Latest Patents

Among his latest innovations, Sigman has developed a revolutionary aminoplast/polyurethane wear layer for PVC support surfaces, which boasts a resilient surface covering. This wear layer includes a crosslinked aminoplast/polyurethane that adheres directly to a vinyl support surface. The innovative composition allows for improved adhesion by integrating at least 20% polyurethane by weight based on the total amount of aminoplast, polyurethane, and epoxy resin. Alternatively, the wear layer can be applied to a gelled, unfused vinyl support surface, facilitating a single-step fusion and curing process.

Additionally, Sigman has also created an effective seam cleaning composition, available as a paste, cream, or liquid. This formulation comprises a hydrocarbon solvent and a finely divided inorganic powder. It is specifically designed for treating seams of various floor coverings, particularly those that are highly stain and soil resistant. The seam cleaning composition significantly enhances the adhesion of subsequent seam coaters without altering the floor's appearance or resistance to staining or soiling, while also preventing bubble formation within applied seam coaters.
