Latest Patents

Duong's latest patents include a highly-filled chlorine-free surface covering and a multiple step UV curing process. The highly-filled chlorine-free surface covering is designed to be a floor covering, featuring a resin layer that contains about 80% to about 95% by weight of filler and a chlorine-free binder. This binder is a mixture of maleic anhydride grafted polyethylene and a substantially linear ethylene/octene copolymer, with a specific weight ratio. The preferred formulation also includes a solid tackifier selected from a group of hydrocarbon resins.

The multiple step UV curing process involves a three-stage method where a UV-curable substrate is initially exposed to long wavelength light of low intensity. This process allows the bottom portion of the substrate to gel while leaving the top surface unaffected. The subsequent stages involve shorter-wave length UV light and conventional exposure to strong UV light, resulting in a finely controlled surface texture. These innovations are particularly useful for floor and wall coverings.
