Protective Undercoats
Protective Undercoats are designed to be applied to prepared substrates for two main reasons. Firstly to provide adhesion to the substrate for the mid and / or topcoat. Secondly they provide corrosion protection through the use of anti corrosive additives and through the formation of a barrier between environmental conditions and the substrate they are protecting.
