Title: Innovations by Yukio Nagasaka
Introduction
Yukio Nagasaka is a notable inventor based in Kawagoe, Japan. He has made significant contributions to the field of traffic paint compositions, holding a total of 5 patents. His work focuses on improving the performance and durability of road marking materials.
Latest Patents
One of his latest innovations is a melt-adhesive traffic paint composition. This composition features improved low-temperature stability and includes 20-35% by weight of a dimer acid-modified polyamide resin, 1-5% by weight of a plasticizer, and 30-45% by weight of an inorganic filler. The balance consists of a coloring pigment and a reflective agent. Additionally, it may incorporate a thermoplastic resin such as hydrogenated rosin or a rosin-modified maleic acid resin. The resultant paint demonstrates enhanced low-temperature stability and abrasion resistance, making it highly resistant to the effects of spike tires or tire chains.
Another significant patent is a road marking composition that comprises a resin with a melt viscosity of about 30 to 80 cps at 150°C. This composition includes a modifier made of at least one metal oxide from Groups II and IV of the Periodic Table. The resin options include rosin-modified maleic resin, hydrogenated resin, rosin ester, polyamide, and petroleum resin. The formulation may also contain a polar wax and/or a surfactant, along with various fillers and extenders such as pigments, glass beads, clay, plaster, slaked lime, alumina diatomaceous earth, sand, and plasticizers.
