SAE AMS3140B – Coating, Urethane, Aliphatic Isocyanate Polytetrafluoroethylene Filled (Stabilized: Jul 2013)

This document has been declared “Stabilized” and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.

This specification has been declared “NONCURRENT” by the Aerospace Materials Division, SAE, as of October, 2007. It is recommended, therefore, that this specification not be specified fro new designs. “NONCURRENT” refers to those specifications which have previously been widely used and which may be required for production or processing of existing designs in the future. The Aerospace Materials Division, however, does not recommend these specificaitons for future use in new designs.

This specification covers a two-component, polytetrafluoroethylene filled polyurethane coating material supplied in kit form. Primarily for use on surfaces where a low-friction coating having exceptional abrasion, impact, and chemical resistance is required for general service within the range -55 to +120\mDC (-65 to +250\mDF) with intermittent exposure up to 165\mDC (325\mDF).
