Important Acid Catalyst Information Important Acid Acid Catalyst Catalyst Information Information Important Important Acid Catalyst Information The PD2K MC3000 and MC4000 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.
