Varsal’s MSA process is clean with no methyl mercaptan odor, and our process conditions do not typically allow formation of methyl esters. It is approved for use in all major tin-lead applications, and low oxidizables and chlorides ensure long life, stable solder deposits. Varsal’s clean process promotes “Green Chemistry” with less environmental impact from sludge. It also provides superior throwing power to allow high-speed tin-lead alloy plating in reel-to-reel operations.
