Characteristics And Uses Of Polytetrafluoroethylene Wax Micropowder

Characteristics and uses of polytetrafluoroethylene wax micropowder. It is a PE/PTFE compound micropowder wax with high hardness. The addition of PTFE greatly improves the slippery and scratch resistance of polytetrafluoroethylene wax micropowder, resulting in very good results. synergy effect.

The powder has high hardness, good particle shape and a relatively concentrated particle size range, with regular molecular weight, easy dispersion and good wear resistance.

1. Paints and coatings:
PTFE wax powder can be used as an additive in coatings to improve its release performance, surface abrasion resistance, lubricity, chemical resistance, weather resistance and water resistance. It can also be used to improve the surface structure and gloss of paints and coatings. PTFE wax micropowder can be used in paints for utensils, plastics, industries, etc. to provide good hand feel and scratch resistance.

2. Ink:
PTFE wax powder can be used as an anti-wear agent in inks, which can improve wear resistance, lubricity, surface gloss, and can also improve agglomeration and gloss. It can be used in various inks such as silk screen, gravure, internal printing, surface printing, etc. It has the functions of anti-sedimentation, anti-adhesion, anti-scratch, anti-sticking and anti-friction, while providing a smooth and soft touch and more durable Good hydrophobicity and sealing properties.

3. Oils and greases:
PTFE wax powder is an ideal additive for high-temperature lubricants in oils and greases. Can be added to high viscosity special lubricants (perfluoropolyether oil, silicone, fluorosilicone, hydrocarbon lubricants). It can improve the service life and lubrication performance of lubricants, especially in high temperature and corrosive environments.

4. Powder coating:
Can be used in powder coatings to improve surface hardness, slipperiness, friction resistance, and have a certain matting effect.

TIANSHI engineers recommend the amount of polytetrafluoroethylene wax micropowder to be added (specifically, it is recommended that you pass the test):
1. In different systems, the amount of wax powder added is generally between 0.5-3%.
2. It can usually be directly dispersed in solvent-based coatings and inks through high-speed stirring.
3. It can be added through various grinders and high-shear dispersing equipment. When using the grinder, pay attention to controlling the grinding temperature.
4. Pre-dispersion treatment can be carried out to prepare a wax slurry with a wax powder concentration of 20-30%, and added to the system when needed, which can reduce the dispersion time of the wax powder.
