the reflectance ratio reaches more than 90% and the effective reflection and light shading areas can reach 100% under any condition.
其反射率达90%以上,有效反射遮光面积在任何情况下都能达到100%。
proper selection of the resin, pigments and fillers and additives, especially, a special additive t and formulation lead to the average reflectance ratio is up to 80.
