Title
(EN) TACKIFIED EMULSION PRESSURE-SENSITIVE ADHESIVE
(FR) ADHESIF EN EMULSION COLLANTE ADHERANT PAR PRESSION
Abstract
(EN)
An inherently tacky, pressure-sensitive adhesive having good convertibility and improved low temperature performance at coat weights lower than conventional systems is provided. The pressure-sensitive adhesive comprises (a) an emulsion polymer formed from a monomer mix comprising 35 to 60 % by weight alkylacrylates, 15 to 35 % by weight vinyl esters, 15 to 35 % by weight diesters of dicarboxylic acids, and up to about 5 % by weight unsaturated carboxylic acids, and (b) a tackifier comprising a hydrocarbon resin component and a rosin-based resin component, with an acid number of 30 to 45 and a softening point of 55 to 65 °C. A preferred pressure-sensitive adhesive comprises 8 to 12 parts by weight tackifier per 100 parts by weight pressure-sensitive adhesive polymer, with the preferred tackifier comprising an aromatic modified aliphatic resin containing wood rosin.
(FR)
Un adhésif adhérant par pression et collant en soi présentant une bonne convertibilité et une efficacité améliorée à basse température avec des poids de couche de recouvrement inférieurs à ceux des systèmes conventionnels. Ledit adhésif adhérant par pression comprend (a) un polymère en émulsion formé par un mélange de monomères contenant 35 à 60 % en poids d'acrylates d'alkyle, 15 à 35 % en poids d'esters de vinyle, 15 à 35 % en poids de diesters d'acides dicarboxyliques, et jusqu'à environ 5 % en poids d'acides carboxyliques insaturés, et (b) un agent donnant du collant comprenant un composant à résine d'hydrocarbure et un composant à résine de colophane, et présentant un indice d'acidité de 30 à 45 et un point de ramollissement de 55 à 65 °C. Un adhésif adhérant par pression préféré selon l'invention comprend 8 à 12 parties en poids d'agent donnant du collant pour 100 parties en poids de polymère adhésif adhérant par pression, l'agent donnant du collant préféré comprenant une résine aliphatique modifiée aromatique contenant de la colophane de bois.
