Epoxy diluent is mainly used to reduce the viscosity of epoxy adhesive system, dissolve, disperse and dilute coatings, and improve the coating and fluidity of glue solution. Diluents also play a role in prolonging the service life. There are many classification methods of diluents. According to their use mechanism, they can be divided into two categories: inactive diluents and active diluents. Epoxy resin diluent is mixed with basic resin, which can reduce the viscosity of curing system, increase fluidity, prolong service life and facilitate large-area construction; The operability is improved without affecting the basic properties of the cured product. Convenient for casting, pouring, bonding, sealing, impregnation and other applications.
