Water-based epoxy curing agent floor paint is a coating composed of epoxy resin and curing agent. When preparing water-based epoxy floor coatings, the choice of curing agent is crucial. Water-based epoxy coatings are multi-phase systems, with the epoxy resin as the dispersed phase and the curing agent as the continuous phase. The curing process of water-based epoxy flooring is mainly controlled by diffusion. The curing reaction first occurs at the interface. The viscosity of the surface layer of the epoxy particles will gradually increase. At the same time, the curing agent gradually diffuses into the epoxy resin, further solidifying the epoxy resin. When the particle size of the epoxy emulsion is smaller, the curing is closer to complete. Choosing a curing agent with good performance will have better compatibility with epoxy resin and will diffuse into the epoxy floor more easily, thus facilitating curing. Currently commonly used water-based curing agents include fatty amine adducts, polyamides, etc.
In addition, when used as a curing agent for epoxy-based reactions, epoxy flooring with a high epoxy value will have a large effective cross-linking density after full curing. It has strong resistance to corrosive media passing through the coating film.
The role of water-based epoxy curing agent:
Three functions: one is to react the amine group with the epoxy group to solidify the epoxy resin; the other is to emulsify the epoxy resin into a small liquid The droplets are dispersed in the water; another function is to penetrate the epoxy resin droplets and fully fuse and solidify. Suzhou Meiguowang Floor Materials Co., Ltd. currently promotes the latest generation of non-ionic self-emulsifying types. This type of product is highly compatible with other ionic products, compatible with different acid and alkali pigments and fillers, and compatible with cement.
The role of water-based epoxy curing agent in floor paint
1. The water-based epoxy curing agent epoxy surface can repair unsatisfactory areas such as the base paint and mid-coat paint. If there is any need to be re-sealed and repaired, Epoxy topcoat can be used at any time.
2. Don’t underestimate the role of epoxy topcoat. Epoxy topcoat can determine the aesthetics of water-based epoxy curing agent floor paint. Epoxy topcoat Topcoat plays an important role.
3. The epoxy topcoat can enhance the hardness of the entire ground during the construction of water-based epoxy curing agent floor coatings, which can make the epoxy floor Increases greater wear resistance and scratch resistance.
