| description | The invention provides an epoxy modified polyurethane primer, and relates to the technical field of coatings. The epoxy modified polyurethane primer comprises a component A and a component B. The component A is isocyanate, and the component B is prepared from, by weight, 13-25 parts of high-molecular-weight epoxy resin, 5-9 parts of polyether polyol, 18-25 parts of pigment, 4-10 parts of solvent and 1-3 parts of special catalyst. Isocyanate is one of aliphatic isocyanate or aromatic isocyanate, the weight ratio of the component A to the component B is 1: (3.5-4), and the component B further comprises 8-13 parts by weight of inorganic filler. Compared with pure polyurethane or epoxy or acrylic acid primer in the prior art, the epoxy modified polyurethane primer disclosed by the invention has high permeability and high adhesive force, and particularly, the adhesive force is only reduced to a relatively low degree under the condition of a wet base material or long-term soaking.
