Described herein is a weft-knitted spacer fabric and a preparation method thereof, a polyurethane foam composite material including the fabric, a preparation method of the composite material and its use in shoe materials. The weft-knitted spacer fabric consists of an upper surface layer, intermediate spacer yarns, and a lower surface layer, and the upper surface and the lower surface layer are connected by the tuck of the spacer yarns in the upper surface and the lower surface layer to form a three-dimensional structure in an integrated manner. The different selected tuck needle changes the connecting distance and the number of connections of the tuck, and the thickness of the spacer fabric and the arrangement density of the spacer yarns are changed by the action of the upper and lower surface layers of elastic yarns.

An object of the present invention is to provide a laminated polyester film that has good adhesion to an UV-curable resin, particularly has excellent adhesion to a coating agent such as an UV-curable ink, and has an excellent property to keep the adhesion at a high level over a long period of time. A laminated polyester film comprising: a polyester film; and a coating layer on at least one surface of the polyester film, the coating layer comprising a composition containing a polyurethane resin having a carboxyl group and having an acid value of 30 to 50 mgKOH/g and a crosslinking agent having a carboxyl group and having an acid value of 30 to 50 mgKOH/g.

A golf ball 2 includes a main body 4 and a paint layer 6 positioned outside the main body 4. The main body 4 includes a spherical core 8, a mid layer 10 positioned outside the core 8, and a cover 12 positioned outside the mid layer 10. An indentation depth, measured when the paint layer 6 in a cross-section along a plane passing through a central point of the golf ball 2 is pressed by a force of 30 mgf in a direction perpendicular to the cross-section, is not less than 300 nm and not greater than 3000 nm. The paint layer 6 preferably has a thickness of not less than 5 m and not greater than 50 m.

A class of alkanol amine ligands reacted with bismuth carboxylates lends unique curability properties to isocyanate and polyols for production of polyurethane for CASE applications, including growing demand for polyurethane spray-foam. The amino-alcohol ligand, when associated with bismuth neodecanoate, offers improved moisture and solvent resistance during B-side (polyol) storage, cure rates analogous to tin-based curatives, and overall good final physical properties of the cured polyurethane.

The present disclosure provides a process. The process includes (A) providing at least 6 film layers, each film layer being a pearlized biaxially oriented polypropylene; (B) applying a solvent-less adhesive at a coat weight of 2.0 g/m.sup.2 to 3.5 g/m.sup.2 between each film layer; and (C) forming a laminate, the laminate having a thickness of at least 300 ?m. The solvent-less adhesive contains (i) a polyol component including at least one polyol selected from a polyester polyol, a polyether polyol, and combinations thereof; and (ii) an isocyanate component including an isocyanate prepolymer that is the reaction product of at least one isocyanate monomer and at least one polyol selected from a polyester polyol, a polyether polyol, and combinations thereof. The present disclosure also provides a laminate formed by said process.

A process is provided for treating wood products including lumber, plywood and other engineered wood products comprising the steps of contacting a composition comprising a polypropylene glycol, a high molecular weight polyethylene glycol, a polyether polyol having low solubility in water, or a polytetrahydrofuran, or hydrophobic polyether polyol, with the wood product. The invention also provides wood products comprising a polypropylene glycol, a high molecular weight polyethylene glycol, a polyether polyol having low solubility in water, or a polytetrahydrofuran, or hydrophobic polyether polyol, that have greater dimensional stability compared to an untreated wood product.

Thermosetting epoxy resin compositions on the one hand at room temperature in the incompletely cured state exhibit extremely slight alteration in shape and on the other hand develop a high surface tack, and, moreover, in the fully cured state are of high impact strength and at the same time exhibits high adhesion, particularly to metallic substrates. These compositions are ideally suited to the production of self-adhesive reinforcing elements.

The present invention relates to a curable epoxide/polyurethane hybrid resin system comprising an epoxide resin, a polyurethane and a latent curing agent for the epoxide resin and having a viscosity which makes the hybrid resin system suitable for use in the SMC (sheet molding compound) range. The invention also relates to the use of said resin systems for smc applications, to methods for producing fiber-reinforced composite materials using the claimed resin systems and to the thus obtained fiber-reinforced composite material and construction and moulding materials.

A method for producing a coating on a substrate. The method includes producing a clearcoat directly on the substrate by applying an aqueous clearcoat material directly to the substrate. The method further includes curing the applied clearcoat material, the clearcoat material being a two-component coating composition. Also disclosed are coatings produced according to the method and their uses.
