Momentive DBT (dibutyl tin) Catalyst 28g

Momentive DBT(dibutyl tin dilaurate) is the liquid curing agent generally preferred for most applications. Used in concentrations from 0.1 to 0.5% by weight, DBT provides adequate work time and moderate cure speed. The effects of varying DBT concentration are shown in the table of typical cure rates. Varying the concentration within the limits shown has little or no effect upon the final cured properties of the RTV silicone rubber compound. 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. Momentive DBT boasts simple handling procedures and equipment for easy use and low processing cost. Momentive DBT allows adjustable work time and cure rate obtainable through choice of concentration by weight used. DBT can be used from 0.1% to 0.5% by weight.
