Abstract
Provided is a composite resin composition for steel plates for a fuel tank, including: 30 to 65% by weight of a polymer resin; 1 to 15% by weight of a curing agent; 2 to 20% by weight of a corrosion-resistant additive; 1 to 15% by weight of an adhesion promoting agent comprising a polyphosphazene polymer compound; and a residual solvent. A composite resin-coated steel plate for a fuel tank, and a manufacturing method for a composite resin-coated steel plate are provided.
