Smooth-Sil™ 933 Flame Out is designed specifically for flame rated gasket and potting applications.

Smooth-Sil™ 933 Flame Out is a Shore 33A platinum silicone that is mixed 1A:1B by volume or weight. Rubber cures at room temperature (73°F/23°C) with negligible shrinkage. Vacuum degassing is recommended to minimize air bubbles in cured rubber. Cured material is rated to UL 94 V-0

Smooth-Sil™ 933 cures in 6 hours to a soft, strong rubber that is tear resistant and exhibits very low long term shrinkage. An infinite number of color effects can be achieved by adding Silc Pig™ silicone pigments. Applications include electrical potting for flame resistant enclosures, creating gaskets for medical devices and electrical appliances and other applications where a flame resistant, flexible silicone seal is required.
