摘要:
The invention relates to a low-monomer NCO prepolymer composition of the type A-B-A, which is obtained by reacting CH-acidic compounds with diisocyanates, and methods for the production and use thereof.
摘要:
The present invention relates to polyurethane compositions containing uretdione groups that can be cured at a low temperature and are intended more particularly for polyurethane powder coating compositions and adhesive compositions, to a process for preparing them and to their use.
摘要:
The invention relates to prepregs and composite components (molding) produced therefrom at a low temperature, obtainable by using powdery highly reactive polyurethane compositions containing uretdione groups, with specific catalysts.
摘要:
The invention relates to reactive compounds on the basis of transesterification, comprising A1) at least one dicarboxylic or polycarboxylic acid ester component comprising at least two or more ester groups, comprising at least one monofunctional alcohol having a mean molar mass Mn of less than or equal to 200 g/mol as the esterification component and A2) at least one diol or polyol component having at least two or more OH groups and/or B) at least one component carrying carboxylic acid ester groups, comprising at least one monofunctional alcohol having a mean molar mass Mn of less than or equal to 200 g/mol as the esterification component, and alcohol groups; and C) bismuth triflate as the catalyst; D) optionally further auxiliary agents.
摘要:
The invention relates to radiation-curable formulations which contain adhesion promoters containing phosphoric acid and which in the cured state afford a particular degree of corrosion control for metallic substrates, and to a process for preparing them.
摘要:
The present invention relates to the use of oligomeric siloxane components in radiation-curable formulations which in the cured state offer a particular degree of corrosion control for metallic substrates.
摘要:
The invention relates to high-reactivity polyurethane compositions which contain uretdione groups and cure at low baking temperatures, to a process for the preparation and to their use for producing coating materials, especially surface coatings and adhesives, and also plastics.
