摘要:
A multi-component composition contains a) a polyol component having a1) acrylate polyol and a2) at least one of polyester polyol and polyether polyol, wherein the equivalent ratio of hydroxyl groups of acrylate polyol to hydroxyl groups of the at least one of polyester polyol and polyether polyol is in the range of 0.4 to 3.8, and b) an isocyanate component containing b1) aliphatic polyisocyanate monomer, dimer and/or trimer, and b2) aliphatic polyisocyanate prepolymer, wherein the equivalent ratio of isocyanate groups of aliphatic polyisocyanate monomer, dimer and/or trimer to isocyanate groups of aliphatic polyisocyanate prepolymer is in the range of 0.5 to 2.6. The multi-component composition is suitable for use as a top coat on elastic membranes, in particular roofing membranes, to provide sufficient weathering resistance/protection.

Described herein are surface coverings comprising: a linoleum core; a first major surface terminating at a first edge, a second major surface terminating at a second edge, and a peripheral edge surface extending between the first and second edges; wherein the peripheral edge surface is planar and oriented obliquely to the first major surface and the second major surface. Methods of making and using these surface coverings are also described.

A building board is finished in a first processing station via laterally operating processing means, where-in a first edge strip is glued along a first edge side of body element of the building board. In a second processing station a primary surface layer is glued, by vertically operating processing means, to cover the entire primary main side and the primary side of the first edge stripe. Thereafter, a vertical pressure is applied over the body element and the first edge stripe across a working direction while the body element and the first edge stripe pass the second processing station in such a manner that a primary side of the first edge stripe is brought in level with a primary main side of the body element when passing the second processing station.
摘要:
A laminated floor tile includes the following layers laminated together into a single unit, a base having an underside, an upper surface, and perimetric edges, the base being formed of a high impact copolymer material designed to provide a slight flexure, the base including tabs designed to interact with adjacent floor tiles to hold the adjacent tiles fixedly in place, and panels extending upwardly from the perimetric edges of the base and forming the upper surface into a tray shape, graphic media positioned on the base within the tray, and a clear protective layer overlying the graphic image.

A flooring product comprises a heterogeneous design layer having multiple regions wherein two regions comprise compositions having different recycle content or renewable content. The thickness of the design layer may be greater than the dimensions of the regions or the regions may extending from the top surface of the layer to the bottom surface of the design layer. The heterogeneous layer may be composed of consolidated particles/chips which may contain a polyester binder system with a renewable component. Additionally, a method for making a heterogeneous layer having a target wt % recycle content or renewable content is also disclosed.

Pattern match indicators are embedded in the pattern design in the selvage edge portion of adjacent flooring sheets. The pattern match indicators are spaced apart with the distance between the adjacent pattern match indicators equal to the repeat length of the pattern design. In one embodiment the pattern mark indicators may appear as small bars approximately ¼″ wide and approximately ½″ to approximately ⅝″ in length. Prior to cutting off the selvage edge portions, the adjacent flooring sheets are laid with the edge portion of one flooring sheet overlapping the other flooring sheet. The pattern match indictors are located with the pattern match indicators collinear with respect to the across-machine direction and with a gap of predetermined dimension between them. With the flooring sheets overlapped, the selvage edge portions are simultaneously cut parallel to the longitudinal edges of the flooring sheets and within the gap between the pattern match indicators,
摘要:
A laminated fabric floor product having an encapsulated fabric scrim within a vinyl resilient flooring structure. The laminated fabric floor product structure includes a PVC calendered base, a first hot melt film, a fabric, a second hot melt film, a calendered clear film, and a high performance coating. Traditional foamed and non-foamed substrates used in the flooring industry can be used in addition to the calendered base. All types of fabrics and scrims can be encapsulated. The fabrics can be both woven and non-woven types. Open scrims can be used with base layers that are printed or have a visual pattern so that design features and colors can be seen through the open areas of the scrim. The fabric layer can be printed with a design pattern and adhered to the base layer or substrate by the first hot melt adhesive film layer. The clear layer is adhered to the fabric layer by the second hot melt adhesive layer.
摘要:
A preglued underlayment assembly comprising a substantially rigid underlayment having an upper and a lower surface, a pressure sensitive adhesive layer disposed on the upper surface, and a release layer disposed on the adhesive layer. A second pressure sensitive adhesive layer and another release layer are optionally provided on the lower surface of the preglued underlayment. One or more performance enhancing layers, such as foam and solid layers, can be disposed between the underlayment and the adhesive layer to modify and/or enhance various properties of the preglued underlayment. Mechanical fasteners, such as staples, penetrate the preglued underlayment assembly and engage a structural support member to attach the preglued underlayment assembly thereto. A method of installing a surface covering over a structural support member utilizing the preglued underlayment assembly is also disclosed.
