Study on the curing agent for inorganic zinc-rich lithium silicate coating

In order to enhance the curing speed of inorganic zinc-rich lithium silicate coating and improve the film properties, aqueous solution of lithium silicate was used as the adhesive base material of zinc-rich coating, and a variety of curing agents were added to the zinc-rich paint and base materials. After dip-coating on the surface of iron plate and drying, water-resistant performance tests were taken in the solution of boiling water with 3% NaCI and 5 % NaNO3 respectively. Various ways of adding curing agent and the effects were described, and the mechanism was also preliminarily summarized. The fundamental requirements for the curing agent were proposed, providing a theoretical basis for the selection and application of inorganic zinc-rich coating curing agent.
