Question 1

At what dosage level should Micronized PTFE Powder PM-5 be added to a coating formulation?

Accepted Answer

Typical addition levels are 0.5–3.0% by weight of the total formulation. Higher loadings (up to 5%) can be used for applications demanding maximum abrasion resistance or release, but may affect gloss. PM-5 is best dispersed using high-speed dissolution or a pearl mill to prevent agglomeration.

Question 2

Is PM-5 compatible with both solventborne and waterborne systems?

Accepted Answer

Yes. PM-5 is chemically inert and compatible with virtually all resin and solvent systems including waterborne acrylics, solventborne alkyds, UV-curable resins, and nitrocellulose ink vehicles. A wetting dispersant is recommended in waterborne systems to achieve uniform dispersion.

Question 3

How does the D50 of 5 µm affect surface appearance compared to coarser PTFE grades?

Accepted Answer

The fine 5 µm median particle size minimises gloss reduction and haze, making PM-5 suitable for semi-gloss and high-gloss finishes where coarser grades (D50 ≥10 µm) would cause unacceptable matting or surface texture. It also improves film uniformity and reduces settling tendency in storage.
