Title:
アロファネート基及びシラン基を含む高官能性ポリイソシアネート
Document Type and Number:
Japanese Patent JP5751789
Kind Code:
B2
Abstract:
Producing allophanate group containing polyisocyanate, comprises: reacting (a) at least one silane groups exhibiting hydroxyurethane and/or hydroxyamide obtainable by reacting aminosilanes with cyclic carbonates or lactones, and (b) at least one further polyhydric hydroxy functional component, with (c) at least one diisocyanate with aliphatically, cycloaliphatically, araliphatically and/or aromatically bound isocyanate groups in molar excess amount, based on the isocyanate reactive groups of the components (a) and (b); and optionally subsequently removing the unreacted diisocyanate excess. Producing allophanate group containing polyisocyanate, comprises: reacting (a) at least one silane groups exhibiting hydroxyurethane and/or hydroxyamide obtainable by reacting aminosilanes with cyclic carbonates or lactones, and (b) at least one further polyhydric hydroxy functional component having a molecular weight of 62-2000 g/mol, with (c) at least one diisocyanate with aliphatically, cycloaliphatically, araliphatically and/or aromatically bound isocyanate groups in molar excess amount, based on the isocyanate reactive groups of the components (a) and (b); and optionally subsequently removing the unreacted diisocyanate excess. Independent claims are also included for: (1) an allophanate group containing polyisocyanate, obtainable by the above method; and (2) a coating agent comprising allophanate groups bearing polyisocyanate and a substrate coated with this coating agent.
