Product Overview

BONDERITE® S-FN T-502 ACHESON (also known as Emralon TM-001A) is a lubricant coating that combines specially processed carbon particles in a fluoroelastomer resin system. This product delivers high resistance values to effectively dissipate heat and handle high voltages, making it ideally suited for electrical applications. BONDERITE® S-FN T-502 ACHESON remains flexible over a wide temperature range of -40°C to over 260°C, allowing for a smooth dry film that is free of cracks. The smooth film provides more controlled electrical performance, reducing scrap and rework. The coating's innate flexibility ensures it maintains its performance characteristics even under extreme conditions, offering reliability in both high-stress and delicate applications. Additionally, BONDERITE® S-FN T-502 ACHESON is solvent-based, creating a fast-drying and curing system that reduces energy costs, increases production rates, and improves productivity. Furthermore, this product can be mixed with other BONDERITE® products to provide a wider resistance range. BONDERITE® S-FN T-502 ACHESON is compatible with most common solvents and substrates, including metal, plastic, and rubber. This compatibility not only ensures a broad spectrum of resistance options but also allows users to tailor solutions specific to their needs. The use of fluoroelastomer resin also contributes to the product's moisture and chemical resistance, making it a durable option in challenging environments. By incorporating this product into their designs, engineers and manufacturers can enhance the longevity and efficiency of electrical components, ensuring optimal performance and fewer maintenance demands over time.

BONDERITE® S-FN T-502 ACHESON is supplied ready-for-use for brush applications. Dipping and spraying may require dilution with methyl ethyl ketone (MEK) solvent. The electrical resistance can by adjusted by controlling the film thickness.
