Disclosed is a liquid urethane containing adduct; a process for the preparation thereof; and applications therewith. More specifically this invention relates to a stable adduct which is a liquid at room temperature and which contains a plurality of urethane linkages, and yet which is substantially free of any isocyanate functionality or isocyanate-reactive functionality. Such adducts can be used as quenchants, lubricants, or surfactants.
L'invention porte sur un produit d'addition contenant de l'uréthane liquide, sur son procédé de production et des applications correspondantes. Cette invention traite plus précisément d'un produit d'addition stable, liquide à la température ambiante, contenant des liaisons uréthane et quasiment exempt, de surcroît, de toute valence fonctionnelle isocyanate ou de toute valence fonctionnelle réagissant avec l'isocyanate. On peut utiliser ces produits d'addition comme liquides de trempe, lubrifiants ou agents tensioactifs.
