HYDRO-PU Chalkboard coating HDB 54611-(colour tone)

High opacity HYDRO-PU Effect lacquer with good coverage and good chemical and mechanical resistance. Its user-friendly flow properties make it very suitable for coating vertical surfaces. Drying leads to the formation of a sophisticated surface that is ideal for writing using blackboard chalks. This blackboard lacquer is light fast, PVC resistant and resistant to creams and perspiration. It can also be used to coat children’s toys as it is methylpyrrolidon-free and free from phthalate plasticisers.
