of material will be extended, prematurely de-molding parts before a full cure will result in sagging or distorted parts. Complete Cure by Post Curing parts for 12-14 hours@ 130-140F or leave parts at room temperature for 7days @70F.
