  • Patent number: 11046849
    Abstract: A thin film that is a result of polyaspartic secondary aliphatic diamines reacted with a low viscosity aliphatic polyisocyanate is provided. A unique feature of the films is the ability to tailor the dry time of this coating. Methods for making the film use a plural component spray machine that has an atomizer and a fluid housing connected to two pressurized and heated component tanks. A polyaspartic ester containing resin and aliphatic polyisocyanate mix through high pressure impingement within the spray machine. A reactant mixture exits the spray machine via the atomizer and forms a film on a surface that is tack free in about 5 minutes.

  • Patent number: 10907051
    Abstract: This invention provides a convenient method of forming and applying a thermoplastic material for roadway markings, comprising: obtaining individual components of a thermoplastic composite material suitable for roadway markings; mixing and heating the individual components to produce a fully compounded form of the thermoplastic composite material; solidifying and prilling the fully compounded form of the thermoplastic composite material to produce a plurality of thermoplastic prills; on a marking vehicle or mobile apparatus, introducing the thermoplastic prills to an on-board melter to produce a liquid phase of the thermoplastic prills; and applying the liquid phase of the thermoplastic prills to a roadway, thereby marking the roadway. Compositions and systems are also described. Surprisingly, prills melt in approximately half the time as the powder/granular form. Also, the melter can be operated at lower temperature, leading to less discoloration of material.

  • Patent number: 10822755
    Abstract: The invention relates to a ground surface marker and method for surface marking. It is known to apply surface markings, for example road markings, using paint. Many current road marking paints have a touch dry time from about five minutes to one hour, with full drying taking 24 hours or more, depending on the air temperature. The dry time of current paints can delay the opening of a road which may be costly because it increases the need for traffic control and can expose contractors to motoring hazards. If roads are opened prior to full drying of the paint, then the road markings may be compromised by contact with vehicle wheels. The invention aims to go at least some way toward addressing these problems by providing a ground surface marker comprising a paint applicator, a dispenser associated with reflectors, and a UV light source.

  • Publication number: 20090176127
    Abstract: The present invention provides fast drying aqueous compositions, suitable for use in making roadway markings, as well as the road markings made therefrom, the compositions comprising one or more anionically stabilized binder having a phosphorus acid functional polymer component having a glass transition temperature (Tg) range of from ?30° C. to 60° C. and a polyfunctional amine component in combination with one or more volatile base in an amount sufficient to stabilize the composition by at least partially deprotonating the polyfunctional amine, and one or more phosphorus acid surfactant, such as an alkyl ethoxylated phosphate. Further, the present invention provides two component compositions comprising the above composition as one component and a second component comprising an absorber and/or the polyfunctional amine component. The fast-drying compositions are viscosity stable and provide wear resistant fast dry coatings even in humid application conditions.

  • Patent number: 7259194
    Abstract: A color agent for a road marking material comprising composite particles having an average particle diameter of 0.01 to 10.0 ?m, said composite particles comprising: inorganic particles; a gluing agent coating layer formed on surface of said inorganic particle; and an organic pigment coat formed onto said gluing agent coating layer in an amount of from 1 to 500 parts by weight based on 100 parts by weight of said inorganic particles. The color agent for a road marking material, contains no harmful elements and exhibits excellent tinting strength, hiding power, light resistance and heat resistance, and is suppressed in surface activity thereof. The road marking material using the color agent, shows a less change in hue with the passage of time and an excellent retroreflective property.
