PURPOSE:To provide an anti-icing material compsn. exhibiting an excellent effect, by mixing a specified silicone resin with an alkali metal compd. CONSTITUTION:70-99.8wt% organopolysiloxane resin having a number-average MW of 300-1,000,000 of formulaI(wherein R is H, a monovalent org. group attached to a silicon atom through a carbon-to-silicon bond; R' is H, a 1-20C alkyl, acyl, aryl, oxime residue; n, m are each less than 4 with the proviso that n+m<4) such as Z-6018 (a product of Dow Chemical) and 0.2-30wt% alkali metal compd. of formula II (wherein M is an alkali metal; X is an inorg. acid radical, hydroxyl group, an org. acid radical; a is 1-4), pref. a lithium compd. are mixed by using steel ball mill or pebble mill to disperse them in each other. |
