    Abstract: A ceramic-based hardwood floor finishing method resistant to panelization, exhibiting improved durability, and suitable for on-site use. The method is comprised of laying down successive layers of water-based primer, armor coat and top coat. The water-based primer utilizes a low resin content and a low co-solvent concentration to substantially reduce panelization of hardwood boards. The water-based armor coat is comprised of large particulate size ceramic additives which, in combination with a low resin content, allow the formation of a microscopic bead structure on the surface of the finish which provides enhanced durability.

    Abstract: A process for manufacturing nonwoven materials such as floor or wall coverings from natural or synthetic oils and natural or synthetic elastomers is carried out in two reaction phases. In the first reaction phase, a mixture of a stand oil or an equivalent synthetic polymer oil is homogenized with fillers and partially polymerized and partially crosslinked at high temperature to form an intermediate product I. The ground intermediate product I is then homogenized with a natural or synthetic elastomer, in particular natural rubber, fillers and a peroxide and crosslinked and polymerized at a high temperature. The process is suitable for manufacturing homogeneous and possibly marbled floor coverings based on natural materials and processing outstanding physical and optical properties.
