    Abstract: A method for preparing a hydrophobic coating by preparing a precursor sol comprising a metal alkoxide, a solvent, a basic catalyst, a fluoroalkyl compound and water, depositing the precursor sol as a film onto a surface, such as a substrate or a pipe, heating, the film and exposing the film to a hydrophobic silane compound to form a hydrophobic coating with a contact angle greater than approximately 150°. The contact angle of the film can be controlled by exposure to ultraviolet radiation to reduce the contact angle and subsequent exposure to a hydrophobic silane compound to increase the contact angle.

    Abstract: An apparatus is provided with a chamber (20) into which a plurality of jets of moisture-laden air is directed through apertures (nozzles) 18. Through the chamber lasted shoes S, on the bottoms of which a coating of a moisture-curable adhesive composition has been applied, are progressively moved, supported bottom uppermost. The velocity of the air, which is re-circulated, is between 10 and 20 meters/second (measured at the apertures), its temperature is between 85.degree. C. and 125.degree.0 C. (measured at the point of impingement on the article) and its dew point not greater than 60.degree. C. The lasted shoes are subjected to this treatment for a period of 1 to 31/2 minutes.

    Abstract: Disclosed is a chamber which defines a constant gas flow environment for passing objects therethrough carried by a conveyor. The chamber comprises an elongate housing having an inlet opening and an outlet opening in the longitudinal direction and a moving conveyor which runs the length of said housing for transporting object from said inlet opening through said housing and thereout through said outlet opening, the space below said conveyor being enclosed and connected to a source of exhaust for exhausting gaseous substances therein. The space above the conveyor comprises an inlet zone, a central gas zone, and an outlet zone. The inlet zone and the outlet zone both are of a bi-cameral containment arrangement comprising an outer adjustable gate for determining the inlet opening, a central adjustable baffle gate, and an inner deflector wall. The space between the outer gate and the baffle gate is connected to a source of exhaust. The space between the baffle gate and the deflector wall is a modulating gas cell which contains a gas knife connected to a source of inert gas and capable of injecting said inert gas at an adjustable angle onto the conveyor substantially its entire width. The central gas flow zone operates under external recycle of its atmosphere in a direction countercurrent to the direction of the conveyor belt which passes therethrough. The chamber is ideally suited for vapor permeation curing of flat substrates coated with a vapor permeation curable coating.

    Abstract: Process for coating flexible substrates which comprises applying a finishing polyurethane-polyurea elastomer coating to a release surface, applying an undercoat of a polyurethane-polyurea elastomer having a different composition than the finishing coating on the finishing coating and applying a flexible substrate to the undercoating.The polyurethane-polyurea elastomers used as the finishing coat are prepared by forming a polyether-polyol prepolymer in which the polyol consists essentially of a diol or a mixture of diols and which prepolymer is subsequently reacted with an aromatic diamine.The polyurethane-polyurea elastomers used to form the undercoat are obtained by reacting the aromatic diamine with a polyether-polyol prepolymer in which the polyol consists essentially of one having an hydroxyl functionality of at least 3 or a mixture of polyols in which at least one of the polyols has a hydroxy functionality greater than 2 in a sufficient amount to increase the resistance to flexing.The coated flexible substrates are useful in many areas as is known for polyurethane or polyurea coated substrates generally, but the coated flexible substrates, according to this invention, are particularly useful in the manufacture of shoe uppers.
