The Role Of PTFE Wax In Coatings

The role of polytetrafluoroethylene wax in coatings, PTFE micropowder can be used as a modifier for synthetic materials, almost all engineering plastics with improved lubricating properties are mixed with PTFE ultrafine micropowder or micropowder.

Polytetrafluoroethylene wax for engineering plastics: in polyamide (PA), polyacetal (POM), polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), nylon Adding 5%-25% PTFE micropowder to (PA), polyethylene (PE) and other high-performance engineering resins can significantly improve the wear, friction and viscous sliding properties of parts made of these materials. It is used to manufacture wheels, bearings and pulleys, etc. It can also be used to replace lubricating metal parts, reducing the weight of parts and reducing maintenance costs.

Application in coatings: for the application of coatings on the surface of aluminum coils and non-stick pan coatings. Reduce friction coefficient, solve surface scratch resistance, wear resistance and other properties.

In terms of printing inks: PTFE micropowder is used as an additive to add offset printing, gravure printing, and flexographic printing inks. The general dosage is 0.1%-3% of the solid, which can significantly improve the sliding property, surface smoothness, gloss of the ink, and make the printed product friction-resistant. PTFE micropowder can also reduce clogging, which is suitable for the needs of fast printers. And can effectively avoid paper sticking.

PTFE modified polyolefin wax has good friction resistance, high scratch resistance, smoothness and texture. The wax powder contains polytetrafluorowax, because it cannot be melted, it protrudes on the surface as a single particle, which becomes the first line of defense against abrasion, thereby prolonging the wear-resistant time, and when the coating film cools, the polytetrafluoroethylene Olefin wax precipitates from the coating solution, forms fine particles, floats on the surface of the coating film, plays a role of smoothness and scratch resistance, and becomes the second line of defense against abrasion. The best combination of PTFE and polyethylene The combination has the advantages of the two wax powders, and the hardening effect is the best.
