ResinTech PX-A75-OH is a weak base macroporous catalyst with large porous polymeric structure that allows aqueous and non aqueous catalytic reactions inside of the its sponge-like structure. Its unique structure allows the complete reaction molecular within the resin bead with its hydroxyl available groups for a complete reaction. ResinTech PX-A75-OH has been designed as a fast reaction catalytic media for mineral and organic acids neutralization from aldehydes solutions, such formaldehyde. Because of its large polymeric macroporous structure the PX-A75-OH can easely neutralize formic acid content in formaldehyde solutions. In its dry version, the PX-A75-OH-D can be used as organophosphate and pyrethroid insecticides scavenging media from volatile oils.

  • Acid neutralization from polar and non polar solutions

  • Chromic acid neutralization and recovery from plating rinse water

  • Insecticides scavenging from volatile oils (Dry version)
