    摘要： A disposable nozzle for an airless, polyurethane spray gun has an inlet chamber section sealingly latched to the gun nose for receiving polyurethane foam components, a mixing chamber section adjacent the inlet chamber containing a static mixer for mixing the polyurethane components and a dispensing tip section adjacent the mixing chamber for discharging the polyurethane as a spray. The dispensing tip has a longitudinally extending passage terminating at a rectangular opening in the tip defined by long side edges and short side edges. The length of the long side edges are generally maintained throughout the tip passage and approximate the diameter of the mixing chamber exit to produce a consistent rectangular fan spray pattern from the nozzle. Spray guide tabs extend from the long side edges of the rectangular tip opening to alleviate nozzle drip during dispensing.

    摘要： There is now provided a polyol composition containing a polyol having polyester linkages and a number average molecular weight of 400 or more, and at least about 8 php of a silicone-containing surfactant polymer. Either mixed into the polyol composition at the time of foaming, mixed into an isocyanate, or both, is an aliphatic or cycloaliphatic C.sub.4 -C.sub.7 hydrocarbon. The polyol composition is used to make a polyisocyanate based closed cell rigid foam by reacting an organic isocyanate and the polyol composition in the presence of an aliphatic or cycloaliphatic C.sub.4 -C.sub.7 hydrocarbon blowing agent.
