Momentive RTV11-1P

General Purpose Dual-Component Liquid Silicone Rubber Potting Encapsulant, White, 1 Pint Kits

(Case of 12)

RTV11 silicone rubber compound is a general-purpose two-part silicone elastomer. It is supplied ready-to-use with a base compound and DBT (dibutyl tin dilaurate) as the standard curing agent. DBT is suitable for most applications, however, other catalysts are available to facilitate deep section cure, faster cure, and automated mixing.

Work time and cure rates can be varied
Room temperature cure
Composition free of solvents and solvent odor
FDA compliance - RTV11 and RTV41 silicone rubber compounds can be used in food contact applications other than contact with acidic foods where FDA regulations apply.
Excellent adhesion capabilities with primer
Excellent release properties
Retention of elastomeric properties at temperatures from -54°C (-65°F) up to 204°C (400°F) continuously, and up to 260°C (500°F) for short periods of time.
