Abstract
Priming of elastomers with polycarboxylic acid solutions, in order to facilitate the bonding thereof by means of contact adhesives, generally based on single-component polyurethanes, consisting in rubbing the previously sandpapered surface of the elastomer with solutions of a polycarboxylic acid. The acid facilitates the elimination of zinc stearate and gives rise to the creation of C=O groups on the surface of the elastomer. This treatment can be an alternative to chlorination, the usual procedure for facilitating the bonding between elastomers and polyurethane adhesives. The advantages thereof, relative to chlorination, lie in a significant reduction in the duration of the treatment, in elimination of the toxicity due to the chlorinating agents and in the good stability of the treating solutions. It has its application in the footwear industry, and also in other related industries.
