Abstract
Official abstract text for this publication.
This invention relates to an epoxy resin composition and its application in marine maintenance and repair coating with improved overcoatability.
First claim
Opening claim text (preview).
The invention claimed is: 1. A curable composition comprising, based on the total weight of the curable composition: a) from 1 wt. % to 20 wt. % of an epoxy compound I selecting from aromatic epoxy compounds, alicyclic epoxy compounds, or a mixture thereof; b) from 1 wt. % to 20 wt. % of a chlorinated polyolefin based terpolymer of vinyl chloride, vinyl acetate, and vinyl alcohol; and c) from 20 wt. % to 40 wt. % of a curing agent. 2. The curable composition according to claim 1 which further comprises from 0.4 wt. % to 10 wt. % of an epoxy compound II selecting from acyclic aliphatic epoxy compounds. 3. The curable composition according to claim 1 wherein the epoxy compound I is bisphenol A diglycidyl ether, bisphenol F diglycidyl ether, or a mixture thereof. 4. The curable composition according to claim 2 wherein the epoxy compound II is glycerol diglycidyl ether, poly(propylene glycol) diglycidyl ether with an average molecular weight (Mw) from 300 to 1000, or the mixture thereof. 5. A coating composition comprising, based on the total weight of the coating composition: a) from 25 wt. % to 45 wt. % of a cured epoxy compound I selecting from aromatic epoxy compounds, alicyclic epoxy compounds, or a mixture thereof; b) from 1 wt. % to 20 wt. % of a chlorinated polyolefin based terpolymer of vinyl chloride, vinyl acetate, and vinyl alcohol; and c) from 35 wt. % to 65 wt. % of a filler. 6. The coating composition according to claim 5 which further comprises from 0.4 wt. % to 25 wt. % based on the total weight of the coating composition, of a cured epoxy compound II selecting from acyclic aliphatic epoxy compounds. 7. The curable composition according to claim 1 , wherein the curing agent comprises a phenalkamine. 8. The coating composition according to claim 5 , wherein cured epoxy compound I is cured with a curing agent comprising a phenalkamine.
