Document Type and Number:
Japanese Patent JP6297558
Kind Code:
B2
Abstract:
An aqueous dispersion comprises a silicone composition dispersed in an aqueous phase. The silicone composition comprises a product of a reaction of (a) an alkenyl-containing organopolysiloxane having an average per molecule of at least 2 alkenyl groups and (b) an Si H containing siloxane having an average per molecule of at least 2 Si H moieties. The dispersion also comprises a hydrosilylation catalyst, a polymeric film former and a surfactant of molecular weight below 1600. The composition is stabilised in dispersion form by the surfactant dissolved in the aqueous phase and the polymeric film former, and is capable of forming a tacky layer on drying.
