Description Teflon S 958-303 and Teflon S 958-313 are onecoat, solvent-based coatings specially formulated to provide a tough, durable film for dry lubrication, with excellent salt spray resistance. In addition, Teflon S 958-313 has exceptionally good abrasion resistance. They can be cured at temperatures as low as 177?C (350?F). Refer to Table 1 for physical property data. FDA Status Teflon S 958-303 and Teflon S 958-313 do not comply with FDA regulations governing components of coatings for direct food contact.

Surface Preparation For aluminum, stainless steel, and carbon steel: 1. Clean (vapor degrease, prebake, or other). 2. Lightly grit-blast with aluminum oxide. For carbon steel, a zinc or manganese phosphate conversion coating should be applied after grit-blast. These products also adhere well to most hard anodized aluminum surfaces. Application 1. Bring coating to room temperature. Shake or agitate to reincorporate any settled material. 2. Product is supplied ready-to-spray. If thinning is desired, add a small amount of TN-8718 (n-methyl pyrrolidone NMP) with steady mixing. If faster evaporation is needed use TN-8595 or a 50:50 mixture of NMP:MIBK with care. This thinner must be added slowly with constant stirring. 3. Use conventional industrial spray equipment. 4. Recommended film thickness is 15–20 μm (0.6–0.8 mil). The heavier film build will improve salt spray corrosion resistance. Baking Note: All temperatures refer to metal temperature. 1. Flash or force dry for 5 min. 2. Recommended bake for 15 min at 343?C (650?F). These products can be cured at temperatures as low as 177?C (350?F) by extending the cure time. However, the toughness and durability of the coating decreases as the cure temperature is reduced below 343?C (650?F). The color will change at the higher bakes to a brown cast, but performance will not be affected. Fact Sheet Teflon S Coatings 958-303 and 958-313 DuPont? Teflon Industrial Coatings The DuPont Oval Logo, The miracles of science, and Teflon are trademarks or registered trademarks of E.I. du Pont de Nemours and Company. Use of DuPont trademarks is subject to License Agreement and qualification. Storage and Stability Teflon S 958-303 is stable for at least 18 months when stored at normal room temperature of 18–24?C (65–75?F). Teflon S 958-313 is stable for at least 12 months when stored at normal room temperature of 18–24?C (65–75?F). Safety Follow normal industrial safety practices for handling and applying Teflon products. Industrial experience has clearly shown Teflon materials can be processed and used at elevated temperatures without hazard providing adequate ventilation is used. Ventilation should be available at baking temperatures 275?C (525?F) and above. Before using Teflon S, read the Material Safety Data Sheet (MSDS) and the detailed information in the “Guide to the Safe Handling of Fluoropolymer Resins,” latest edition, published by the Fluoro-polymers Division of The Society of the Plastics Industry. When grit-blasting Teflon finishes off aluminum or magnesium surfaces, the possibility of explosion exists if the fines are allowed to become heated. Good housekeeping practices, keeping the residue wet, and keeping the ventilation and dust collection systems in good working order reduces this risk.
