Binders for paints and varnishes — Determination of hydroxyl value — Part 2: Titrimetric method using a catalyst
ISO 4629-2:2016 specifies a titrimetric method for determining the hydroxyl value of resins, binders for paints and varnishes, primary alcohols, glycols and fats. Whether it can be applied for hydro carboxylic acids, phenolic hydroxyl groups, polyols such as trimethyl propane and substances containing aromatic groups have been activated for Friedel-Crafts acylation shall be decided on case-to-case basis. Under the right conditions, the method is also applicable for determining the hydroxyl value of castor oil and its derivatives.
Liants pour peintures et vernis — Détermination de l'indice d'hydroxyle — Partie 2: Méthode titrimétrique utilisant un catalyseur
ISO 4629-2:2016 spécifie une méthode titrimétrique permettant de déterminer l'indice d'hydroxyle des résines, des liants pour peintures et vernis, des alcools primaires, des glycols et des matières grasses. Son applicabilité pour les acides hydrocarboxyliques, les groupes hydroxyle phénoliques, les polyols tels que le triméthylpropane et les substances contenant des groupes aromatiques activés pour une acylation de Friedel-Crafts, doit être déterminée au cas par cas. Dans les conditions appropriées, la méthode est également applicable pour déterminer l'indice d'hydroxyle de l'huile de ricin et de ses dérivés.
