  • Page 11: Important Acid Catalyst Information

    Important Acid Catalyst Information Important Acid Catalyst Information The 2KS Plural Component Proportioner is designed for acid catalysts (“acid”) currently used in two-component, wood-finishing materials. Current acids in use (with pH levels as low as 1) are more corrosive than earlier acids. More corrosion-resistant wetted materials of construction are required, and must be used without substitution, to withstand the increased corrosive properties of these acids.
