Abstract: The present invention provides a method for preparing a glass substrate with antireflection functionality by applying a coating formulation that affords antireflection effects to a substrate comprising water, metalloid oxide nano particles that are dispersed in said water, and a hydroxide ion agent or fluoride ion agent that is introduced into said metalloid oxide nano particles at a mole ratio of 0.005˜2:1. The coating formulation of the present invention enables manufacture of a porous nano antireflection film with high transmittance following a more streamlined process than the prior art, obtaining an antireflection film with a high adhesive force between the film and substrate, and high durability by increasing particle-particle bonding and the bond strength between particles and substrate.

Abstract: A golf club head (20) having a body (22) with a front wall (30) with an opening (32) and a face component (40) is disclosed herein. The face component (40) has a striking plate 41 and a return portion 43. The return portion (43) creates a sandwich structure (70) with edges (75 and 77) of the body (22). The body (22) is preferably composed of a light weight non-metal material. The golf club head (20) preferably has a volume between 300 cubic centimeters and 600 cubic centimeters. The golf club head (20) preferably has a mass between 105 grams and 300 grams.

Abstract: The present invention provides a hollow golf club head comprising a metal striking insert and a composite body. The metal striking insert (1) is molding within the front face wall (2) of the club head body and is securely attached at the outside perimeter of the insert to the composite body and at the front corners of the composite body through the use of a sandwiched structure (7,8, &9). The sandwich structure formed at the boundaries of the striking metal insert efficiently dissipates the impact energy affected when a golf ball is hit. The structure also dampens efficiently the vibrations of the shock affected when the ball is hit on the metal striking insert. The present invention of positioning the insert inside the face wall, not extending outside the face wall, uses less metal material which is heavier than the composite material and makes a larger club head at the same total weight of the club head.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
