Title (EN) SURFACE TREATMENT COMPOSITION, ITS USE AND A METHOD FOR PRODUCING PAPER, BOARD OR THE LIKE
(FR) COMPOSITION DE TRAITEMENT DE SURFACE, SON UTILISATION ET PROCÉDÉ DE PRODUCTION DE PAPIER, DE CARTON, OU SIMILAIRE
Abstract:
(EN) The invention relates to a surface treatment composition comprising anionic polyacrylamide, which has a weight average molecular weight, MW, in the range of 100 000 – 2 000 000 g/mol, and free glyoxal. Further, the invention relates to the use of the surface treatment composition, a method for producing paper, board or the like and to a paper product.
(FR) L'invention concerne une composition de traitement de surface comprenant un polyacrylamide anionique, qui présente une masse moléculaire (MW) moyenne en poids comprise dans la plage de 100 000 à 2 000 000 g/mol, et du glyoxal libre. En outre, l'invention concerne l'utilisation de la composition de traitement de surface, un procédé de production de papier, de carton ou similaire, et un produit en papier.
