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.
- 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.
- 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.
