Miller-Stephenson MS-242N-AS (14-oz-Aero)

Additional Product Information

Overview

MS-242N-AS Antistatic Quik-Freeze® is a nonflammable aerosol freeze spray designed to rapidly cool electronic components to -40°F (-40°C) for diagnostic and maintenance purposes. Widely used in aviation maintenance, repair, and overhaul (MRO) environments, it enables technicians to quickly identify intermittent electronic faults without damaging properly functioning components. Aviation teams rely on it for precise thermal stress testing, component protection during soldering, and safe, residue-free operation in sensitive aircraft electronic systems.
