PROCEDE DE PREPARATION DE COMPOSITIONS ORGANOPOLYSILOXANIQUES CONTENANT DES POLYACYLOXYSILANES ET DURCISSANT TRES RAPIDEMENT A LA CHALEUR EN ELASTOMERES EN PRESENCE D'ACCELERATEUR A GROUPEMENT CARBOXY-2 CARBOXAMIDE

摘要

Organopolysiloxane compositions comprising a polyhydroxylated polysiloxane and a polyacyloxysilane, whether in single- or two-component form, rapidly cure into elastomeric state (and are thus useful, e.g., as sealing materials) in the presence of a 2-carboxycarboxamide cure autoaccelerator.
