Description
[Solenis, formerly Hercules Inc] A polyamidoamine-epichlorohydrin (PAE) resin, a high efficiency, cationic resin that functions under acid or alkaline papermaking conditions. Kymene is used to add wet strength to paper with out changing its pH. Hercules filed its first patent for PAE resin in 1957 and then introduced it to the market as KymeneTM 557 wet-strength resin. Although Kymene 557H is used primarily to impart wet strength, it has several other important applications in papermaking such as retention, drainage, and flotation aid. However, since some byproducts of the PAE process were determined to be carcinogenic, a series of second generation PAE technologies — Kymene SLX — were launched in 1990. Later high filtration membrane separation technology made it possible to manufacture higher-solids, higher-efficiency wet-strength resins with very low concentrations of reaction by-products.
2010 The G1 portfolio gets updated to have much lower 1,3-DCP and 3-MCPD.
