Fixing agents are used to improve retention of internal sizing agents and to enhance sizing degree. They also reduce machine deposits caused from internal sizing agent.
They improve the retention of AKD / ASA rosin sizing agents. This may allow lower dosage of size to be used.
AKD size develops sizing too slowly in some uses and these resins can increase the rate and the degree of AKD sizing.Fixing Aid – Product Characteristics
