Universal Starch Chem Allied Limited

Dondaicha Warwade, Dhule, Maharashtra

It is a cationic derivative of starch manufactured by using high quality quaternary Ammonium compounds under controlled conditions of parameters to achieve the high degree of substitution.

Application :It improves the inner strength of paper through fibre to fibre bonding. It acts as an Adhesive in pigment coating. It has the suitable viscosity and reduce the pollution control of paper industry.

Description :

• UniCat S 25 is cationic wet end starch, used in the manufacturing of papers/boards to increase the internal strength properties as well as the retention of fillers and fines.
• UniCat S 25 has a cationic charge attached to it, which improves the internal strength properties of the paper. The electro kinetic attraction promotes a more intimate contact between the anionic cellulosic fibre surfaces and the starch hydroxyls

Physical Properties :

• Physical form- Powder
• Colour - White

Application : UniCat S 25 can be used to increase the retention of fillers and finers and to improve sheet strength properties at a low cost. It can be used at a level of 2-10 kg per ton of pulp. UniCat S 25 can be used for emulsification of AKD/ASA under high agitation. Typical solids of UniCat S 25 are in between 2-6% .

Advantages UniCat S 25 provides the paper maker :-

• Increased internal strength properties & retention of fillers & finers.
•  Faster drainage & improved sheet formation.
• Improved effluent quality & reduced costs.

Preparation :

For preparing paste, UniCat S 25 is slurried in cold water till free of lumps at 3-6% solids.The slurry is heated to 95°C and maintained at that temperature with mild agitation for 30 minutes. After cooking, the paste is diluted to 1% solids before adding to stock or may be added directly to the stock. The point of addition is commonly at the intake side of the fan pump or as close as possible to the head box of the paper machine.
