Etchprimers are economical single pack phenolic, vinyl butyral based product containing anti-corrosive pigments. They dry to a semi matt finish and are used as fast drying pre-treatment primers to applying the full paint system. They are particularly suitable as afterblast primers. Thin films are weldable and suitable for flame cutting.
They also exhibit good adhesion and flexibility. These products can be overcoated by a variety of systems. They are also suitable for aluminium and suitably prepared zinc.
