ELASTOSIL® LR 6294 A/B Liquid Silicone Rubber is a two-component, solventless liquid silicone rubber system that cures rapidly upon heating to a tough silicone rubber. It has been formulated primarily as a high strength, moderate viscosity liquid rubber for fabric coating.


  • 100% solids
  • Good adhesion 
  • High tensile strength and elongation

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 Resinous and Polymeric Coatings and 21 CFR 177.2600 Rubber Articles for Repeated Use subject to the total extractive limits as specified and published in the CODE OF FEDERAL REGULATIONS*. * Because this regulation contains limitations, compliance to the regulation is the responsibility of the user.


The "Best use before end date" of each batch is shown on the Certificate of Analysis. Storage beyond the date specified on the Certificate of Analysis does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
