ELASTOSIL® FLR 3905/40 A/B
Fluorinated liquid silicone rubber of the ELASTOSIL® FLR 3905 series are paste-like, easily-pigmentable two-component compounds. Its vulcanizates are noted for their improved resistance against fuel and oil. ELASTOSIL® FLR 3905 grades show low compression set without post-cure. A thin oil film with lubricating properties forms on the surface of the vulcanizates.
ELASTOSIL® FLR 3905/40 is a fast curing and oil bleeding fluorinated liquid silicone rubber with enhanced fuel and oil resistance.
The addition of heat stabilizers at service temperatures of more than 180 °C is recommended.
Further information to improve the heat stability by use of specific ELASTOSIL® Color Pastes FL can be obtained from the Technical Information Sheet "ELASTOSIL® Color Pastes FL".

Fluorosilicone of the ELASTOSIL® FLR 3905 series can form toxic gases at temperatures above 150 °C. A proper
ventilation has to be installed.
This product is available in 20 kg pail and 200 kg drum kits.
Once opened, containers should always be resealed after use to prevent the platinum catalyst from being poisoned by amines, sulphur or phosphorus compounds. The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label 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.
