  • Patent number: 7462400
    Abstract: Disclosed herein are a caster-resistant surface laminate using a synthetic resin and a flooring comprising the surface laminate. The surface laminate utilizes buffering properties of a synthetic resin layer, thus minimizing damage to the surface of the flooring. The surface laminate uses a resin selected from PVC, PE, PET, PETG, PCTG and PU in order to enhance the caster resistance, impact resistance and water resistance. As a result, the surface laminate has improved physical properties without occurrence of damage, such as hollowing and breakage, caused by external impacts, as compared to conventional surface laminates. In addition, the caster-resistant surface laminate attains interior decorative effects by coloration of the synthetic resin layer.

  • Patent number: 7449231
    Abstract: Disclosed herein is a UV surface-coated laminate wood flooring for an under-floor heating system comprising a back-grooved base, an adhesive layer and a printed wood veneer layer wherein the printed wood veneer layer is produced by impregnating and coating a low-basis weight printed paper with a thermoplastic or thermosetting resin, integrally forming the paper layer with a low-price reinforcing layer by pressing under high pressure, treating the surface of the paper layer with an acryl based primer, and coating the primer-treated paper layer with a solvent-free type UV coating paint, and wherein the back-grooved base and the printed wood veneer layer are adhered to each other by the adhesive layer.

  • Publication number: 20030024637
    Abstract: Abrasion resistant laminates which are aesthetically pleasing, water-resistant/water-repellant, and flexible are formed by laminating a wear-resistant durable multi-layer top assembly to a base layer formed from an inexpensive, water resistant, polymeric substrate. The durable multi-layer wear-resistant top layer assembly comprises a wear resistant upper layer, a decorative layer, and a core layer. The polymeric base layer comprises a water resistant substrate which is positioned beneath the top layer assembly and is laminated thereto with a water resistant adhesive. This abrasion resistant laminate could be applicable in a variety of situations wherever a decorative and/or abrasion resistant product could be used and would be particularly useful in the floor covering industry.
