Grafted, thermoplastic, waterborne polymer and coating composition |
摘要 |
A water reducible resin for use in a coating composition is produced by grafting in organic solvent a thermoplastic polymer onto a thermosetting polymer that has been copolymerized with acid group-containing monomers to render the resultant polymer water soluble. Thermoplastic polymer is also grafted onto a phosphatized polyepoxide for the sake of adhesion of a coating to a substrate. A film formed from a waterborne coating composition containing the grafted polymers as a binder has both the toughness properties characteristic of a thermoplastic and the flexibility properties of a thermosetting resin.
