This invention pertains to coating compositions based on polyesters containing 2,2,4,4-tetrametbyM,3-cyclobutanediol (TMCD) and modifying polyester polyols. Coatings based on such polyester blends are capable of providing a good balance of the desirable coating properties, such as solvent resistance, acid resistance, retort resistance, crazing resistance, and bending ability, for metal packaging applications.

Disclosed is an acoustically and thermally effective engine and/or aggregate capsule which completely encloses the engine and/or aggregate.

There is provided a urethane resin that is excellent in adhesive strength, and maintains high adhesive strength even after exposure to high temperature and humidity. A urethane resin obtained by reacting a glycol-modified aromatic hydrocarbon-formaldehyde resin (A) modified with a glycol with a polyisocyanate (B) having two or more free isocyanate groups in a molecule.

What is described are isocyanate compositions comprising β-dicarbonyl compounds and a binder system, especially for use in a process from the group consisting of polyurethane cold-box process and polyurethane no-bake process, with this isocyanate composition as polyisocyanate component.

The frictional power transmission belt includes a frictional power transmission surface formed of a composite fibrous layer containing a fibrous member, an isocyanate compound, and a resin component, wherein the fibrous member contains a cellulose-based fiber. A proportion of each of the isocyanate compound and the resin component in the composite fibrous layer may be 2 to 15% by mass.

An intumescent coating system contains: a polyol component; an isocyanate component; a latent crosslinker having two or more —NACH.sub.2OR groups, where A is selected from a group consisting of H and —CH.sub.2OR, and in each case R is independently selected from a group consisting of hydrocarbons having from one to four carbons, the latent crosslinker being present at a concentration of 30 weight-percent or more based on polyol weight; a boron component one weight-percent or more and 10 weight-percent or less based on total weight of the formulation; and expandable graphite at a concentration of 10 weight-percent or more and 50 weight-percent or less based on the total intumescent system weight; where the polyol and isocyanate are selected so that the reaction product at room temperature of the intumescent coating system components produces a coating having a tensile elongation of 40-percent or more as determined according to ISO 37.

Resin compositions including (A) a hollow organic polymer particle, (B) an epoxy resin, and (C) a curing agent provide cured products having a superior smear removal properties.
