ELASTOSIL® LR 6289 A/B

ELASTOSIL® LR 6289 A/B is a commercial grade two-component system that cures rapidly upon heating to a silicone rubber. It has been formulated as a moderate viscosity, high performance liquid rubber with good heat resistance.



Cure is accomplished by simply mixing equal parts (1:1) by weight of part A and part B. ELASTOSIL® LR 6289 A/B is not easily deaired and should be mixed in an airless system.
Vulcanization ELASTOSIL® LR 6289 A/B is vulcanized by mixing part A with part B in a ratio of 1:1 with the application of heat. Cure initiation is exhibited at 325F / 150°C recommended for 3 minutes depending on application and thickness. Distinguishing Features ELASTOSIL® LR 6289 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.

Storage

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.
