Abstract
The present disclosure develops a water-based peelable coating that can be colored and that when drying at room temperature makes it possible to temporarily protect various surfaces and their manufacturing processes. Notably, the present invention relates to a coating designed by using exclusively naturally occurring polymeric materials, which can be applied by various methods and be used outdoors or indoors on clear, rough and smooth substrates, except woven materials, so as to provide protection and beautification.
