EVERTERIC – MODIFIED STARCH
EVERTERIC – Amphoteric Starch is a modified starch that contains both positive and negative ion (Anioinic& Cationic) groups. It is used as wet-end additives, surface sizing agent and coating agent in the paper making. The product is equally effective in acid, neutral or alkaline papermaking.
The main use of EVERTERIC – amphoteric starch is enhancement of dry strength, improving drainage and retention.
In the paper making process several materials are anionic such as wood fibers, titanium dioxide, clay, expanders, pigment dispersant, black liquor, bleach chemicals etc, whereas some materials are cationic such as alum, poly aluminium chloride (PAC), cationic resin, some retention aids etc. So it is very significant to maintain a clean and ionically balance environment to attain efficient result, which is done by amphoteric starch.
