Carcinogenic: NTP, IARC, OSHA, ACGIH: No component of this product present at levels
greater than or equal to 0.1% is identified as a known or anticipated carcinogen. Formaldehyde is
identified by the NTP, IARC, and OSHA as a carcinogen. Specifically, formaldehyde causes can-
cer in the nasal and sinus cavities. Formaldehyde is also considered a respiratory sensitizer.

USE & PERFORMANCE
Outstanding properties: Provides very good matting. Provides homogeneous and reproducible sur-
face structure effects, and soft feel effect and matting properties. Improved anti-slip properties.
Enhances scratch resistance and improves anti-blocking properties. It has no effect on viscosity
and surface slip and does not have a foam stabilizing effect. In leather coatings, it improves anti-
blocking, matting, and the soft-feel effect. Improves the orientation of silica matting agents.
Improves slip, abrasion and rub resistance in aqueous coatings and inks. Offers excellent heat sta-
bility, chemical resistance, and hardness. Improves the sanding of the coating in floor varnishes.
Better recoatability compared to micronized waxes based on polyethylene or polypropylene. It
produces a durable, semigloss finish when used either alone or with silica. It retards the settling of
pigments and fillers and assists in their redispersion. Offers best mar resistance and anti-blocking.
Due to the high price of pure PTFE-powders these products can be used only in a small range of
applications.
Recommended for polymers: polyester/epoxy, acrylate, PU, epoxy, PVC rigid and flexible
Recommended for products: architectural, industrial, wood and furniture coatings, leather coatings,
printing inks, overprint varnishes, lacquers, parquet lacquers
