Teflon® PTFE DISP 33

About
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 excellent weatherability 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.&&
