Momentive RTV11 & DBT Catalyst White Silicone Rubber Compound

RTV11, RTV21 and RTV41 silicone rubber compounds are general purpose two-part silicone elastomers. They are 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.

Features:

• Work time and cure rates can be varied
• Room temperature cure
• Flowable
• 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.

DBT:

Several different curing agents are available for two-component RTV silicone rubber compounds to provide a choice of cure speed, mixing ratio, or deep section cure. DBT (dibutyl tin dilaurate) and STO (stannous tin octoate) are clear, easily pourable liquids. RTV9950 is a white paste, RTV9910 is a beige paste, and RTV9811 is a beige pourable paste. All are based on metal soaps. These curing agents are appropriate to use with the following Momentive Performance Materials products: RTV11, RTV21, RTV31, RTV41, RTV60, RTV88, RTV511, RTV560, and RTV577.

Features:

• Simple handling procedures and equipment for easy use and low processing cost.
• Adjustable work time and cure rate obtainable through choice of curing agent and level used.
