                                            Chinese name:Acrylic powder coating
                                             
                                            composition
                                             
                                            The acrylic powder coating is composed of an acrylic resin, a pigment filler, an additive, a curing agent and the like.
                                             
                                            species
                                             
                                            Since the functional groups contained in the molecular structure are different, the acrylic resin has the following types:
                                            1. An acrylic resin containing a glycidyl ether functional group.
                                            2. Acrylic resin containing a hydroxyl functional group.
                                            3. Acrylic resin containing a hydroxyl functional group.
                                             
                                            Curing form and film properties
                                             
                                            Due to the structure of the acrylic resin and the functional groups contained therein, the curing agent and curing mechanism used are different. After cross-linking, the physicochemical properties are also different.
                                            The curing conditions of the acrylic powder are: the cured form and characteristics of the acrylic powder coating. The cured form and characteristics of the acrylic powder coating.
                                            Curing temperature: 180 ° C ~ 200 ° C;
                                            Curing time: 15min~20min;
                                            The construction method of the thermosetting powder coating can be applied to the acrylic powder coating.
                                            The curing form and characteristics of acrylic powder coating are shown in Figure 1 on the right.
                                             
                                            Production process
                                             
                                            There are four production methods for acrylic powder coatings: evaporation. The second is spray drying. The third is wet. Finally, it is the same as the epoxy powder coating production method. The fourth production method is mainly used. The process is as follows:
                                            Mixing→Extrusion→Crushing→Screening→Packaging
                                             
                                            performance
                                             
                                            The performance of acrylic powder coatings varies with different curing agents.
                                            Different curing agents and performance comparison of different curing agents and performance comparison
