Fixing Agent 

Additives are commonly used in paper industry to improve product properties and process efficiency. For good performance, most of the wet end additives must have good adsorption properties to pulp fibers. Therefore, the topic of additive adsorption to cellulosic fibers has attracted considerable attention over the years

Fixing agents are used to improve retention of internal sizing agents and to enhance sizing degree.
They also reduce machine deposits caused by internal sizing agent.

fixing agent is polyelectrolyte, consists of a series of organic synthesis with low molecular weight and strong cationic, which is generally 100% cationic. Product character is aqueous solution

Characteristics

• Improve the retention of AKD / ASA / Rosin sizing agents that allow the lower dosage of using sizing agents.
• Increase the rate and the degree of AKD sizing in shorter time
