A bicycle fork including a hollow metal steerer tube connected to a generally hollow unitary crown and blade component made of fibrous resin material. The crown and blades are molded so as to form a continuous structure of fibrous resin material having two opposing wall sections. The inside of the steerer tube is lined with fibrous resin material which is moldedly bonded to the crown to form a continuous and integral unit of fibrous resin material.

Stabilized, catalyzed polyurethane systems are disclosed which are comprised of a polyurethane prepolymer, a tertiary amine catalyst and a stabilizing agent. To extend shelf life, and lend stability to the composition, the stabilizing agent is comprised of methane sulfonic acid. The stabilizer is suitable for use with most polyurethane systems catalyzed by tertiary amines, and produces longer shelf life or stability with lesser amounts than conventional stabilizers. In a particular embodiment requiring extended shelf life but quick curing times, a catalyst yielding these qualities is bis(2,6-dimethylmorpholino)diethylether. The catalyst, when incorporated in a polyurethane prepolymer coated on a flexible substrate, can be immersed in water, the material thereafter being wrapped about the portion of the patient's body to be immobilized, and cures rapidly, within about 15 minutes. The catalyst can optionally be combined with a stabilizer, such as methane sulfonic acid. When stored in the absence of moisture, such systems have exceedingly long shelf life.

Ungelled reaction products of a condensation product with an amino silane are formed. The products are capable of curing at a low temperature to form durable coatings. Polyols can optionally be blended with the ungelled reaction products to provide useful coating compositions.

Film-forming resins containing alkoxy silane groups

High solids thermosetting elastomeric coating compositions are disclosed. The resinous binder of the coating compositions is based on a hard polyester polyol containing cyclic moieties plasticized with a soft polyurethane polyol and cured with a curing agent capable of reacting with active hydrogens, for example, an aminoplast curing agent. The coating compositions are particularly useful on elastomeric substrates such as high density polyurethane foams, as well as on metal substrates such as steel and aluminum.

Elastomeric coating compositions

Described are water reducible coating compositions comprising (A) an organosilane-polyol which is the reaction product of a hydrophilic polycarbinol and an organosilicon material selected from the group consisting of an organosilane, a hydrolyzed and condensed organosilane and mixture, thereof; and (B) a curing agent for the coating compositions.

Coating compositions containing organosilane-polyol

Thermosetting elastomeric coating compositions are disclosed. The resinous binder of the coating compositions is based on a hard polyester polyol containing cyclic moieties plasticized with a blend of soft polyurethane polyols, one of which has a high molecular weight and one of which has a low molecular weight, and cured with a curing agent capable of reacting with active hydrogens, for example, an aminoplast curing agent. The coating compositions are resistant to solvent popping and are particularly useful on elastomeric substrates such as high density polyurethane foams, as well as on metal substrates such as steel and aluminum.
