Abstract
The invention relates to the technical field of polyurethane primers, and provides a polyurethane transparent primer which comprises a component A and a component B, wherein the weight ratio of the component A to the component B is 1:(0.2-1); the component A is composed of the raw materials in percentage by weight: 50 to 70 percent of basic resin, 1 to 10 percent of granular powder, 1 to 10 percent of a first solvent, 0 to 5 percent of an auxiliary agent and the balance being a filler; the component B is composed of the raw materials: an isocyanate curing agent and a second solvent; the weightratio of the isocyanate curing agent to the second solvent is (2-10):1. The primer is an anti-bottom-biting particle polyurethane transparent primer, and is mainly applied to manufacturing of sealedhigh-grade furniture, wooden doors and other wooden products. The spraying times can be effectively reduced, and the construction period and the use of the coating are reduced.
