Patent

CA 2503866

A polyurethane system is disclosed for achieving a polyurethane surface derived from the catalyzed reaction of equivalent volumes of a polyisocyanate component and an active hydrogen component. The two-component system achieves optimal gel time and cure response for application as an athletic surface having an isocyanate index between about 105 and 115. Moreover, the disclosed invention achieves these results with a 1:1 by volume two-component system, which minimizes mixing errors during application of the surface.

L'invention concerne un système polyuréthanne qui permet de produire une surface polyuréthanne dérivée de la réaction catalysée de volumes équivalents d'un composant de polyisocyanate et d'un composant d'hydrogène actif. Ce système à double composant permet d'obtenir un temps de gélification et une réponse de durcissement optimaux pour une application en tant que surface d'athlétisme présentant un indice d'isocyanate compris entre environ 105 et 115. De plus, l'invention permet d'atteindre ces résultats à l'aide d'un système à double composant à 1:1 par volume, ce qui réduit les risques d'erreur de mélange pendant l'application de la surface.
