Abstract: A resin composition includes: a polyol (A) having at least two OH groups; a polyfunctional isocyanate compound (B); a catalyst (C); and a compound (D) that undergoes keto-enol tautomerization, in which: a content ratio of the polyfunctional isocyanate compound (B) with respect to 100 parts by weight of the polyol (A) is 1 part by weight to 100 parts by weight; and the catalyst (C) includes an iron-based compound containing iron as an active center thereof. The resin composition can serve as a pressure-sensitive adhesive composition for forming a pressure-sensitive adhesive layer containing a polyurethane-based resin. Also provided are a pressure-sensitive adhesive sheet and a surface protective film each including such pressure-sensitive adhesive layer.

Abstract: A resin composition includes: a polyol (A) having two or more OH groups; a polyfunctional isocyanate compound (B); and a catalyst (C), in which: the content ratio of the polyfunctional isocyanate compound (B) with respect to 100 parts by weight of the polyol (A) is 1 part by weight to 100 parts by weight; and the catalyst (C) includes an iron complex compound. The resin composition can serve as a pressure-sensitive adhesive composition that is a material for forming a pressure-sensitive adhesive layer containing a polyurethane-based resin, the resin composition showing extremely high reactivity without any use of a tin compound as a catalyst, allowing a cross-linking reaction between a polyol and a polyfunctional isocyanate compound to rapidly progress, and being capable of providing a pressure-sensitive adhesive layer having high transparency. Also provided are a pressure-sensitive adhesive sheet and a surface protective film each including such pressure-sensitive adhesive layer.

Abstract: The present invention provides an adhesive tape for surface protection, comprising a substrate and an adhesive layer laminated on at least one surface of the substrate, wherein the adhesive layer is made of an adhesive comprising a polyolefin (a), a hydroxyl group-containing polyolefin (b) and a crosslinking agent (c) having a functional group capable of reacting with the hydroxyl group.

Abstract: The present invention provides an adhesive tape for non-aqueous battery, comprising a substrate and an adhesive layer laminated on at least one surface of the substrate, wherein the adhesive layer is made of an adhesive comprising a polyolefin (a), a hydroxyl group-containing polyolefin (b) and a crosslinking agent (c) having a functional group capable of reacting with the hydroxyl group.

Abstract: The present invention provides a polyolefin-based release agent containing liquid hydrocarbon with viscosity at 38° C. of 5-1500 Pa·s as measured according to JIS K7117-1.

Abstract: The present invention provides a release agent containing at least a nonreactive polyolefin, an aromatic isocyanate having 3 or more isocyanate groups in one molecule and a polyolefin polyol, wherein the content of the nonreactive polyolefin is not less than 80 wt %, and not less than 90 wt % of the nonreactive polyolefin has tensile elasticity at 23° C. of not more than 10 MPa and tensile fracture stress at 23° C. of not more than 8 MPa.

Abstract: Provided is a release agent capable of maintaining the inherent detachability of polyolefin and showing good adhesion to the substrate and a release material using the release agent, and an adhesive tape having such release material. A release agent containing at least a polyolefin, an aromatic isocyanate having three or more isocyanate groups in one molecule, and a polyolefin polyol having a number-average molecular weight of 1500 to 5000.

Abstract: The resin frame includes a fixture frame formed with resin and a net, fixed and extended within the fixture frame. The resin frame with a net is formed by projecting resin so as to enclose a portion of a spread net so as to make the fixture frame, and then by cutting off the net outside of the fixture frame. The cut section made by cutting off the net outside the fixture frame is formed in a groove on the resin frame, and hidden when the resin frame is attached to the framing of a chair. The resin frame with a net formed according to the present invention is visually presentable by ensuring that the cut portion of the net is not easily visible.

Abstract: The present invention realizes spreading a sheet on a frame member by a simple structure and a simple process, and prevents uneven tension charged against the sheet. In the sheet spreading method of the invention, a core member for a backrest of a chair which is heated to around 200° C. in a furnace is put into a flow dipping tank filled with powder resin. As a result, a resin coating is formed on the surface of the pipe constituting the core member. Also, a mesh is placed on a metal mold and clamped. Since a recess corresponding to the shape of the core member is formed in the top side of the metal mold, the mesh is spread on the core member with a tension charged against when the core member having the above-mentioned coating is pressed into the recess.
