Ri 1.9

Category: Road Traffic Products Line

By using high-refractive-index optical glass (RI > 1.9), the product boasts enhanced brightness and reflectivity. Compared to traditional glass-bead markings, it offers significantly higher reflectivity, with a reflection visibility range that meets the distance requirements for aircraft pilots during takeoff and landing. This product is suitable for road markings in a wide variety of application scenarios and can be applied using conventional construction methods and equipment with all types of marking paints.

Detailed introduction

  By using high-refractive-index optical glass (RI > 1.9), the product achieves highly reflective performance. Compared to traditional glass-bead markings, it offers significantly higher reflectivity, with a reflection visibility range that meets the distance requirements for aircraft pilots during takeoff and landing. This product is suitable for road markings in a wide variety of application scenarios and can be applied using conventional construction methods and equipment with all types of marking paints.

 

Application areas

  For areas requiring enhanced road markings and meeting special requirements—such as airports, ship decks, landing strips, sharp highway curves, zebra crossings, schools, hospitals, and others—road markings with higher retroreflective coefficient levels are necessary.

 

Product Features

  • Using high-refractive-index optical glass (Ri > 1.9) results in higher reflectivity compared to conventional road markings.
  • The markings have a longer visibility range and a wider application scope, making them suitable for various scenarios and all types of marking paints.
  • The surface is smooth, has good fluidity, and is easy to work with.
