Abstract

Curable compositions are made from a blend of an epoxide resin and a polyacrylate or polymethacrylate ester. Such compositions cure rapidly even at low temperatures when mixed with aliphatic polyamines and are useful in coating and adhesive applications.

Claims

1. A curable composition which comprises:

(1) a blend of an epoxide resin containing more than one 1,2-epoxy group per molecule and a polyacrylate or polymethacrylate ester of a polyol wherein said ester contains more than one terminal acrylate or methacrylate group, the epoxide resin and the ester being present in the weight ratio of about 100 parts of epoxide resin to about 5 to about 100 parts of ester; and

(2) an aliphatic polyamine curing agent containing at least 3 amine hydrogen atoms per molecule in the amount of about 0.75 to about 1.25 amine hydrogen atoms for each epoxy group of the epoxide resin and for each acrylic unsaturated group of the polyacrylate or polymethacrylate ester said amine atoms reacting with the epoxide ring and adding across the double bond of the acrylate group of the composition.

2. The composition of claim 1 wherein the epoxide resin is a glycidyl polyether or polyester having an epoxide equivalent weight of about 100 to about 2000.

3. The composition of claim 1 wherein the epoxide resin is a glycidyl polyether of a polhydric phenol having an epoxide equivalent weight of about 110 to about 500.

4. The composition of claim 3 wherein the expoxide resin is a glycidyl polyether of bis(4-hydroxyphenyl)-2,2-propane having an epoxide equivalent weight of about 175 to about 250.

5. The composition of claim 1 wherein the polyacrylate ester is 1,6-hexanediol diacrylate.

6. The composition of claim 1 wherein the polyacrylate ester is trimethylolpropane triacrylate.

7. The composition of claim 1 wherein the aliphatic polyamine is a polyalkylene polyamine.

8. The composition of claim 7 wherein the polyalkylene polyamine is triethylene tetraamine.

9. The cured composition obtained from the composition of claim 1.
