Abstract

The present invention provides a tris (alkoxycarbonylamino) triazine (TACT) composition, coating composition comprising the same, and manufacturing method thereof. The tris (alkoxycarbonylamino) triazine composition comprises TACT and dibutyl carbonate (DBC); wherein the DBC ranges from 2 to 11 wt % of total weight of the composition. Through the usage of the coating composition comprising the composition of the present invention, the coating film surface of the coated object can have excellent film surface appearance.

First claim

What is claimed is:

1. A tris (alkoxycarbonylamino) triazine (TACT) composition, comprising TACT and dibutyl carbonate (DBC), wherein a weight percentage of the DBC ranges from 3.66 to 11 wt % of a total weight of the composition, wherein a solid content of the composition is 48 to 52 wt %.

2. The composition according to claim 1 , wherein the weight percentage of the DBC ranges from 3 to 8 wt % of total weight of the composition.

3. The composition according to claim 1 , wherein the TACT has a structure as formula (I) below:

wherein each of R 2 , R 3 and R 5 is independently H, NR 7 R 8 or an aliphatic group; R 1 , R 4 and R 6 are C1-C6 alkyl; each of R 7 and R 8 is independently H, an aliphatic group, an alkoxy group or a carbamate group.

4. The composition according to claim 3 , wherein R 2 , R 3 and R 5 are H.

5. The composition according to claim 1 , wherein the composition has a pH value of 4.5 to 7.0 at 25° C.

6. The composition according to claim 1 , wherein a viscosity of the composition at 25° C. is 10 to 30 cps.

7. A process of preparing the composition according to claim 1 , comprising reacting a compound of formula (II) below

with carbonate in the presence of an alcohol and a base,
wherein in formula (II), each of R 1 -R 6 is independently H, NR 7 R 8 or an aliphatic group, and each of R 7 and R 8 is independently H, an aliphatic group, an alkoxy group or a carbamate group.

8. The process according to claim 7 , after completion of the reaction of the compound of formula (II) with carbonate in the presence of the alcohol and the base, further comprising additionally adding DBC.

9. The process according to claim 7 , wherein the carbonate is dimethyl carbonate.

10. The process according to claim 7 , wherein the base is alkali metal alkoxide or alkaline earth metal alkoxide.

11. The process according to claim 10 , wherein the alkali metal alkoxide is sodium tert-butoxide or sodium methoxide.

12. A coating composition, comprising the composition according to claim 1 , wherein the composition is for use as a crosslinking agent.
