Kraton polymers exhibit the superior performance needed to produce long-lasting hot-melt applied thermoplastic road marking paints. When added to paint binders, tough Kraton™  G SEBS and Kraton™  D styrene-isoprene-styrene (SIS) polymers improve coating strength and mechanical properties, reduce the paint erosion after numerous wheel passages and enhance the adhesion to glass beads resulting in superior retro-reflections properties.  In addition, Kraton polymer-based binders resist cracking and maintain elasticity at temperature extremes on a variety of road surfaces.

Features and Benefits

  • Improved abrasion
  • Superior crack resistance
  • Elasticity at elevated temperatures
  • Flexibility at low temperatures
  • Exceptional retro-reflection (UV stability)
  • Balanced cohesion / adhesion
  • Improved glass bead retention
  • Excellent oil retention
  • Hot melt stability
