Dispersed particulate composition

摘要

A sealant or mastic composition comprises a dispersion of a finely divided particulate solid in a silicone resin formulation which contains a dispersant containing at least one group of the formula -(O-A-CO)n-. The dispersant may be derived from a hydroxycarboxylic acid and preferably has a -COOH end group. The dispersant modifies the shear properties of the sealant.
