Thermoplastic Paints

 

  • One of the most common and popular types of road markings, due to their right balance between cost, performance and longevity.
  • They are generally based on one of two core binder systems, Hydrocarbons or Resin Esters.
  • Thermoplastic coatings are generally homogeneous dry mixes of binder resins, plasticizers, glass beads, pigments, fillers and additives.
  • Their usage has increased over other types of paints mainly due to the performance benefits of increased durability, retro-reflectivity, excellent adhesion, skid resistance, good visibility, outstanding resistance to traffic wear and abrasion, high softening point (above 95deg. C), environmentally friendly (No Solvent), fast drying time and excellent heat stability.
  • Thermoplastic Markings are applied using special designed machines for application. It is Pre-Heated to 200deg. C before feeding it into the apparatus which is often a screed box, an extruder or a spray gun.
  • Immediately after the thermoplastic is applied, glass beads are shot onto the hot material to embed it into the surface before the plastic hardens.
  • These beads provide the initial retro-reflection and as the marking wears off the initial beads are lost and the beads mixed with the binder are uncovered, providing long term reflectivity.
  • Most thermoplastic paints are produced in White and Yellow colors, but other colors can also be produced on demand.
  • PGPI manufacture thermoplastic road marking paints according to B.S.3262: 1989 (British Standard), AASHTO M249 (American Standard) or any other standard specified by the customer.
