The Characteristics of a quality SALLY Thermoplastic Road Marker – It consist of a mixture of Pigments, glass beads, binder and filler materials
Excellent Adhesion:
The selective combination of high grade resins coupled with the hot
applied method of the material provides an extremely strong bond between
the material and the road surface substrate.
 |
Good Day & Night
Visibility:
A 20% intermix complying BS6088 of high
quality reflective glass beads provides continuous retroreflectivity
throughout the life span of the material. For immediate effective
high retro-reflectivity, drop-on beads are being recommended at the
rate of 400gm/Sq.m. Skid
Resistance:
Aggregate materials of selected sizes are used in the product
mixture and tested thoroughly to provide maximum required skid
resistance for better road safety. The skid resistance of white or
yellow marking material, shall not be less than 45% as per BS
3262. |
|
Fast Drying Time: The
product dries within 3 (three) minutes after application, and
traffic can be released in 5 minutes. This is most vital in busy
traffic areas, thus avoiding serious traffic
congestions. Colour Brilliance and
Outstanding Whiteness:
Due
to selective use of high quality hydrocarbon resin, titanium dioxide
(rutile grade) and high temperature resistant chrome pigment, the
end results are most outstanding both in unique whiteness and colour
brilliance synonymous with Sally Thermoplastic

 |
 |
Product Stability: By careful selection of high quality raw materials combined with the improved chemical formulations obtained through years of research and development, the product is able to maintain its stability against effects of ultra violet rays of the sun, thus retaining its original colours or whiteness and physical conditions for a long period of time.
Good Flow Property: Sally Thermoplastic is relatively easy to preheat to melt thus shortening the start-up time. When maintained at 180°C to 200°C preheating temperature, it gives a good flow property against viscosity which is important to give well defined lines and at the same time retaining the required thickness of lines. | |
|
High Softening Point:
The Softening point of the screed materials as measured by the ring and ball method shall not less than 65°C Outstanding Product Characteristics: A good chemical formulation combined with years of R & D has yielded a product of exceptional stability against the effects of the U/V ray and the harsh tropical climatic conditions.
|
|
Reflectorization: High retro-reflection is
obtained through the mixing of high quality spherical glass beads
(20% of mixture by weight) into the formulations thus giving
excellent visibility to drivers day and night. For immediate
reflectorization,. It is recommended that glass beads be sprinkled
onto the surface of the lines or markings as they are drawn at the
rate of not less than 400g/m2. Special Formulation: For countries with four seasons or extreme cold temperature, a special chemical formulation is used to cater for varying conditions of changing temperatures. |
