POLYSILOXANE HAVING PERFLUOROALKYL GROUP, ITS COMPOSITION AND MATERIAL FOR PREVENTING SNOW AND ICE ACCRETION

摘要

PROBLEM TO BE SOLVED: To provide a material having snow and ice accretion preventing effect in snowing weather or at a low temperature and snow-slipping performance at increased temperature. SOLUTION: The polysiloxane has at least one hydroxy group bonded or alkoxy group bonded to Si atom in one molecule, has a silicon atom number of 2-100 and contains at least one perfluoroalkyl group in one molecule.
