High Performance Spray Thermoplastic Road Markings

Spray Thermoplastic Road Marking Material is an economical and durable rapid dry, 100% solid pavement marking material that, when applied to the roadway with drop-on beads, forms a uniform reflective and durable road marking. The rapid application rate and instant dry times eliminate traffic delays and material tracking normally associated with extruded road markings.

A reflectorised thermoplastic road marking material available in various levels of Luminance, Skid Resistance & Reflectivity.

Spray plastic materials are thermoplastics, which possess lower viscosities than screed/extrusion materials.

Product description

This enables good atomisation at temperatures lower than that at which serious degradation will occur. The application to road surface is achieved by air-atomised spray.

Spray plastic product consists of a mixture of light coloured aggregates, pigment and extender bound together with a thermoplastic binder system.

The exact composition of a Spray plastic grade will depend on the specification requirements, and is designed that when in a molten state, it can be sprayed readily onto the road surface to give an even line of good definition.

Immediately following application of the line, a surface application of solid glass beads to IS EN 1423 or equivalent shall be applied at a typical rate of 450 g/m2 by an applicator gun attached to the spray machine.

Lines are tack free within 1 minute at an ambient air temperature of 15°C.

Application

This process employs a mechanically propelled vehicle. Spray thermoplastic is applied to the road by air spray under pressure through one or more oil jacketed spray plastic guns. The marking is completed by a pressurised surface application of solid glass beads. For more details refer to our Thermoplastic Spray Line Method Statement.

Recommended Thickness 1.0 – 2.5 mm.

Typical Uses

A high output marking for traffic delineation, advisory markings and mandatory markings on all categories of roads. Spray applied thermoplastic is generally used to renew existing road markings.

Features

  • Immediate retro reflectivity
  • Low maintenance costs – single application of sprayed thermoplastic material immediately restores the Luminance & Retroreflectivity of a road marking.
  • High output application volumes.

Compliance with IS EN 1436 & IS EN 1871.
