Road Markings

Thermoplastic Spray Line – Product Specification

Description

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

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

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

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.

Typical Uses

A high output marking for traffic delineation, advisory markings and mandatory markings on all categories of roads

Packaging

Spray Thermoplastic is supplied in 25kg low melt polythene sacks. Each bag is 25kg of powder mixture and supplied in 1.5 tonne batches, covered and stretch wrapped for protection.

Binder

  • Enhanced wet night visibility
  • Immediate retro reflectivity
  • Low maintenance costs – single application of sprayed thermoplastic material immediately restores the Luminance & Retro reflective.
