Cationic Starch

• Catonil provides the paper maker:
• Increased internal strength properties and retention of fillers and fines.
• Faster drainage and improved sheet formation.
• Improved effluent quality and reduced costs.

Description:
Catonil 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.
CATONIL is available in three grades as mentioned below:
CATONIL-200,  DS  0.015 min.
CATONIL-300,  DS  0.025 min.
CATONIL-400, DS  0.040 min.

Typical Analysis
Colour, Form: White powder
Moisture: Not more than 14%
Ash on ds: Not more than 1.5%   
pH of 5% solution: 4.5-6.5
Screen analysis: 100% passing through 85 mesh BS

Application: Catonil can be used to increase the retention of fillers and fines and to improve sheet strength properties at a low cost. It can be  used at a level  of 2-10kg per ton of pulp.

Preparation: For preparing paste, Catonil is slurried in cold water till free of lumps at 3-6% solids. The slurry is heated to 95C 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.

Packing: Catonil is available in 25 kg plastic lined HDPE woven bags.
