High temperature resistant powder coating is resource-saving, energy-saving, pollution-free, high labor productivity, and easier to implement automatic coating.High temperature resistant powder coating High temperature resistant powder coating and its preparation method, high temperature resistant powder coating, the mass fraction of its various components is: modified silicone resin 40%-55%, curing agent 2%-3%, high temperature filler 40%-48%, Additives 1%-2%, high temperature pigments 0.
High temperature resistant powder coatings are synthesized by a variety of polymer material modified resins, high temperature resistant pigments, organic fillers, inorganic fillers and additives with special functions.. Because the N atom of the chlorine group on the molecular chain easily forms hydrogen bonds with the hydrogen atoms on the adjacent segment, the melting point of polyamide resin is generally higher.
In addition, because the polyester resin has polar groups, the powdering rate is higher than that of epoxy resin. Disadvantages: uneven powder on edges and corners, difficult to cover up film defects after curing, and high curing conditions. The biggest advantage of thermosetting acrylic resin powder coating is that it has excellent weather resistance, color retention, pollution resistance, strong metal adhesion, and excellent film appearance.
Polyvinyl chloride powder is one China bonding powder coatings Manufacturers of the cheapest polymers produced on a large scale industrially. 2. Thermosetting powder coatings include epoxy resin, polyester, and acrylic resin.
Therefore, the development of thermosetting powder coatings is particularly rapid.5 Latex powder coating Latex powder is prepared by spray drying the emulsion, most of which are vinyl acetate copolymers. The disadvantage is that the mechanical strength is not high, and the adhesion to the substrate is poor.
