Thermoplastic
road marking paint is in powder/granule form that consists
of light colored aggregate, pigment, extender, binder
and glass bead that becomes liquid when heated at high
temperatures.
The ingredients in the mix do the following:
• The binder is resin or rosin
and plasticizer that hold all ingredients together.
• The pigment supplies the color.
• Glass beads with the pigment provide the retro-reflectivity
and visibility.
• Filler material provides the bulk.
Temperature is the most important factor
in the preparation and application of thermoplastic
road marking paint
• When heated to the recommended
temperature and properly mixed, the dry powder/granules
become a homogenized liquid.
• Then, the melted thermoplastic material, when
applied, forms a thermal bond between the material and
the upper surface of the asphalt.
• Also, if applied on porous surfaces, the melted
thermoplastic material fills all gaps creating mechanical
and thermal bond on concrete and asphalt respectively.
Since the applied thermoplastic material
is raised above the road surface, with the glass beads,
pre-mixed and dropped on, it provide better visibility
at day, night and wet conditions. Thus, contribute significantly
to road safety for all its users.
