Publication number: 20240044090Abstract: Embodiments relate to a retroreflective marking system. A retroreflective marking system comprises a colorless binder, colored glass elements, and colored retroreflective elements, wherein the colored glass elements and colored retroreflective elements are positioned on top of the colorless binder such that color and retroreflectivity comes from the top of the system. This system also leads to improved skid resistance.Type: ApplicationFiled: August 2, 2023Publication date: February 8, 2024Inventors: Suruliappa Jeganathan, Jeffrey Lee Stricker, Kevin Goforth

Publication number: 20190241748Abstract: A coating for pelletized thermoplastic road marking material is provided in which at least one of waxes, silica compounds, and inorganic compounds is provided on the surface of the thermoplastic pellet. The pellet is formed by mixing a binder mixture with a filler mixture, heating the mixed ingredients while mixing into a homogenous molten mixture and then extruding the molten mixture. The extruded material is cooled, cut into individual pellets and then coated. The coating prevents clumping of the pellets and also imparts improved flowability and lower melting point properties. Preferred coatings include micronized polyethylene wax, silicates, silanes, silicones, siliconates, fluoropolymers, calcium carbonate and zeolite.Type: ApplicationFiled: April 15, 2019Publication date: August 8, 2019Inventors: Lam Thanh Nguyen, Daniel John Puffer, Suruliappa Jeganathan, Mark Terry

Patent number: 10184048Abstract: A system for dispensing a fast curing epoxy traffic marking composition to a transportation corridor includes a plurality of bins positioned on a transportation corridor marking dispensing apparatus. A first bin contains an epoxy coating which is applied by the dispensing apparatus on a transportation corridor. A second bin contains at least one curing agent which is coated on a carrier such as glass beads or porous silica. These carriers are dropped onto the epoxy coating by the dispensing apparatus and promote rapid curing of the top layer of the epoxy coating while the bottom layer is given additional time to adhere to the roadway surface. This enables the application contractor to open a marked roadway in a quicker manner with less motorist disruption. An optional third bin contains retroreflective beads which are applied to the epoxy coating by the dispenser apparatus to improve visibility of the line marking.Type: GrantFiled: March 4, 2016Date of Patent: January 22, 2019Assignee: Potters Industries LLCInventors: Suruliappa Jeganathan, Chris Davies, Kevin Goforth

Publication number: 20180258292Abstract: A highway marking paint is provided formed from a waterborne latex paint and porous silica beads having a pore volume in the range of 0.3 cc/g to 3.0 cc/g. The silica beads enable the paint to achieve sufficient viscosity to permit the application of a highway marking of at least 40 mil and preferably at least 120 mil. The highway marking paint can also include retroreflective glass beads. Optionally, the highway marking paint further includes an acrylic polymer emulsion. The porous silica in bead form enhances the flowability of the porous silica beads and retroreflective beads.Type: ApplicationFiled: March 10, 2017Publication date: September 13, 2018Inventors: Suruliappa Jeganathan, Kenneth Berg, Neil Miller
