| 摘要 |
This invention provides a coating composition comprising a binder and an aqueous carrier, the binder comprising from 70-90% by weight of a sterically stabilised dispersion of a thermosetting acrylic polymer, an amount being in the range 2-30% by weight of a bisphenol-A epichlorhydrin condensate or novolac epoxy resin provided that the amount is below that which causes instability of the dispersion, and from 0.1 to 10% by weight of an acid catalyst based on the total binder, where the steric stabilising agent is polyvinyl pyrrolidone having a molecular weight of 2,000 - 500,000. |
