    摘要: A golf ball includes an intermediate layer, a cover, and a paint film, wherein a base resin of the paint film is a polyurethane obtained by a reaction between a polyisocyanate composition and a polyol composition containing a urethane polyol including a polyether diol with a number average molecular weight ranging from 800 to 3000 as a constituent component, and the golf ball satisfies the following requirements; Mp≦200×X−75 Mp≦100 Mm−Mc>100 Tm>Tc>Tp (Tm×Mm)/(Tc×Mc)>7.5 (Tc×Mc)/(Tp×Mp)>2.4. [Mp, Mm and Mc represent 10% modulus (kgf/cm2) of the paint film, intermediate layer and cover, respectively; Tp, Tm and Tc represent thicknesses (mm) of the paint film, intermediate layer and cover, respectively; and X represents a molar ratio (NCO/OH).]

    摘要: An adhesive composition is made from a first part containing an isocyanate group-containing prepolymer that is a reaction product of a first isocyanate and at least one polyol; and a second isocyanate that is essentially unreacted with the first isocyanate, the at least one polyol, and the isocyanate group containing prepolymer; and a second part containing at least two polyols; wherein the adhesive composition is essentially free of diluent oils and solvents. A polyurethane adhesive is made by mixing the first part and the second part in a 1:1 to 1.2:1 weight ratio of the first part to the second part to form a mixture, and curing the mixture. The polyurethane adhesive can be used in articles, including semipermeable membranes and reverse osmosis modules. When a solvent is filtered through the semipermeable membranes by reverse osmosis, the polyurethane adhesive prevents or reduces osmotic blistering.
