Patent

CA 2625465

The present invention relates to a composite article obtained from binding or adhesion of particulate matter with a polyurethane binder which is derived from a urethane-modified isocyanate obtained by reaction of an isocyanate with a polyether polyol based on an initiator containing a tertiary nitrogen atom. Such composite articles can be, for example, recreational matting or tiles, sports or running tracks, or flooring, or laminates.

La présente invention se rapporte à un article composite obtenu par la liaison ou l'adhésion d'une matière particulaire avec un liant polyuréthane qui est dérivé d'un isocyanate à modification uréthane, lequel est obtenu par la mise en réaction d'un isocyanate avec un polyol de polyéther à base d'un initiateur contenant un atome d'azote tertiaire. De tels articles composites peuvent par exemple se présenter sous la forme de dalles ou de tapis récréatifs, de pistes de sport ou de course à pied, de planchers ou de stratifiés.
