COMPOSITION, MARKING AND KIT OF PARTS FOR FORMING A MARKING, SUCH AS A ROAD MARKING

摘要

The disclosure relates to a composition adapted to be applied to a surface (2) to form a marking (1), wherein the composition comprises a base composition (3), and coated glass beads (4), wherein the coated glass beads are mixed with the base composition (3), wherein the coated glass beads (4) are coated with a non-translucent coating material (8) which coating material, when the composition has been applied to a surface to form a marking, is adapted to be worn off at any exposed portion of the glass bead thereby allowing light to enter into the glass bead (6) at said exposed worn off portion and which coating material (8) is adapted to form a retro-reflective coating (8) reflecting light which has passed into the glass bead (6) to be reflected back through the glass bead (6) and out through said exposed portion where the coating has been worn off. The disclosure also relates to a marking formed of said composition, to a kit of parts for forming a marking on a surface and to a marking formed of such a kit of parts.

1. A composition adapted to be applied to a surface to form a marking, wherein the composition comprises
a base composition, and coated glass beads,
wherein the coated glass beads are mixed with the base composition,wherein the coated glass beads are coated with a coating material which coating material, when the composition has been applied to a surface to form a marking, is adapted to be worn off at any exposed portion of the glass bead thereby allowing light to enter into the glass bead at said exposed worn off portion and which coating material is adapted to form a retro-reflective coating reflecting light which has passed into the glass bead to be reflected back through the glass bead and out through said exposed portion where the coating has been worn off,wherein the coating is non-translucent, andwherein the coating, when coated on premix glass beads according to EN1424 class A having a size within 180 and 600 μm and with the coated glass beads being provided in an amount of 30% by weight in a non-pigmented reference composition, will produce a reflectivity of at least 100 mcd/lux/m2 measured at a wear simulator turntable according to EN 13197 at traffic class P4.
