Patent number: 6838118Abstract: The present invention provides a method for coating bare, untreated metal substrates wherein a coating composition comprising one or more particularly defined additives is applied directly to a bare metal substrate which has not been chemically and/or mechanically altered. The invention provides a method of coating a bare untreated metal substrate. The method requires the steps of (i) providing a bare, untreated metal substrate, the substrate being substantially free of mechanical and/or chemical alterations, (ii) applying a two-component urethane coating composition directly to the bare, untreated metal substrate so as to make a coated metal substrate, and (iii) sanding at least a portion of the coated metal substrate within one hour from the time the two-component urethane coating composition was applied to the bare, untreated metal substrate. The resulting coated metal substrate has an initial adhesion loss of less than 20% as measured by a cross hatch adhesion test per ASTM D-3359 93.Type: GrantFiled: November 12, 2002Date of Patent: January 4, 2005Assignee: BASF CorporationInventors: David L.

Publication number: 20040113378Abstract: A gravity driven steerable vehicle having wheels, or skis or a combination of wheels and skis for recreational use, most particularly on surfaces such as pavement, artificial hard-pack turf, mountain slopes, dirt roads, grass and hard-packed or non-packed snow. The vehicle has at least three (3) but preferably four (4) wheels, or skis or a combination of wheels and skis which may or may not be on independent axles one from the other and which may or may not be each independently shock suspended. There is also a steering mechanism for steering the vehicle and a driver compartment portion for containing a driver of the vehicle in a prone face-down and face-forward position. The vehicle is steerable by the driver from the substantially prone face-down and face-forward position. The mechanism for suspension of the wheels and/or skis is configured to provide precise control in turns especially the carving of turns, by the skis, while descending on snow covered terrain.Type: ApplicationFiled: September 10, 2003Publication date: June 17, 2004Inventors: Frederic L.

Publication number: 20040071887Abstract: The invention provides a coating composition for use with metallic substrates that provides desirable levels of adhesion to metal, sandability without the production of harmful dust, corrosion resistance, and recoatability. The coating composition of the invention comprises a polyurethane film-forming component, and a corrosion protection component present in the composition in an amount effective in minimizing corrosion and adhesion loss of the coating at the substrate. A cured film of the coating applied to metallic substrates, previously coated substrates, as well as plastic substrates has improved corrosion resistance following Salt Spray Cabinet exposure.Type: ApplicationFiled: October 10, 2002Publication date: April 15, 2004Applicant: BASF CORPORATIONInventor: David L.

Patent number: 5204401Abstract: There is disclosed a metallic and nonmetallic water borne base coat compositions exhibiting excellent appearance. A method for long term stability and the introduction of aluminum flake pigments into a water borne coating is also disclosed. The method is based on storing the aluminum flake in a solvent environment with introduction of the aluminum flake in to the aqueous environment just before appling the base coat coating. A water reducible acrylic resin with nonionic and acid functionality derived from vinyl monomers having nonionic and urethane functionality has been disclosed that allows for direct introduction of aluminum flake in to an aqueous environment. The coating vehicle is based on acrylic latex vehicle which exhibits excellent drying and film properties. The rheology control agent employed allows for a wetter application of the coating to the substrate.
