Title:
CYCLIC ORGANOPOLYSILOXANE, SILICONE COMPOSITION, ADHESIVE AUXILIARY AGENT, AND ADHESIVE
Document Type and Number:
WIPO Patent Application WO/2024/062973
Kind Code:
A1
Abstract:
The present invention is a cyclic organopolysiloxane characterized by being represented by general formula (1). Thus, provided are: a cyclic organopolysiloxane that has excellent adhesiveness to metal and resin and that provides an adhesive auxiliary agent capable of stably imparting adhesiveness even when exposed to a high-temperature, high-humidity environment for a long period of time; a silicone composition that contains the cyclic organopolysiloxane; an adhesive auxiliary agent; and an adhesive. (In the formula, each R1 is independently an alkylene group having 1-8 carbon atoms, m is an integer of 1-3, n is an integer of 1-3, and the sum of m and n is 4-6. The siloxane units may be arranged in any order.)
