Chemours (formerly DuPont) Teflon™ PTFE DISP 30 (previously known as TE3859) is a milky white aqueous PTFE dispersion stabilized with a non-ionic surfactant.  It is a general purpose product, often preferred for coating and impregnating woven goods and for some coating processes.  It imparts properties unique to PTFE resin to porous structures, as well as to base materials when used as an additive.  When properly processed, the PTFE resin in DISP 30 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).

• 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

• 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
• Anti-drip additive for plastics
• Binder for battery anode or cathode matrices

Please note that dispersions contain solvents that may compromise the seals of the bottles if the solvents are left in direct contact with the lids for long periods of time. We recommend always storing the bottles in an upright orientation as soon as the shipment is received to lessen the likelihood of inadvertent leakage.  Due to settling issues, the material must be gently rolled in the storage container 1-2 times per month to maintain the suspension.  High shear actions will cause the material to fall out of suspension.
