AASHTO M 249 Thermoplastic Road Marking Paint with 30% Glass Beads
High Reflective
Description
Thermoplastic road marking paint, also called hot melt marking
paint, is a kind of powder paint. When applied as road surface
markings, a hot melt kettle is used to heat it to 200°C, after
which it is sprayed on the road surface. The coating then becomes a
line after cooling. This paint is thick coating, wear-resisting,
bright and reflective. In recent years, practical applications have
proved that the marking lines lack certain surface roughness and
can easily cause wheel slip, resulting in a traffic accident in
snow and rainy weather. Therefore, some countries once restricted
the use of this paint. In order to increase the anti-skid
performance of the line, thermoplastic paint has added reflective
glass beads. Thermoplastic can be used very effectively for large
Anti-skid areas on roads and pedestrian walkways by adding glass
beads. It can be produced in any colour and is great for car parks,
factory walkways and many other areas. It's fast drying and can be
driven over after just a few minutes. Components of thermoplastic
marking paint is mainly composed by synthetic resin, glass beads,
pigments, packing materials, additives, etc. Synthetic resin has
thermoplasticity, make the hot melt coating fast dry and strong
adhesive to the road surface. Additives in the paint can increase
the plastic of the coating, and make it resistant to subsidence,
pollution and color fading. Pigments: the common colors of road
lines are yellow and white. White pigments are mainly titanium
dioxide, zinc oxide, and lithopone, while yellow pigment is mainly
heat-resistant yellow lead. Packing materials, as filling added
into the paint, ensure mechanical strength, wear resistance, and
color of paint coating. The particle size will affect liquidity and
precipitation, as well as the surface processing. Glass beads are
added in order to improve the identification of lines at night, to
improve the brightness and durability of the marking. Glass bead is
colorless and transparent ball, has function of light refraction,
focusing and directional reflection. Glass bead mixed in the
coating or dispensed throughout the coating surface can reflect car
light back to the driver's eyes, thus greatly improving the marking
visibility.
