Described herein are adhesive compositions, and in particular to solventless adhesive compositions, which can be used to construct laminates, such as flexible laminate materials used to construct flexible packaging (among other things). In another aspect, the solventless adhesive materials are essentially monomer and/or catalyst free, making them well suited for use in making laminates for packaged foods, beverages, and other sensitive materials, e.g., materials which should not be contaminated or not contaminated to unacceptable levels. Also described are laminates made with the adhesive compositions. Laminates made with the adhesive compositions exhibit sufficient bond strength to be slit after 4-8 hours after formation and even 4-5 hours after formation.

A golf ball paint composition includes primarily a urethane paint containing polyol as a base resin and polyisocyanate as a curing agent. The polyisocyanate includes two types of isocyanurate and adduct of hexamethylene diisocyanate and the golf ball paint composition has an elastic work recovery of at least 70%. The paint composition has a high self-repairing ability and is of high quality as a golf ball paint. Golf balls coated with this composition are able to maintain a good durability, in addition to which they have an excellent abrasion resistance and an excellent ball appearance.

Provided is a polyurethane foam having excellent heat resistance and the like. The polyurethane foam is obtained from a material that contains a polyol and a polyisocyanate, in which the polyol contains a polyester polyol, the polyisocyanate contains a diphenylmethane diisocyanate-based isocyanate, it is preferable that the polyester polyol has one or more side chains composed of an alkyl group, and the polyurethane foam may be used as a soundproof material for vehicles.

Flexible polyurethane foams having high airflows and excellent viscoelastic properties are made using a polyol mixture that includes a certain liquid polyester, certain ethylene oxide polyols and certain propylene oxide polyols, and a polymeric MDI. When used in applications such as bedding, the high airflows contribute to an improved sense of comfort by the user.
