ENVIRA® E-647 is a crosslinked, moderate molecular weight cationic polymer based on an aqueous solution of polyquaternary ammonium chloride. ENVIRA® E-647 is fully water-soluble and functions as an effective coagulant in a variety of applications. ENVIRA® E-647 is designed to satisfy the types of cationic demand found in paper making systems. In these systems ENVIRA® E-647 aids in retention of fillers and fines, dyes, synthetic and rosin size. In addition, the high cationic charge of ENVIRA® E-647 makes it a good candidate for use with high molecular weight anionic or cationic retention aids.
