Question 1

What coefficient of friction is achievable with PTFE PM-5 in a coating film?

Accepted Answer

At loadings of 1–2 wt%, PTFE PM-5 reduces the dynamic coefficient of friction to below 0.05. The ultra-fine 5 µm particle size ensures uniform distribution in thin films without surface roughness, delivering consistent slip and anti-wear performance across coatings and inks.

Question 2

How should PTFE PM-5 be dispersed into a waterborne coating system?

Accepted Answer

Pre-disperse PTFE PM-5 in a portion of the aqueous binder or deionized water using high-speed dispersion at 3,000–5,000 rpm before letdown. Including a non-ionic wetting agent at 0.1–0.3% on PTFE weight improves wettability and prevents reagglomeration during storage.

Question 3

Is PTFE PM-5 chemically reactive in UV-curable acrylate ink systems?

Accepted Answer

No. PTFE PM-5 is chemically inert and does not participate in radical or cationic cure reactions. Add it after pigment grind and before UV monomer addition. Because PTFE is denser than most acrylate oligomers, ensure adequate viscosity or thixotropy in the formulation to prevent settling before UV cure.
