The subsequent discussion focuses on the dynamic mechanical properties of the waterborne epoxy cured films and the low-temperature film-forming capabilities of the waterborne epoxy varnishes; it is concluded with an assessment of the application performance of the waterborne epoxy metal primers.
3、Tongde Epoxy Curing Agent 3EC164W
The 3EC164W epoxy curing agent is a high-performance liquid curing agent suitable for various epoxy resin systems, including bisphenol A (EPDM) and polyisocyanate (PDI) types.
4、Preliminary Results on Preparation and Performance of a Self
Water-based epoxy resin and water-based epoxy curing agent were the two essential components of a water-based epoxy system. The ultimate performance of the cured film was determined by their structure and the effectiveness of the curing process.
Synthesis and properties of a nonionic water
Water-based epoxy curing agents can be divided into two categories: type I and type II. Type I epoxy systems require their curing agents to have the functions of curing and emulsifying. The epoxy resin is a liquid or emulsion, and the curing agent is a water-soluble amine curing agent.
Synthesis of a self‐emulsifiable waterborne epoxy curing agent
The cured film prepared by the self-emulsifiable curing agent and epoxy resin under the optimal mass ratio displayed good thermal property, hardness, toughness, adhesion, and corrosion...
Journal of Applied Polymer Science
Most waterborne epoxy resin emulsifiers are inactive, and the free emulsifier will precipitate out during the curing of the coating film, which will seriously affect the water resistance, solvent resistance, and hardness of the coating film.
Research Progress in Waterborne Epoxy Resin Curing Agent
The effect of the compatibility and reactivity of waterborne epoxy curing agents on the curing films and its control methods were also discussed，which provided guidance for selection of suitable curing agents and development of waterborne epoxy curing agent with excellent performance.
