Rainsafe is a specially developed high performance thermoplastic combined with a profiled surface created by imprinting a pattern onto molten thermoplastic to maximise the wet night visibility performance. The imprinted patterns are rotated slightly to the direction of on-coming vehicles. Rainsafe road markings have been developed to be a crucial aid to road safety in dark and wet conditions when road users may be most at risk. The thermoplastic is applied by extrusion or screed method and immediately reflectorised and embossed to create the required profiled marking. The profiled surface of the road marking gives the product superior performance in terms of visibility to road users in adverse conditions, for instance when it is dark and the road surface is wet.
The thermoplastic road marking material is specially formulated to maintain its structure to improve water drainage. As a result, the marking allows light from car headlamps to be reflected to the driver in wet night conditions. The thermoplastic material consists of a mixture of aggregates, fillers, glass beads, pigment and a special binder system.
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 800 g/m2 by a set of bead applicators attached to the extrusion machine.
Lines are tack free within 3 minutes at an ambient air temperature of 15°C.
There are two application methods for Rainsafe material; extrusion by machine, or manually applied screed. After the line is applied to the road it is embossed to produce the regular, repeating Rainsafe pattern.
The application process should be continuously monitored to ensure that all the operating parameters are kept optimised at all times. The nominal thickness of the marking should be 3mm prior to embossment to produce an embossed line between 4 and 5 mm. The marking is completed by a pressurised surface application of solid glass beads.
Where existing markings are being overlaid with this product, the minimum surface preparation of mechanical scabbling is required to promote good adhesion between the two materials.
As edge. lane lines or centre line markings on single carriageway roads. As lane lines on Dual Carriageway / Motorways.
Longer retention of initial retro-reflectivity
Enhanced wet night visibility
Low profile presents no hazard to motorcycles
Good Skid Resistance
Low maintenance costs – single application of sprayed thermoplastic material immediately restores the Luminance & Retroreflective properties of the product.
Selection of imprinted patterns are available.
Compliance with IS EN 1436 & IS EN 1871.
