ORGANOPOLYSILOXANE COMPOSITION FOR FORMING EXFOLIATIVE HARDENED FILM, AND EXFOLIATIVE SHEET-LIKE BASE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an organopolysiloxane composition which is for forming an exfoliative hardened film and can form a homogeneous hardened film in the high-speed coating, the hardened film having a high residual adhesion ratio and good exfoliation characteristics; and to provide an exfoliative sheet-like base material having the hardened film consisting of the composition. SOLUTION: The organopolysiloxane composition for forming an exfoliative hardened film contains an organopolysiloxane which has at least one fluorine-atom-containing organic group selected from the groups represented by the following general formulas and at least two alkenyl groups or at least two hydrogen atoms bonded to silicon atoms. The organopolysiloxane composition is applied onto a sheet-like base material and hardened to give the exfoliative sheet-like base material. The general formulas are -R2-CnF2n+1, -R2-O-R2-CnF2n+1, and -R2-O-R2-CF(CF3)(OCF2CF(CF3))nF (wherein R2is a divalent hydrocarbon group; and n is an integer of 1-20). COPYRIGHT: (C)2007,JPO&INPIT
