Title
(EN) BINDER COMPOSITION FOR MOLD PRODUCTION AND PROCESS FOR PRODUCING MOLD
(FR) COMPOSITION DE LIAISON POUR LA PRODUCTION DE MOULES ET PROCEDE DE PRODUCTION DE MOULES
Abstract
(EN)
A binder composition for use in producing molds, which contains a binder obtained by the polycondensation of monomers mainly comprising furfuryl alcohol, urea and an aldehyde and wherein a difference (A-B) between the weight percentage (A) of the feed furfuryl alcohol and the weight percentage (B) of the unreacted furfuryl alcohol, both based on the binder, ranges from 5.0 to 60.0. The composition serves to accelerate the hardening of the binder without worsening the working environment.
(FR)
Composition de liaison destinée à être utilisée pour la production de moules. Le liant est obtenu par polycondensation de monomères renfermant essentiellement de l'alcool furfurylique, de l'urée et un aldéhyde. La différence (A-B) entre le pourcentage en poids (A) de la charge d'alcool furfurylique et le pourcentage en poids (B) de l'alcool furfurylique n'ayant pas réagi, considérés l'un et l'autre sur la base du liant, se situe entre 5,0 et 60,0. La composition sert à accélérer le durcissement du liant sans affecter le milieu de travail.
