Title
(EN) COATED INFILL AND ARTIFICIAL TURF WITH THE COATED INFILL
(FR) ÉLÉMENT DE REMPLISSAGE REVÊTU ET GAZON ARTIFICIEL AVEC L'ÉLÉMENT DE REMPLISSAGE REVÊTU
Abstract
(EN)
The present disclosure provides for a coated infill, an artificial turf that includes the coated infill and a method of making the coated infill of the present disclosure. The coated infill includes an infill granule, an exterior coating layer at least partially covering the infill granule, where the exterior coating layer includes a cured hydrophilic polyurethane, and an intermediate coating layer at least partially covering the infill granule, the intermediate coating layer comprising a cured polyurethane, where the cured polyurethane is different than the cured hydrophilic polyurethane and where the intermediate coating layer is positioned between the exterior coating layer and the infill granule, the exterior coating layer being an outermost layer of the coated infill.
(FR)
La présente invention concerne un élément de remplissage revêtu, un gazon artificiel qui comprend l'élément de remplissage revêtu et un procédé de fabrication de l'élément de remplissage revêtu selon la présente invention. L'élément de remplissage revêtu comprend un granulé de remplissage, une couche de revêtement extérieur recouvrant au moins partiellement le granulé de remplissage, la couche de revêtement extérieur comprenant un polyuréthane hydrophile durci et une couche de revêtement intermédiaire recouvrant au moins partiellement le granulé de remplissage, la couche de revêtement intermédiaire comprenant un polyuréthane durci, le polyuréthane durci étant différent du polyuréthane hydrophile durci et la couche de revêtement intermédiaire étant positionnée entre la couche de revêtement extérieur et le granulé de remplissage, la couche de revêtement extérieur étant une couche située le plus à l'extérieur de l'élément de remplissage revêtu.
