SBS Tech Grade

Technical Grade Acidifier

Efficacy Across Technical Applications

Technical grade Sodium Bisulfate (SBS Tech Grade) is a dry, water soluble, non-hazardous acid that reduces pH in diverse technical applications such as pools and spas, water treatment systems, metal finishing, cleaning compounds and more. It is manufactured using systems certified to ISO 9001:2015 standards without the use of crude oil and it contains no chlorine, fluorine or organic compounds.

Over 30 years of research both independently and in partnership with end users, we have learned that the true value of SBS Tech Grade goes beyond just lowering pH.
