Abstract

L'invention concerne un procédé de fabrication d'un produit comprenant au moins deux parties, qui consiste à enduire au moins partiellement une des parties avec une résine dans laquelle est réparti un catalyseur piégé, à mettre en place les deux parties entre lesquelles on intercale la résine, et à libérer le catalyseur à l'intérieur de la résine pour amorcer la polymérisation au moment voulu. Ce catalyseur peut être piégé soit par encapsulation, soit par absorption/adsorption, à l'intérieur de la structure d'un substrat approprié, tel que la coque d'amande. Le catalyseur peut être un peroxyde organique, de l'acide formique ou de l'acide toluène-sulfonique. Un accélérateur peut être utilisé pour accélérer la polymérisation.
