The roles of PTFE micropowder in coatings and inks primarily include enhancing the scratch resistance, wear resistance, and anti-sticking properties of coatings, reducing the friction coefficient, improving gloss and lubricity, as well as strengthening chemical corrosion resistance and weatherability.
Roles in Coatings:
Enhancing Scratch Resistance and Wear Properties: PTFE micropowder can significantly improve the scratch resistance, wear resistance, and anti-sticking properties of coatings, enabling them to perform well under high-temperature and chemically corrosive environments.
Reducing the Friction Coefficient: As a self-lubricant, PTFE micropowder effectively reduces the product's friction coefficient, minimizing wear and friction.
Improving Gloss and Lubricity: PTFE micropowder enhances the gloss and lubricity of coatings, resulting in a smoother surface and a better tactile feel.
Strengthening Chemical Corrosion Resistance and Weatherability: PTFE micropowder possesses good chemical resistance and weatherability, maintaining the stability and durability of coatings in harsh environments.
Roles in Inks:
Enhancing Wear Resistance and Lubricity: As an anti-wear agent, PTFE micropowder improves the wear resistance and lubricity of inks, reducing mechanical blockages during the printing process.
Improving Gloss and Surface Smoothness: PTFE micropowder enhances the gloss and surface smoothness of inks, making printed materials more aesthetically pleasing.
Reducing Mechanical Blockages During Printing: By adding PTFE micropowder, blockage issues of inks during the printing process can be reduced, thereby improving printing efficiency.
The recommended addition ratio of PTFE micropowder in coatings and inks typically ranges from approximately 0.5% to 5% (by weight). However, please adhere to actual application requirements.
