Abstract
An isocyanate reactive composition comprising At least one component selected from the group consisting of a polyether polyol, a polyester polyol, a polyether polyamide and a polyester polyamide; one or more amine components, each of said amine components having a given structure. In some embodiments, the average number of nitrogen atoms of said amine components is in the range of 5 to 10.
Claims12
A composition, comprising:
- at least one component selected from the group consisting of a polyether polyol, a polyester polyol, a polyether polyamide and a polyester polyamide;
- N-(3-dimethylaminopropyl)-N,N-diisopropanolamine;
- and
- one or more amine components having a structure according to one of the formulae:
- wherein Ra comprises 3 to 17 nitrogen atoms, Rb comprises 2 to 16 nitrogen atoms and each of Ra and Rb independently comprises a plurality of units selected from at least one of R1, R2, and R3, combined in a random sequence, wherein:
- R1 is
- R2 is
- and R3 is
- wherein each of R4, R5, R6 and R7 individually are —H or —CH3;
- and wherein the amount of the one or more amine components in the composition is between 0.05% wt and 1% wt calculated on the total weight of the composition.
A method for reducing the emission of at least one of formaldehyde and acetaldehyde from a polyurethane or polyurea foam, by using a composition comprising (i) N-(3-dimethylaminopropyl)-N,N-diisopropanolamine, and (ii) one or more amine components as an additive in a reaction mixture to produce said polyurethane or polyurea foam, each of said one or more amine components having a structure according to one of the formulae
- wherein Ra, comprises 3 to 17 nitrogen atoms, Rb comprises 2 to 16 nitrogen atoms and each of Ra and Rb independently comprises a plurality of units selected from at least one of R1, R2, and R3, combined in a random sequence, wherein:
- R1 is
- R2 is
- and R3 is
- wherein each of R4, R5, R6 and R7 individually are —H or —CH3;
- and
- wherein the amount of the one or more amine components in the composition is between 0.05% wt and 1% wt calculated on the total weight of the composition.
A composition, comprising:
- at least one component selected from the group consisting of a polyether polyol, a polyester polyol, a polyether polyamide and a polyester polyamide;
- N-(3-dimethylaminopropyl)-N,N-diisopropanolamine;
- and
- an amine selected from triethyltetramine (TETA), tetraethylpentamine (TEPA), pentaethylhexamine (PEHA), hexaethylheptamine (HEHA), heptaethyloctamine (HEOA), and octaethylenenonamine (OENO),
- wherein the amine is present in the composition in an amount between 0.05% wt. and 1% wt. calculated on the total weight of the composition.
