  • Moisture curable organopolysiloxane composition and electric/electronic apparatus
    Patent number: 11702567
    Abstract: A moisture curable polyorganosiloxane composition is disclosed. The composition comprises: (A) a polyorganosiloxane endblocked with alkoxysilyl-containing groups at both molecular terminals; (B) a polyorganosiloxane resin having a content of OZ in a range of from about 50 mol % to about 150 mol %, wherein each Z is H or an alkyl group such that OZ represents a silanol group and/or a silicon atom-bonded alkoxy group; and (C) a polyorganosiloxane resin having an alkoxysilyl-containing group. The composition exhibits good to excellent coating performance without using a solvent. In addition, the composition can cure by contacting moisture in air to form a cured product exhibiting good to excellent mechanical properties.
