Patent ID: 8088869

Claim:
A hot melt sealant/adhesive composition containing: A. component A: a siloxane polymer composition comprising a) an organopolysiloxane which comprises not less than two groups selected from i) silicon-bonded alkenyl groups or ii) silicon-bonded hydroxyl groups and/or silicon-bonded hydrolysable groups b) one or more fillers; and a cure system comprising c) a suitable catalyst and where required d) a suitable cross-linker adapted to react with component (a), catalysed with component (c); and both of components B and C wherein: B. is one or more hot melt resins having a T g of less than 25° C.; and C. is one or more waxes having a melt temperature of between 40 and 200° C.; and an organic resin different from component B and having a viscosity average molecular weight of from 200 to 6000 and a softening point of from 0° C. and 150° C.; wherein the total amount of components B and C in the composition is from 2 to 60% by weight of the whole composition.
