Abstract

The invention relates to a primary amine component corresponding to formula I being (R 1 R 2 NR 3 ) 2 NR 4 wherein
each of R 1 and R 2 are chosen from the group consisting of a methyl group, an ethyl group, an iso-propyl group and an n-propyl group; R 3 being an alkoxyalkyl group chosen from the group consisting of —CH 2 CH 2 OCH 2 CH 2 —, —CH 2 CH 2 OCH 2 CH 2 CH 2 — and —CH 2 CH 2 CH 2 OCH 2 CH 2 CH 2 —; R 4 is chosen from the group consisting of a hydrogen and —CH 2 CH 2 CH 2 NH 2 ,

and the use of said primary amine component corresponding to Formula I as a blowing catalyst of a catalyst system in a reaction of at least one polyisocyanate component and at least one isocyanate-reactive component, the catalyst system further comprising at least one gelling catalyst different from said component of formula I.

First claim

The invention claimed is:

1. A catalyst system suitable for catalyzing the reaction of a polyisocyanate component, water and an isocyanate-reactive component to provide a foamed polyurethane or polyurea material, said catalyst system comprising at least a first catalyst suitable as a gelling catalyst in a reaction of a polyisocyanate component and an isocyanate-reactive component and a second catalyst, different from said first catalyst and suitable as a blowing catalyst in a reaction of a polyisocyanate component and an isocyanate-reactive component, said second catalyst being a component according to formula I, formula I being (R 1 R 2 NR 3 ) 2 NR 4 , wherein
each of R 1 and R 2 are chosen from the group consisting of a methyl group, an ethyl group, an iso-propyl group and an n-propyl group;
R 3 is an alkoxyalkyl group chosen from the group consisting of —CH 2 CH 2 OCH 2 CH 2 —, —CH 2 CH 2 OCH 2 CH 2 CH 2 —, and —CH 2 CH 2 CH 2 OCH 2 CH 2 CH 2 —; and
R 4 is chosen from the group consisting of hydrogen and —CH 2 CH 2 CH 2 NH 2 .

2. A primary amine corresponding to formula I, formula I being (R 1 R 2 NR 3 ) 2 NR 4 wherein
each of R 1 and R 2 are chosen from the group consisting of a methyl group, an ethyl group, an iso-propyl group and an n-propyl group;
R 3 is an alkoxyalkyl group chosen from the group consisting of —CH 2 CH 2 OCH 2 CH 2 —, —CH 2 CH 2 OCH 2 CH 2 CH 2 —, and —CH 2 CH 2 CH 2 OCH 2 CH 2 CH 2 —; and
R 4 is —CH 2 CH 2 CH 2 NH 2 .

3. The system according to claim 1 , wherein R 4 is hydrogen.

4. The system according to claim 3 , wherein R 1 and R 2 are methyl groups.

5. The system according to claim 1 , wherein R 4 is —CH 2 CH 2 CH 2 NH 2 .

6. The system according to claim 1 , wherein
each of R 1 and R 2 are a methyl group;
R 3 is —CH 2 CH 2 OCH 2 CH 2 —; and
R 4 is hydrogen.
