TinMS 400 DA20

DA-20, the latest tin product from Innochem, is a source of highly concentrated stannous methane sulfonate. Common generic tin methane sulfonate contains elevated levels of free methane sulfonic acid (MSA) resulting in acid growth within the electrolyte during the plating operation. 

Product-TinMS400 DA20

To maintain process efficiency it is therefore necessary to dilute the plating solution and add tin to return to optimum plating parameters. The use of DA-20 prevents acid build up from tin concentrate additions and removes excess free acid developed in the course of the plating operation.
