A polymer blend suitable for use in automotive floor covering applications includes 100 parts by weight of a radial block copolymer having the general formula (AB)BA, wherein n is greater than 1, each block A is a monoalkenyl arene polymer block and each block B is an elastomeric conjugated diene polymer block; from about 5 to about 200 parts by weight of a mineral oil; and from about 5 to about 300 parts by weight of a 1-olefin polymer. The resulting polymer blend may be formed into sheet materials which are recyclable, and which may exhibit low gloss and excellent tactility similar to vulcanized rubber. Further, the polymer blends of this invention may exhibit excellent grain retention, abrasion resistance, heat stability, and ultraviolet light stability.

Polymer blend for automotive flooring applications

A window panel assembly to be bonded to a vehicle body opening using a conventional, window fixing urethane adhesive disposed between the vehicle pinch-weld flange and a polymeric gasket attached to the window panel. The joint produced between the window fixing adhesive and the polymeric gasket has a bond strength and performance greater than that achieved in conventional metal-to-glass bonds using the same fixing adhesive. The panel assembly of this invention may be sent to the automobile manufacturer so that all the installer needs to do is apply the window fixing adhesive between the gasket and the vehicle in a conventional manner. The strong bond can be achieved even after the panel assembly has been in storage for days, weeks, or even several months prior to installation. The panel assembly includes a gasket bonded to a sheet-like panel and having a surface adapted to receive a window fixing adhesive for bonding the sheet-like panel in the vehicle opening. An adhesion-promoting compound is applied to the gasket surface and heated to a transition temperature of at least about 60.degree. C. When raised to at least this temperature, the adhesion-promoting compound and gasket bond with the fixing adhesive when the window panel assembly is installed. A load exerted on the joint sufficient to cause a failure results in a cohesive failure of the gasket, the fixing adhesive, or both, but not of the adhesion between the gasket and fixing adhesive. A method is also provided for making the panel assembly of this invention.

Gasketed panel

A vehicle window panel assembly and a manufacturing method for such assemblies having a gasket made from a melt-processible material and providing a long-term, failure-resistant bond between the gasket and window panel for retaining the window panel assembly in the vehicle. The gasket material provides a bond which resists both short- and long-term dynamic and static loads exerted on attachment members embedded in the gasket to prevent failure or separation between the gasket member and the window panel assembly for prolonged assembly life and substantial saving to vehicle manufacturers and owners. A method for identifying and selecting the melt-processible material for forming the gasket member is also disclosed.

Method for making a vehicle window panel using a melt-processible gasket

A panel assembly and method for manufacturing the panel assembly, especially adapted for use in vehicles, includes a panel of predetermined size and geometry wherein a surface of the panel to receive a gasket is primed using a material especially adapted to prepare the panel surface to bond with the gasket. The desired gasket profile is molded separately from the panel from a polymeric material. Following formation of the gasket, the panel is located thereon and pressed into intimate contact with the gasket for a prescribed period of time. The panel and attached panel are removed as an assembly. Additional or optional steps may be followed including preheating the panel and primed surface prior to bonding to shorten the cycle time and improve adhesion. Moreover, heat may be applied to the contact boundary between the panel and gasket substantially simultaneously with the application of pressure. The steps of heating and applying pressure may be repeated to insure proper adhesion. The panel assembly and the method of manufacturing the panel assembly are especially adapted for use in flush mounted panel assemblies wherein the gasket is fixed only to a single surface of the pane and allows for gradationally varying cross-sectional profiles to specifically suit a needed application.

Method for making vehicular panel assembly

A method for bonding an attachment member to a substrate substantially simultaneously with the formation of a sealing member, and a panel assembly made according to the method. The method includes the steps of applying an adhesive to either the attachment member or the substrate, or both, and holding or otherwise retaining the attachment member against the substrate. A sealing member is deposited on the substrate and encapsulates at least a portion of the attachment member. Heat, generated by the polymeric material or added by an external source, causes the adhesive to cure, creating a strong secure bond between the attachment member and the substrate. The attachment member may then be used to mount the substrate to another surface and securely fixed thereto by an adhesive adapted to bond the surface and attachment member together.

Glazing using a melt-processible gasket material

Vehicular panel assembly and method for making same

A panel assembly and method of manufacturing the panel assembly, especially adapted for use in vehicle panels, include locating a preformed gasket in a support fixture in a predetermined pattern to be bonded to a sheet-like panel. The gasket is formed from a polymeric material separately from the panel. The panel is of appropriate size and geometry to fit within a desired vehicle opening. At least one panel surface to receive the gasket is prepared by being primed with a bonding reagent. The panel and primer may be preheated before receiving the gasket to drive off remaining carriers/solvents and improve the bonding process. The panel and preset gasket are pressed together such that the securing flange is in intimate contact with the panel. Locator pins may be used to properly position the panel with respect to the gasket. Once located, heat and pressure are applied, preferably substantially simultaneously, the heat being applied from a side opposite the primed surface, preferably by focused or tuned infrared irradiation.

Method of making a vehicle window assembly

The present invention comprises a vehicle accessory mounting button, windshield arrangement and a method for making the same which uses nonelastomeric, thermosetting, structural adhesives, preferably in film form, to adhere the accessory mounting button to the interior surface of a windshield. The adhesives provide outstanding long-term adhesion and good accessory assembly vibration performance even under rigorous climate conditions while simultaneously being compatible with conventional autoclaving processes used in windshield manufacturing. Thermosetting structural adhesives suitable to achieve the objectives of this invention include modified epoxies, which have a cure temperature below 325.degree. F., a modulus of elasticity at 85.degree. C. of at least about 10,000 psi when cured, and are compatible with current windshield manufacturing processes.

Interior rear view mirror mounting system utilizing one-package

A safety-enhanced, inside rearview mirror assembly for vehicles of the type adapted for movement between day and night positions to reduce reflected glare is disclosed. The assembly includes an energy/impact absorbing plate selected to have predetermined thickness, stiffness, cracking/permanent deformation resistance, and galvanic action passivity positioned between the glass mirror element and the day/night actuator within the mirror case. The plate absorbs the actuator impact energy should the day/night actuator be caused to impact the rear of the glass mirror element when the front of the inside rearview mirror assembly is contacted by an air bag during deployment in an accident and substantially reduces damaging protrusion of glass shards which otherwise could puncture and impair proper operation of the air bag. The plate may be spaced from the rear of the mirror element, or adhered to the mirror element preferably with a flexible, resilient adhesive laminate which doubles as an anti-scatter layer. The plate avoids significant affects on the weight, vibration, and mirror case construction without degrading the light reflective layer.
