Poor surface smoothness, low gloss, and microscopic pinholes may occur during the spraying and baking of waterborne PTFE non-stick coatings.

These defects can allow steam, fats, and corrosive substances to penetrate the coating over time, increasing the risk of blistering, peeling, and reduced non-stick performance.

Why Pinholes May Form

Pure PTFE has extremely high melt viscosity and limited flow during curing, which may leave microscopic voids or pinholes in the finished coating.

Adding PFA 001 Modified Concentrated Dispersion can improve melt flow and produce a smoother, denser PTFE coating without significantly increasing formulation costs.

Key Properties and Benefits

Improved Melt Flow at High Temperatures: PFA 001 has good melt processability during curing. It flows into microscopic gaps between PTFE particles, helping reduce pinholes and form a dense, uniform layer.

Controlled Melting Point (305 ± 10°C): According to DSC testing, PFA 001 melts at a lower temperature than standard PTFE. This allows earlier melt-bonding and improves film density.

Compatibility with Waterborne Formulations:

Solid Content: 48–52% (Typical: 51%)

Surfactant: 7–9% (Typical: 7.5%)

pH Value: 8–10 (Typical: 9)

PFA 001 maintains good dispersion stability when properly incorporated into compatible waterborne non-stick coating formulations.

Storage & Handling Guidelines

Store PFA 001 between 5°C and 30°C and protect it from freezing. Stir gently at regular intervals to maintain uniformity. Avoid high-speed mixing, excessive shear, and foaming.

Refer to the latest SDS for complete safety and handling information.

FAQ

1. How does PFA 001 reduce pinholes in PTFE coatings?

It improves melt flow during curing, allowing the coating to form a smoother and denser film.

2. How much PFA 001 should be used?

The dosage depends on the PTFE formulation, film thickness, and surface requirements. Contact us for a recommended starting dosage.

3. Is PFA 001 suitable for waterborne PTFE coatings?

Yes. It is supplied as a waterborne dispersion. Compatibility should still be checked in the final formulation before production.

4. Does PFA 001 change the baking conditions?

PFA 001 melts earlier than standard PTFE, but the final baking temperature and time should be set according to the complete coating system.

5. Can I request a sample?

Yes. A free sample and TDS are available for laboratory evaluation.
