積層接着剤組成物及びその使用
Document Type and Number:
Japanese Patent JP7254030
Kind Code:
B2
Abstract:
Two part silicone lamination adhesive compositions which cure via a condensation cure chemistry using titanium and/or zirconium based catalysts at room temperature are disclosed. The compositions comprise: (i) at least one condensation curable silyl terminated polymer having at least one hydrolysable and/or hydroxyl functional group(s) per molecule; (ii) a cross-linker; and (iii) a condensation catalyst selected from the group of titanates and zirconates. Polymer (i) is not stored in the same part as cross-linker (ii) and catalyst (iii). Catalyst (iii) is present in a molar amount which is at least 50% of the moisture present cumulatively in the parts of the composition. The molar ratio of silicon bonded hydroxyl groups in polymer (i) to hydrolysable groups in cross-linker (ii) is above 0.15. The molar ratio of the silicon bonded hydroxyl groups in polymer (i) to M-OR functions is greater than 10, where M is titanium or zirconium.
