ResinTech PX-A75-OH is a weak base macroporous catalyst designed for aqueous and non-aqueous catalytic reactions within its structure. It is particularly effective for neutralizing mineral and organic acids, including formic acid in formaldehyde solutions. In its dry version (PX-A75-OH-D), it can be used for scavenging organophosphate and pyrethroid insecticides from volatile oils.

Suggested Operating Conditions

• Maximum operating temperature: 140˚F
• Maximum Pressure Loss: 15 psi across resin bed
• Minimum Depth: 24 inches
• Service Flow Rate: 0.5 - 5.0 bed volumes/hour
