All-Weather Rain Night Reflective Glass Beads,is a new concept of retroreflective materials. rain night glass beads can greatly inrove the security level of road markings , overcome the defects of traditional markings. its reflectivity is excellent no matter during the day or in rainy nights, which helps to make sure vehicles in line to ensure driver's safety. all weather reflective glass beads is the updated version of ordinary glass beads, it's ideal beads for highways, mountains high ways, uban roads, taxiways, runways and airfields. it's suitable for thermolastic hot-molt coating , water borne paint etc.
All Weather High Reflective Glass Bead/Rainy night glass beads:(Special Glass Beads For Raining Night Road Marking)Normal grade glass beads like 1.5 index works well and it has good reflective result in the nigh time without raining. But in Wet Raining Night, it will be dark.
Application:
(1) Hot-Melt Coating
(2) Double Component Coating
(3) Water Borne Paint
Characteristics :
(1) High Reflective Index in Wet Raining Night
(2) High Retro-reflective more than 350mcd while Durability Of Retro-reflective is more than 150mcd after 1 year
(3) Appearance: All Colors Available: Green, Blue, Red, Yellow, Silver, White
(4) Retro-Reflective index is 350 in dry condition and more than 250mcd in wet raining night.
(5) Gravity: 2.4-2.5g/cm3
(6) Road Marking Line Consumption per Square Meter: 180grams (half of 1.5 index glass beads)
(7) Chemical Composition: TiO2 BaO SiO2 ZrO2
