Recyclable cold curing aqueous coating composition and method for recycling it |
摘要 |
<p>The present invention provides a recyclable cold curing aqueous coating composition, comprising (a) an oxidative-polymerizable, modified epoxy resin with an acid value of 25 to 60, comprising 20 to 70 percents by weight of an epoxy resin based on the total weight of said modified epoxy resin, of which a particle size is not more than 200 nm in an aqueous medium, (b) an anticorrosive pigment and/or an ampholytic metal oxide and (c) a drier. The recyclable cold curing aqueous coating composition of the present invention can provide a coating film having improved water resistance and corrosion resistance, and repeatedly reuse by recycling and readjusting. The present invention also provides a method for recycling the cold curing aqueous coating composition.</p> |
