Title (EN) POLYMERIC MICROSPHERES FOR LOW-FRICTION SURFACES
(FR) MICROSPHERES POLYMERES IMPRIMANT UN FAIBLE COEFFICIENT DE FRICTION SUR DES SURFACES
Abstract:
(EN) The present invention relates to polymeric microspheres comprised of short-chain diol diacrylate homopolymers or copolymers of diol diacrylates and long-chain acrylate esters, which exhibit excellent antifriction characteristics when applied on the surface of plastic sheets. Treated sheets exhibit a significantly lower coefficient of friction than sheets treated with commercially-available microspheres.
(FR) La présente invention se rapporte à des microsphères polymères composées d'homopolymères de diol diacrylates à chaîne courte ou de copolymères de diol diacrylates et d'esters d'acrylate à longue chaîne, qui présentent d'excellentes caractéristiques d'antifriction lorsqu'elle sont appliquées sur la surface de feuilles en plastique. Les feuilles traitées présentent un coefficient de friction bien plus faible que les feuilles traitées avec les microsphères disponibles dans le commerce.
