A method of preparing a composition containing a fluorocarbon thermoplastic randomncopolymer comprising the steps of:n (A) providing a mixture having:n (i) a fluorocarbon thermoplastic random copolymer having subunits of:n ―(CH 2 CF 2 )x―, ―(CF 2 CF(CF 3 )y―, and ―(CF 2 CF 2 )z―, n whereinn x is from 1 to 50 or 60 to 80 mole percent, y is from 10 to 90 mole percent, z is from 10 to 90 mole percent, x + y + z equals 100 mole percent; (ii) a filler comprising zinc oxide; (iii) a curable amino functional polydimethyl siloxane copolymerncomprising aminofunctional units selected from the groupnconsisting of (aminoethylaminopropyl) methyl, (aminopropyl)nmethyl and (aminopropyl) dimethyl; and (iv) antimony-doped tin oxide particles; (v) a bisphenol residue curing agent; and (B) curing the mixture for 5 to 10 hours at a temperature in the range ofn25° C to 275° C. |
