<p><P>PROBLEM TO BE SOLVED: To provide a primer composition for a fluorinated elastomer or a fluorinated gel. <P>SOLUTION: The primer composition comprises 100 pts. mass of (a) a linear perfluoropolyether compound having at least two alkenyl groups per molecule and having a perfluoropolyether structure in the main chain, (b) a fluorine-containing organosiloxane compound having at least two SiH bonds per molecule, in such an amount that a ratio (SiH/alkenyl) of the SiH bond in the organosiloxane compound to the alkenyl group in the component (a) ranges from 0.8 to 5.0, (c) a hydrosilylation catalyst, (d) 5 to 100 pts. mass organosiloxane compound having, per molecule, at least one epoxy group and/or at least one trialkoxysilyl group bonded to a silicon atom of the organosiloxane via an organic group, and (e) an organic solvent containing a fluorine atom and having≤150°C boiling point at atmospheric pressure in an amount of 100 to 10,000 pts. mass, based on total 100 pts. mass total components (a), (b), (c) and (d). <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
