Abstract

The invention provides a composition capable of forming a coating film that is excellent in salt water resistance and weather resistance and is less likely to deteriorate for a long time. The composition contains a polyaspartic acid ester and a fluoropolymer.

First claim

1 . A composition comprising:
a polyaspartic acid ester; and a fluoropolymer.

2 . The composition according to claim 1 ,
wherein the polyaspartic acid ester is represented by the following formula (1):

wherein X is a n-valent group obtainable from an organic polyamine that contains n primary amino groups bonding to an acyclic or cyclic aliphatic structure and that has a number average molecular weight of 88 to 400 by removing the primary amino groups therefrom; R 1 and R 2 are the same as or different from each other, and are each a C1-C18 organic group; and n is an integer of 2 or greater.

3 . The composition according to claim 1 ,
wherein the fluoropolymer is a curable functional group-containing fluoropolymer.

4 . The composition according to claim 1 ,
wherein the fluoropolymer is a hydroxy-containing fluoropolymer.

5 . The composition according to claim 1 ,
wherein the polyaspartic acid ester and the fluoropolymer have a mass ratio of 5/95 to 95/5.

6 . The composition according to claim 1 , further comprising a curing agent.

7 . The composition according to claim 6 ,
wherein the curing agent is a polyisocyanate compound.

8 . The composition according to claim 1 , further comprising a solvent.

9 . The composition according to claim 1 , which serves as a coating.

10 . The composition according to claim 1 , which serves as a coating to be applied to an offshore structure or a port facility.

11 . A coating film obtainable from the composition according to claim 1 .

12 . The coating film according to claim 11 , which has a thickness of 100 to 1000 μm.

13 . A fluorine-containing coating film comprising:
a urethane bond; and a urea bond, and
exhibiting a corrosion from scribe of 1 mm or shorter.

14 . The fluorine-containing coating film according to claim 13 , which has a thickness of 100 to 1000 μm.

15 . A laminate comprising:
a base; and the coating film according to claim 11 .

16 . The laminate according to claim 15 , further comprising a layer formed of epoxy resin.

17 . The laminate according to claim 15 ,
wherein the base is formed of iron.

18 . A laminate comprising:
a base; and the fluorine-containing coating film according to claim 13 .
