An assembly includes a substrate, a trim member and a heat-activated adhesive member. The substrate defines at least two surfaces including a finished surface and an unfinished surface. The trim member defines at least two surfaces including an outwardly-facing finished surface and an inwardly-facing attachment surface. The inwardly-facing attachment surface of the trim member is arranged over and trims the unfinished surface of the substrate. The finished surface of the substrate and the outwardly-facing surface of the trim member form a cooperating finished surface of the assembly. The heat-activated adhesive member is disposed over both of the unfinished surface and the inwardly-facing attachment surface of the trim member to indirectly attach the unfinished surface of the substrate to the inwardly-facing attachment surface of the trim member. A method is also disclosed.

A sealing film suitable for food packaging is disclosed, which adopts the following solution. The sealing film comprises, in sequence, a PET layer, a VMPET layer and a PE layer from outside to inside, wherein the PE layer comprises 100-110 parts of PE, 15-20 parts of EVA, 15-20 parts of EAA, 55-60 parts of HDPE and 10-15 parts of LLDPE in parts by mass. In this manner, the addition of HDPE and LLDPE into the PE layer is intended to enhance the tensile strength of the sealing film.

In a method for coating a sliding element, in particular a piston ring or a cylinder liner of an internal combustion engine, DLC phases are embedded into a hard material layer as said hard material layer is deposited. A sliding element, such as a piston ring or a cylinder liner of an internal combustion engine, comprises a hard material layer with embedded DLC phases.

There is prepared a polyester sheet having a surface layer in which 0.05 to 2.0% by weight of an ester compound, which is synthesized by using a polyvalent organic acid having three or more carboxyl groups and an aliphatic monohydric alcohol having eight or more carbon atoms, and 0.01 to 0.5% by weight of inert inorganic particles having an average particle diameter of 2 to 15 μm, are blended into a polyethylene terephthalate-based polymer. Accordingly, the polyester sheet has a rational balance between sliding properties and transparency.

The invention comprises a relatively lightweight cementitious-based material panel. The cementitious-based material panel comprises a foam insulating panel having a first surface and a second surface; a first structural layer of cementitious-based material formed on the first surface of the foam insulating panel and affixed thereto; and a second non-structural layer of cementitious-based material formed on the second surface of the foam insulating panel and affixed thereto. The second non-structural layer of cementitious-based material is substantially thinner than the first structural layer of concrete. The second non-structural layer of cementitious-based material is preferably formed from polymer modified concrete, plaster or mortar. A method of making the cementitious-based material panel is also disclosed.

A coated substrate. The coated substrate includes a unitary substrate having a major surface. A first coating is applied to a first surface segment of the major surface. A second coating applied to a second surface segment of the major surface. The first coating is different than the second coating.

A flat steel product for hot forming may be produced from a steel substrate that includes a steel comprising 0.1-3% by weight Mn and up to 0.01% by weight B, along with a protective coating that is applied to the steel substrate. The protective coating may be based on Al and may contain up to 20% by weight of other alloy elements. Also disclosed are methods for producing such flat steel products, steel components, and methods for producing steel components. Absorption of hydrogen is minimized during heating necessary for hot forming. This is achieved at least in part through an alloy constituent of 0.1-0.5% by weight of at least one alkaline earth or transition metal in the protective coating, wherein an oxide of the alkaline earth or transition metal is formed on an outer surface of the protective coating during hot forming of the flat steel product.
