Intercoat refers to the coat between the substrate and topcoat, or between any two coats. Normally, the topcoat is applied on the primer and an intercoat coating exists in between the topcoat and primer. The topcoat bonding with the intercoat or substrate depends on intercoat adhesion. Poor intercoat adhesion causes coating failure and leads to corrosion.

The failure of one coat to adhere to an underlying coat is known as “intercoat delamination”.
