The present disclosure is directed to a two-component bonding agent composition and a process for applying a layer of the bonding agent composition to substrate layers to make laminates.

A rectangular panel for floor-, wall- or ceiling coverings is provided comprising a visible decorative side, wherein the decorative side comprises at least one undulated edge line, which extends along the long side edges of the panel, said undulated edge line having a different design than the rest of the decorative side. In the provided panel(s), the physical edges and the optical edges may diverge, which provides the possibility that multiple panels can be installed as floor ceiling or wall covering in a way that the physical edges in a corresponding covering become almost invisible whereas the optical edges (i.e. the undulated edge lines) are perceived as artificial optical edge of virtual panels forming the covering.

The present invention relates to an ethylene polymer composition for use in adhesive applications, to an article comprising the ethylene polymer composition and to a process for producing said article.

An object of the present invention is to provide a laminate having a good appearance, such as surface smoothness (thickness uniformity); high surface hardness; recoatability that enables the functional layer to be provided on the hard coat layer; and a function, such as scratch resistance and stain repellency. The present invention relates to a laminate including a laminated portion constituted of two or more layers including a hard coat layer and a functional layer in contact with the hard coat layer, and a substrate in contact with the hard coat layer, the functional layer being the outermost surface of the laminate: wherein the hard coat layer is a cured product layer of a curable composition containing a polyorganosilsesquioxane and silica particles, the silica particles including a group containing a (meth)acryloyl group on the surface.

A flooring assembly comprising a flooring unit comprising a stability core layer having a plurality of edge surfaces, two of which have an interlocking mechanism for attachment to the edge surfaces of the stability core of adjacent flooring units, and a sound attenuating acoustic layer attached to the bottom surface of the stability core layer.

A wear-resistant composition which includes a polymeric hot-melt binder system which includes at least one wear-resistant additive which includes diamond particles dispersed therein. A surface covering includes a base layer, a wear-resistant layer, and optionally a topcoat layer. The wear-resistant layer is laminated to the base layer. The wear-resistant layer may be formed by dispersing a plurality of wear-resistant additive particles, which include diamonds, into a liquid to form a stable liquid dispersion, blending the stable liquid dispersion into a polymeric resin to form a mixture, and extruding the mixture to form the wear layer.

Disclosed herein is a sound absorbing structure which includes at least one sound-permeable nanofiber layer and at least one sound absorbing layer; in which, the sound-permeable nanofiber layer is placed alongside of the sound absorbing layer.

A sound insulating material, a sound insulating plate, and a partition structure of a train carriage are provided. The sound insulating material comprises the following components in weight ratio: 2-8 parts of tricalcium silicate; 4-10 parts of calcium hydroxide; 10-30 parts of aluminosilicate; 4-10 parts of alumina; 5-15 parts of iron oxide; 10-30 parts of a binder; and 5-10 parts of a curing agent, wherein the binder is at least two of lithium silicate, sodium silicate and calcium silicate; the curing agent is at least one of lithium oxide, magnesium oxide and silica; and the mixture of the aluminosilicate, alumina and iron oxide expands at 1000 C.-1350 C. to form particles. The sound insulating plate made of this material is lightweight and has a sound insulation capacity of 35-42 dB.

The present disclosure is directed to a two-component bonding agent composition and a process for applying a layer of the bonding agent composition to substrate layers to make laminates.

A panel suitable for constructing a floor or wall covering includes a core comprising a mineral composite comprising a mineral and a filler. The panel further comprises an additive within the core in order to improve the flexibility and/or tensile strength of the panel.
