Abstract
The present invention is related to decorative surface coverings, in particular floor or wall coverings, exhibiting low volatile organic compounds (VOC) emission, comprising one or more adjacent plasticized polyvinyl chloride layers and a polyurethane top-layer, said top-layer being obtained from radiation curing a 100% solids polyurethane formulation.
Claims17
Decorative surface covering exhibiting low volatile organic compound (VOC) emission, said surface covering comprising one or more adjacent plasticized polyvinyl chloride layers and a polyurethane top-layer comprising acid functionalities, the polyurethane top-layer being obtained from a 100% solids radiation curable polyurethane composition, wherein the decorative surface covering has a total volatile organic compound (TVOC) emission lower than 100 μg·m−3, measured after 28 days in accordance with ISO 16000-6, ISO 16000-9 or ISO 16000-10.
Decorative surface covering exhibiting low volatile organic compound (VOC) emission, comprising a mechanical embossed textured and/or patterned structure, said surface covering further comprising one or more adjacent plasticized polyvinyl chloride layers and a polyurethane top-layer comprising acid functionalities, the polyurethane top-layer being obtained from a 100% solids radiation curable polyurethane composition, wherein the polyurethane top-layer prevents plasticizer migration and exudation and wherein the decorative surface covering has a total volatile organic compound (TVOC) emission lower than 100 μg·m−3, measured after 28 days in accordance with ISO 16000-6, ISO 16000-9 or ISO 16000-10.
