Two-part cyanoacrylate compositions, methods for making same, and uses therefor are described. The compositions can be used to bond a variety of substrates including plastics and metals. The compositions remain effective after thermal ageing and humid ageing.

The spray can with pre-mixed fiberglass and resin is a prepackaged application system for fiberglass, which can be used for repair or for new applications. The spray can with pre-mixed fiberglass and resin is a chemical formulation that contains a combination of fiberglass and resin that can be applied in a single coat or a multiple coat in a manner similar to applying paint through a spray paint can. The spray can with pre-mixed fiberglass and resin comprises fiberglass, a solvent, a resin, and a propellant.

An adhesive and solid particulates adhered to the pads of an animal's paw, the adhesive being cured, thereby increasing the friction of the surface of the pads; and a method of increasing the friction of an animal's paw by applying to clean, dry pads of the animal's paw a layer of uncured adhesive, and while the adhesive layer is uncured, contacting the paw with particulates to adhere the particulates to the pad, then curing the adhesive.

An object of the present disclosure is to provide a thickener that can be suitably used as a thickener for adhesives and is excellent in long-term stability when it is used in the application of a thickener for adhesives, particularly when used in cyanoacrylate-based adhesives. A thickener contains a methacrylic resin having an Mw of 85,000 to 1,500,000, wherein 1 and 2 satisfy 1.02/15.0, where 1 is a viscosity (Pa.Math.s) of a solution of the methacrylic resin in ethyl cyanoacrylate at 25 C., and 2 is the viscosity (Pa.Math.s) of the solution at 25 C. after cooling when the solution is allowed to stand at 60 C. for 48 hours to cool to 25 C. (where the concentration of the methacrylic resin in the solution is 20 mass %, 10 mass %, or 7 mass %, depending on the Mw of the methacrylic resin).
