Development of Ultralow Temperature Curing Epoxy Coating and Study of the Property
Low temperature curable epoxy anticorrosive coatings were prepared by special epoxy autocatalytic reaction and Michael addition exothermic reaction.The Tg of low temperature curing epoxy and ordinary epoxy curing coatings at different temperatures were contrast tested.,through the comparative calculations,The curing degree of low temperature curing epoxy at different temperatures is higher than that of ordinary room temperature curing epoxy.After testing the dry speed and anti-corrosive property of low temperature curing epoxy coating,get the result that this products not only has property of fast dry speed in low temperature but also has good anti-corrosive property.Finally,the effects of different PVC solvents,curing accelerators and different silane coupling agents on the application performance,drying performance and anti-corrosion performance of the coating were analyzed.
