Project requirements:
-1. Initial retro-reflective is≥450mcd,
-2. Retro-reflective during the application period not less than 150-200mcd.
Using glass beads with a size propotion of 0.3~0.85mm, if the thermoplastic temperature control is not good, it is easy to settle inside the paint, cause a bad retro-reflectivity in initial.
If floating on the paint surface, the retro-reflectivity maybe not bad, but only stay for 3 months.
Add the glass bead grade with 0.85-1.4mm (type3) to extend the glass bead grading to 0.3~1.4mm.
See the surface of the line marking:
Tips: Beads size of 0.85-1.4mm work for the first half of the year’s retro-reflectivity, size of 0.6-1.18mm will work for the middle period, the premix beads 0.3-0.85mm have a continuous retro-reflectivity.
Continuous reflection is no longer a problem.
What is the retro-reflectivity we can achieve? See below pictures:
