Ply-Bonding Agents HICON Series

HICON Series - Ply-Bonding Agents HICON series is a mixture of the epoxidized polyaminoamide and a specialized polyamine that can be used as ply-bonding agent for paperboard over a wide range of pH. It provides superior bonding strength to the multi-layered paperboard, especially under high atmospheric moisture. Paper is a layered mat consisting of a network of cellulose fibers bonded together. Each of the fiber-fiber contacts is held together by intermolecular hydrogen bonding and/or Van der Waals forces which are very sensitive to water, the extent of bonding decreasing steadily as the moisture (water) content of the paper increases. In the case of multi-layered paperboard exposed to highly moisturized atmosphere, the strength drop is usually greater than the case of paper.To produce papers and paperboards that retain some of their original dry strength when wet, it is necessary to do one of follows: Add to or strengthen existing bonds Protect existing bonds Form bonds that are insensitive to water Produce a network of material that physically entangles with the fibers. To achieve these, HICON series have been developed which are chemically reactive and water-soluble polymers. The chemical reactivity of HICON series can be of either the polymers can react with themselves (homo-crosslinking) or they can react with cellulose or the materials at the cellulose interfaces (co-crosslinking). HICON series can also be applied to the surface of papers and paperboards by spraying as well as the internal addition method. It might be a good idea for spraying HICON solution to the surface of paper web when the content of anionic trash in the papermaking system is high. It is very easy to handle of HICON series due to its low viscosity. Mill experience data of HICON series obtained from a typical paperboard mill will be supplied on request. 1.

Heath and Safety Toxicity, caused by HICON products alone and when incorporated into papers and paperboards, has not been reported so far. The content of HICON series is listed under Title 21 of the Code of Federal Regulations, Paragraph 176.170. However, contact with the HICON solution should be avoided because of its acidic nature. When exposed to the solutions, wash with fresh water immediately. These data are given for information only.
