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.
