DuPont™ Teflon ® PTFE DISP 33 is a milky white aqueous PTFE dispersion stabilized with a non-ionic surfactant. DISP 33 is typically used to coat woven glass cloth and has been especially formulated to provide void-free coatings with enhanced surface smoothness, adhesion, gloss and weldability. When properly processed, the PTFE resin in DISP 33 exhibits the superior properties typical of the fluoropolymer resin: retention of
properties after service at 260 °C (500 °F), and useful properties at -240 °C (-400 °F).
DISP 33 aqueous dispersion provides:
- enhanced surface smoothness, adhesion, gloss and weldability
- inertness to nearly all industrial chemicals and solvents
- stability at high temperatures
- excellent dielectric properties
- lowest coefficient of friction of any solid material
- non-stick characteristics
Typical Applications
- Coated woven fiber-glass fabric used in architectural, high-performance industrial, food processing and electronics applications
- Impregnated packing made from braided fibers for severe chemical and thermal service
- Cast film for capacitor dielectrics or chemical barriers
- Surface coatings for metallic or other high-temperature substrates
Teflon ® PTFE DISP 33 meets the requirements of ASTM D 4441-04, type II, grade 6, class A.
