Cationic Rosin

OPL Cationic Rosin – Product Overview:

Cationic rosin emulsion is an effective sizing agent for paper. An acid-fortified rosin (i.e. rosin fortified with Maleic Anhydride) is reacted with a water soluble salt of alkylene-acrylic acid copolymer to form a rosin soap. The rosin soap is emulsified with water under high shearing conditions to provide a modified cationic rosin emulsion.

Benefits of OPL Cationic Rosin:

1. Reduces Cost of Paper Making - Cationic Rosin reduces the consumption of additives like Alum (Aluminium Sulfate) thus lowering the cost of paper making.

2. Improves Quality of Paper - Lowering the consumption of Alum, paper sized with cationic rosin undergoes minimal acid tendering thereby increasing whiteness and life.

3. Reduces Environmental Pollution - Cationic Rosin is used for sizing under neutral conditions (PH range of 4.5 to 6.5) thereby reducing the discharge of acidic sewage. It reduces the build-up of sulfate ions from Alum in the white water system, reducing the quantity of white water required to be bled off from the system.
