摘要: Composition d'urethane dilatable utilisee comme mastic et caracterisee en ce qu'elle comprend un premier composant contenant melange d'un elastomere reactif liquide hydroxy fonctionnel de sels metalliques sulfonates organiques, ainsi qu'un deuxieme du polyisocyanate. expandable urethane composition used as a filler and characterized in that it comprises first component containing mixture of hydroxy-functional liquid reactive elastomer metal salts organic sulfonates, second La peut aussi contenir des pigments et/ou charges. The may also contain / or fillers. Le mousse presente d'excellentes proprietes flexibilite, resistance l'abrasion aux chocs, d'isolation phonique, adhere avantageusement surfaces graisseuses. foam sealant has excellent properties flexibility, to abrasion impact resistance, sound insulation, advantageously adheres greasy surfaces.
