Abstract
Water-based stains comprise or consist essentially of a polysaccharide resin and a crosslinking agent such as an isocyanate. Upon evaporation of water, the polysaccharide undergoes crosslinking with the isocyanate component, developing water resistance so that it will not redissolve upon application of a water-based or oil-based clearcoat; as a result, lifting is minimized after a drying time of, e.g., two to six hours.
