Hunan University develops a fast drying room temperature curing waterborne epoxy resin curing agent

December 30, 2011

[China paint information] Hunan University has developed a fast drying room temperature curing waterborne epoxy resin curing agent. The curing agent can be applied to water-based coatings and water-based adhesives, such as floor coatings, industrial anti-corrosion 1, protective coatings before experiments, furniture adhesives, etc. The R & D personnel first mix liquid epoxy resin, double ended epoxy polyether or the mixture of double ended epoxy polyether and single ended epoxy polyether with bisphenol compounds under the catalyst at 150 ~ 200 ℃ to produce intermediate products, and then the intermediate (7) implement industrial innovation and development service organization culture engineering products and amine reactions, and then vacuum distillation will produce clogged valve holes For very serious consequences such as scratching the piston surface, remove the excess amine and solvent, and finally cool the resin to 60 ~ 90 ℃ and drop deionized water to obtain a fast drying room temperature curing waterborne epoxy resin curing agent with amber or light yellow appearance. The curing agent has simple production process, short surface drying time and long application period when curing epoxy resin lotion. In addition, the epoxy resin film cured by the curing agent has excellent performance
