Abstract

A one-component composition comprising: 1) a ketimine which is the reaction product of: a) a dimer diamine; and b) a ketone; and 2) a blocked isocyanate.

Claims (24)

1 . A one-component composition comprising:

1) a ketimine which is the reaction product of:

a) a dimer diamine; and

b) a ketone; and

2) a blocked isocyanate.

2 . The one-component composition of claim 1 , wherein:

the ketimine comprises the reaction product of

a) (12E,15E)-N-[(21E,24E)-hexatriaconta-21,24-dienyl]hexatriaconta-12,15-dien-1-amine; and

b) a ketone selected from the group consisting of methyl isobutyl ketone, acetone, methyl ethyl ketone, diethyl ketone, diisobutyl ketone, cyclohexanones and acetophenones.

3 . The one-component composition of claim 2 , wherein the ketone comprises methyl isobutyl ketone.

4 . The one-component composition of claim 1 , wherein the blocked isocyanate comprises a phenolic blocking agent or an oxime.

5 . The one-component composition of claim 1 , wherein the blocked isocyanate comprises a urethane prepolymer based on toluene diisocyanate having blocked isocyanate functionality.

6 . The one component composition of claim 1 , wherein the composition is a sealant composition.

7 . The one component composition of claim 1 , further comprising plasticizers and fillers.

8 . The one component composition of claim 1 , wherein the blocked isocyanate has a functionality of greater than 1.5.

9 . A one-component composition comprising:

1) a ketimine which is the reaction product of:

a) 12E,15E)-N-[(21E,24E)-hexatriaconta-21,24-dienyl]hexatriaconta-12,15-dien-1-amine; and

b) a ketone selected from the group consisting of methyl isobutyl ketone, acetone, methyl ethyl ketone, diethyl ketone, diisobutyl ketone, cyclohexanones and acetophenones a dimer diamine; and

2) a blocked isocyanate comprising a phenolic blocking agent or an oxime

10 . The one-component composition of claim 9 , wherein the blocked isocyanate comprises a urethane prepolymer based on toluene diisocyanate having blocked isocyanate functionality.

11 . The one component composition of claim 9 , wherein the composition is a sealant composition.

12 . The one component composition of claim 9 , further comprising plasticizers and fillers.

13 . The one component composition of claim 9 , wherein the blocked isocyanate has a functionality of greater than 1.5.
