## Abstract

Provided is a two-part composition comprising A) An epoxy terminated polyester having the structure wherein R1— is G- is j is 0 to 5, —R2— is a divalent organic group, —R22— is a divalent alkyl group, and —R22— is a divalent alkyl group, and B) one or more epoxy curing agent, each molecule of which comprises two or more active hydrogen atoms that are each capable of reacting with an epoxy group.

## Claims

### Claim 1

A two-part composition comprising
A) an epoxy terminated polyester having the structure
wherein R1— is
G- is
j is 0 to 5, —R2— is
wherein said —R3— and —R4— and —R5— is each independently a divalent organic group, and wherein said p is 0 to 20,
wherein said —R3— is either —(CH2)q— or
wherein q is 1 to 8,
and wherein —R21— is a divalent alkyl group, and —R22— is a divalent alkyl group, and
B) one or more epoxy curing agent, each molecule of which comprises two or more active hydrogen atoms that are each capable of reacting with an epoxy group.

### Claim 2 (depends on 1)

The composition of claim 1, wherein each of said active hydrogen atoms is part of a primary or secondary amine group.

### Claim 3 (depends on 1)

The composition of claim 1, wherein said curing agent is selected from the group consisting of phenalkamines, Mannich bases, phenalkamides, amine terminated amide resins, aminoimidazolines, and mixtures thereof.

### Claim 4 (depends on 1)

The composition of claim 1, wherein said curing agent has number-average molecular weight of 750 or greater, and wherein the amount of said curing agent having molecular weight of less than 500 is 25% or less by weight based on the weight of said curing agent.

### Claim 5 (depends on 1)

The composition of claim 1, wherein said —R21— has 3 carbon atoms and every —R22— has 3 carbon atoms.

### Claim 6 (depends on 5)

The composition of claim 5, wherein at least one —R22— has the structure selected from

### Claim 7 (depends on 1)

The composition of claim 1, wherein said —R4— is either —CH2—CH2— or —CH2—CH2—O—CH2—CH2—.

### Claim 8 (depends on 1)

The composition of claim 1, wherein said —R21— has 5 or fewer carbon atoms, and every said —R22— has 5 or fewer carbon atoms.
