Self-leveling epoxy coating introduction Character LCD Modules

Clean-resistant epoxy self-leveling epoxy floor coating is a coating film-forming material, and then by adding a curing agent, non-volatile reactive diluents, additives and pigments and fillers preparation of a solvent-free high performance coatings. Epoxy self-leveling coating film forming process is a chemical method, first the soluble low molecular weight epoxy resin is coated on the substrate surface, graphic lcd modules leaving the reaction between molecules to further increase the molecular weight or the formation of crosslinking tough film. Where the optional requirement epoxy resin can be at room temperature deposition, and the coating film is required to have a viscosity relay, strong mechanical strength, chemical resistance and good electrical properties.
Comparison of domestic self-leveling coatings
Coating after the construction can achieve smooth feature called leveling, leveling coating applications is a very important issue, and it affects the apparent gloss coating, when the paint brush to the substrate, will leave brush marks, this brush marks may be due to the flow of paint dried before mitigated. When the coating is poor leveling, can be seen with the naked eye in the case uneven coating. When the difference to the naked eye can not see, at this time, said the film is flat, Graphic LCD Display smooth coating to the uneven gravity is not the driving force, but the surface tension, under normal circumstances, leveling can be used ORCHARD formula evaluation. Theoretically, the lower the viscosity paint or coating the thicker the better leveling. Because self-leveling coatings particularity, the general requirements of the film after the film has good leveling, while simultaneously maintaining good surface properties. Throughout the current domestic and self-leveling epoxy material system, there are two main technical guiding ideology, one of many domestic manufacturers generally use the guiding ideology (A class), A class technology theme is: the use of an appropriate amount of solvent to achieve Good leveling coating, the coating process, the coating of filler will gradually decline, the cured film has good leveling, but the surface hardness, wear resistance is poor, while in the construction may be will produce more spots such as lack of surface flaw, which is one-sided pursuit of leveling results; Second, foreign technology and many other manufacturers follow (B class), while class B self-leveling resin coating is to ensure good leveling while still maintaining the uniformity of the filler, the cured coating film so as to ensure better apparent decorative.
