HIGH-REACTIVITY POLYURETHANE COMPOSITIONS CONTAINING URETDIONE GROUPS AND COMPRISING CARBONATE SALTS |
摘要 |
A high-reactivity polyurethane composition useful in coatings and adhesives, contains the following components A)-D): A) 5 to 98.7 wt %, based on the total mass of the components, of at least one compound containing an uretdione group, and a free NCO content of less than 5 wt %, and an uretdione content of 2 to 25 wt %, based on i) aliphatic and/or (cyclo)aliphatic and/or cycloaliphatic polyisocyanates and ii) compounds containing hydroxyl groups; B) 0.2 to 5 wt %, based on the total mass of the components, of at least one catalyst selected from the group consisting of a substituted carbonate salt having a quaternary ammonium counterion, a substituted carbonate salt having a quaternary phosphonium counterion and mixtures thereof; C) 0.1 to 10 wt %, based on the total mass of the components, of at least one cocatalyst having at least one epoxide group; D) 1 to 90 wt %, based on the total mass of the components, of at least one polymer containing a hydroxyl group and having an OH number of between 20 and 1000 mg KOH/gram; wherein a sum of all components A)-D) is 100 wt %. |

1. A high-reactivity polyurethane composition comprising an uretdione group, said composition comprising the following components A)-D):
A) 5 to 98.7 wt %, based on the total mass of the components, of at least one compound containing
an uretdione group, anda free NCO content of less than 5 wt %, andan uretdione content of 2 to 25 wt %, based on i) aliphatic and/or (cyclo)aliphatic and/or cycloaliphatic polyisocyanates and ii) compounds containing hydroxyl groups; B) 0.2 to 5 wt %, based on the total mass of the components, of at least one catalyst selected from the group consisting of a substituted carbonate salt having a quaternary ammonium counterion, a substituted carbonate salt having a quaternary phosphonium counterion and mixtures thereof; C) 0.1 to 10 wt %, based on the total mass of the components, of at least one cocatalyst having at least one epoxide group; D) 1 to 90 wt %, based on the total mass of the components, of at least one polymer containing a hydroxyl group and having an OH number of between 20 and 1000 mg KOH/gram; wherein a sum of all components A)-D) is 100 wt %. |
