440-R® SMT Detergent

440-R® SMT Detergent is the only stencil-cleaning chemistry verified by the U.S. EPA for specific parameters of Environmental Safety, user safety and cleaning efficiency and is the only stencil-cleaning chemistry to “survive the test of time”. 440-R SMT Detergent was introduced in 1990 and is the only chemistry able to clean all solder pastes used in SMT assembly.

For use in all aqueous stencil cleaner machines, spray-in-air, ultrasonic and spray-under-immersion.* Smart Sonic’s 440-R SMT Detergent eliminates unpleasant odors, solvent vapors and VOCs, shortens cleaning cycles, and cleans at low temperature to conserve energy and protect stencils. Winner of the SMT Vision Award and Global Technology Award for Best Cleaning Chemistry.
