mju:wax 2739 wax powder introduction

2021-12-21   Pageview:259

The mju:wax series 2739 grade from the European wax powder brand CeroNas, mixed with PE, Brazilian carnauba wax and PTFE PTFE wax at the same time, has both scratch and abrasion resistance, metal scratch resistance, and provides high slip performance, which helps a lot in can coatings, and can effectively reduce the coefficient of friction, reduce adhesion, etc.

Besides using in can coating, it can also be used in the field of UV ink, which can play a hazy effect and has a very characteristic performance compared with similar products, welcome to try the sample.

This PE/PTFE mixed wax powder can also be used in water-based system and solvent-based system, without VOC, in accordance with European regulations.

 

 

 

 

 

 

 

 

 

 

 

 

Ethylene-chlorotrifluoroethylene polymer resin and powder coatings can be coated by fluidized bed dip coating, electrostatic powder spraying and other methods. In electrostatic powder coating, the workpiece is generally preheated to about 240~270℃, and the coating film thickness of 0.13~0.76mm can be obtained by changing the preheating temperature; in the fluidized bed dip coating process, the workpiece is preheated to 240℃ and immersed Apply for 1~2s, then bake, melt and level, if you need to dip the coating for 2~4s when the coating is thick, it is suitable for the coating of small and complex parts. This coating has very good corrosion resistance to most inorganic and organic chemicals and organic solvents.

So far, there is no solvent that can etch or crack this kind of coating below 120°C; this kind of coating has good corrosion resistance to chlorine and chlorine derivatives at high temperatures. The performance of this coating is very good. It does not need to add ultraviolet absorbers, heat stabilizers, plasticizers, lubricants and flame retardants in the formulation. Examples of applications in industrial production are:
①Cleaning with chlorine The sheet lining on the tower is intact for 6 years;
②The hydrofluoric acid delivery pipeline is intact for 2 years;
③The sodium hypochlorite treatment system is intact for more than 2 years.
In my country, Dalian Zhenbang Fluorine Coating Co., Ltd. has developed ethylene-trifluorooxyethylene copolymer resin for powder coatings and formulated corresponding thermoplastic powder coatings.

This polymer is a compound synthesized by ethylene and chlorotrifluoroethylene under the conditions of high temperature and high pressure in Freon and deoxyionized water solvent, under the action of initiator and chain transfer agent, the Freon solvent is removed by distillation, and deionization is added under stirring. The water is filtered to obtain the resin, which is then dried and pulverized to obtain the product. In the synthesis, the monomer ratio, solvent ratio, reaction temperature, and reaction pressure have a great influence on the yield and performance of the product.

Because of the high melting point of this resin, it is difficult to extrude and mix with other materials by the melt extrusion method, and the molecule is the largest, the hardness is high, and the toughness is strong. It cannot be crushed by the general crushing method, so it is difficult to use ordinary Method to manufacture powder coatings, it is best to use the freezing crushing process. The company formulated ethylene-chlorotrifluoroethylene copolymer resin powder coatings by dry mixing of resins, pigments, fillers and wax additives. Before powder preparation, the fluororesin was pulverized to an average particle size of less than 45pm using special micro-pulverization equipment. Use ethylene trifluorochloroethylene copolymer to formulate powder coating formulations and coating properties; the influence of different ethylene-chlorotrifluoroethylene copolymer powder coating formulations and melt index on the appearance of the coating; ethylene-chlorotrifluoroethylene copolymer powder coatings Film resistance to chemicals.
