Document Type and Number:
WIPO Patent Application WO/2023/004743
Kind Code:
A1
Abstract:
Disclosed is a solventless adhesive composition comprising (A) an isocyanate component obtained by the reaction of reactants comprising at least one monomeric C2-C16 isocyanate compound and at least one first polyol; and (B) a polyol component comprising a silane coupling agent and particularly selected polyol(s). The solventless adhesive composition can be used for the production of laminate materials, e.g. exterior roofing laminate material, which well meets the requirements of various compliance regulations and has superior performance properties such as bond strength, weathering resistance, yellowing resistance, cracking resistance, delamination resistance, and the like. A method for producing said laminate material and the resultant laminate material are also disclosed.
