Applications
  • Cure is accomplished by simply mixing equal parts (1:1) by weight of part A and part B. Oven cure at 150 C-200°C (302 F- 392°F) for one to six minutes, depending on oven, coating thickness and type of fabric used.
  • Curing may be retarded and prevented by nitrogen compounds such as amines and amides, sulfur compounds, anti-aging additives and other additives in rubbers and plastics. Therefore, a materials compatibility test is always recommended.
  • Distinguishing Features ELASTOSIL® LR 6294 A/B when fully cured at recommended conditions is suitable for FDA requirements for 21 CFR 175.300.
