Patent ID: 8580073

Claim:
A process for preparing a laminate article comprises: (i) applying by spraying or fiberizing, onto a first substrate, a hot melt adhesive composition having a viscosity ranging from 5,000 to 30,000 mPa·s at 125° C., where the hot melt adhesive composition comprises: (1) 55 to 62 parts of a silicone resin having a silicon-bonded hydroxyl group content of less than 0.7 wt % based on the total weight of the silicone resin and comprising monofunctional units represented by R 1 3 SiO 1/2 and tetrafunctional units represented by SiO 4/2 where R 1 is a substituted or unsubstituted monovalent hydrocarbon radical, (2) 38 to 45 parts of an organopolysiloxane comprised of difunctional units of the formula R 2 R 3 SiO and terminal units of the formula R 4 a X′ 3-a SiG— wherein R 2 is an alkoxy group or a monovalent unsubstituted or substituted hydrocarbon radical; R 3 is a monovalent unsubstituted or substituted hydrocarbon radical; R 4 is aminoalkyl or R 1 group, X′ is a hydrolyzable group; G is an oxygen atom or a divalent group linking the silicon atom of the terminal unit with another silicon atom and a is 0 or 1, (3) 0.1 to 5 parts of a silane crosslinker per hundred per part of silicone resin and organopolysiloxane, and (4) 0.02 to 2 parts of a titanate catalyst per hundred per part of silicone resin and organopolysiloxane; with the provisos that the hot melt adhesive composition is free of filler and the hot melt adhesive composition has a nonvolatile content of 97.5% to 100%, thereby forming a film; (ii) contacting a second substrate with the film; and (iii) curing the hot melt adhesive composition.
