Abstract: The present invention relates to panels or slabs formed by stone agglomerate for the manufacture of which an organic binder containing an ingredient of a plant origin is used. The panels or slabs object of the invention are formed from stone materials or the like, granulated and subsequently agglomerated by means of a binder, specifically an organic resin containing one or more polyols of a plant origin. Furthermore, by means of using this binder together with materials from waste and used and/or recycled products, a material with good features and with a very high content of recycled material or material of a renewable origin can be obtained. The manufactured panel or slab containing a resin part of a plant origin of the present invention is particularly suitable for its use indoors as a kitchen counter, a bathroom counter, or any work surface, as well as for its use as flooring or sidings.

Abstract: The invention relates to a method for manufacturing non-flat agglomerated stone products, such as sinks, washbowls, etc., by means of vacuum vibrocompression. A mold into which a molding mass is discharged is used in the method. The method allows obtaining products with two or more differentiated colors.

Abstract: Article in the form of a slab or flag fabricated from stone agglomerate coated with thin, transparent films of TiO2 or ZnO, using dry deposition techniques, with a high level of resistance to solar degradation. The article has the form of a slab or flag fabricated from stone agglomerate coated with a thin, transparent film of TiO2 and/or ZnO with low or zero photocatalytic activity, the film being deposited by dry deposition, physical vapour deposition (PVD) or plasma enhanced chemical vapour deposition (PECVD) techniques. The article has a high level of resistance to solar degradation, which means that the resulting material is suitable for external environments.

Abstract: The invention relates to a method for producing an article from agglomerated stone, for example a slab for construction or decoration, comprising the following steps: bringing into contact (i) an inorganic filler, (ii) a polyester resin precursor composition and (iii) a powdered electrically conductive component; mixing same to produce a uniform mass; distributing part of the mass on a substrate; pressing the distributed mass in a vibro-compaction press under vacuum conditions; and hardening the mass by means of polymerisation of the polyester resin.
