Ultraflon DF series products are premium PTFE dispersions based on an ultra-high purity Isopropyl Alcohol (IPA) carrier. The solids content of DF-20A is 25%. This colloidal dispersion contains a proprietary additive to improve adhesion to substrates such as glass, plastic, and metal. The primary particles of PTFE have a nanometric particle size, and are engineered to have a spherical morphology. The dispersion has an exacting, narrow particle size distribution, which translates into consistent, uniform properties. DF-20A is not made with the PFOA surfactant. The resulting film formation from DF-20A may be considered semi-permanent due to the proprietary adhesion-promoting chemistry.
