  • Method of producing wear resistant traffic markings
    Publication number: 20030224184
    Abstract: A method is provided for producing wear resistant traffic markings. The method includes the application of a traffic paint composition containing select copolymer particles bearing acetoacetyl moieties and aminosilane. Also provided is a traffic marking prepared by the method of the present invention. The method allows the preparation of wear resistant traffic markings with low levels of aminosilane relative to the level of the acetoacetyl moieties.

  • Coating composition having extended storage stability and method for producing wear resistant coatings therefrom
    Patent number: 5939514
    Abstract: The present invention relates to the preparation of water based coating compositions having extended storage stability. The composition includes separately stored polymeric binder component and a crosslinking component.These components are mixed prior to application over surfaces, such as, road surfaces. The polymeric binder component includes an anionically stabilized binder polymer having at least one reactive functional pendent moiety, or a blend of the binder polymer with a polyfunctional amine. The pot mix of the coating composition has extended storage stability. The waterborne road marking paints of the present invention exhibit improved wear resistance on road surfaces in terms of paint remaining on the road longer than waterborne road marking paints based on the storage stable component alone. The present invention provides road marking paints that can be applied by conventional road striping equipment and do not require special two component spray equipment.

  • Method of producing wear resistant traffic markings
    Patent number: 5820993
    Abstract: The present invention is directed to a method of producing wear resistant traffic paint composition. In accordance with the method, a traffic marking of a traffic paint composition having low GPC number average molecular weight latex binder when applied to the road surface exhibits improved wear resistance over those traffic paint compositions having high GPC number average molecular weight latex binders. The wear resistance is further enhanced by modifying the latex polymer used in the composition with acetoacetyl functional pendant moiety and amino silane.

  • Shelf stable fast-core aqueous coating
    Patent number: RE36042
    Abstract: A shelf-stable fast-cure aqueous coating is disclosed. The coating contains an anionically stabilized latex, a polyfunctional amine and a volatile base in an amount sufficient to deprotonate the conjugate acid of the amine.
