Technical Data Sheet

RTV88

RTV31, RTV60 and RTV88 silicone rubber compounds are high temperature 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.

RTV31, RTV60 and RTV88 silicone rubber compounds differ primarily in viscosity in the uncured state.
