WATER BASED COMPOSITION COMPRISING LIGHT DIFFUSION PARTICLES AND A POLYURETHANE RESIN

摘要

The present invention concerns a water based composition comprising at least light diffusion particles and a polyurethane resin, notably between 10 and 40% by weight of light diffusion particles and between 5 and 30% by weight of a polyurethane resin. The invention also concerns a method for coating at least a part of a surface, preferably the surface of a transparent substrate, comprising at least the step of a) applying the composition of the invention on at least a part of the surface and b)carrying out the coating forming on the surface. The present invention also concerns a LED assembly comprising at least a LED light source component and a transparent substrate having at least a part of the surface coated by a composition comprising at least light diffusion particles and a polyurethane resin.
