Title:

POLYSILOXANE AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2019/098163

Kind Code:

A1

Abstract:

This polysiloxane: comprises a hydrolytic condensation product of a silicon compound that contains a cyclic alkoxysiloxane represented by formula (1) (in the formula, R1 groups each independently denote a substituted or unsubstituted alkyl group having 1-3 carbon atoms, R2 groups each independently denote a substituted or unsubstituted alkyl group having 1-6 carbon atoms, and n denotes an integer between 3 and 8); has at least two hydrosilylable carbon-carbon unsaturated groups per molecule; has at least two hydrosilyl groups per molecule; and in which the inequality 0.25 ≤ t1 < 1 is satisfied, where t1 denotes the molar ratio of T units having a group represented by R1 relative to all siloxane units in the hydrolytic condensation product. The polysiloxane is addition crosslinkable, and is therefore suitable as a binder component of a heat-resistant paint or the like or as a coating material.
