Extrusion thermoplastic product consists of a mixture of light coloured aggregates, pigment and extender bound together with a thermoplastic binder system.
The exact composition of an Extrusion thermoplastic grade will depend on the specification requirements, and is designed that when in a molten state, it can be extruded onto the road surface to give an even line of good definition.
In order to give good drainage characteristics, a drainage channel may be incorporated into the line at predetermined intervals.
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.
