Abstract

The invention belongs to the field of oil paint, and particularly relates to a 1K gray primer. The gray primer comprises the following components by mass: 30-35 parts of 8150 resin, 5-10 parts of talcum powder, 12-16 parts of NC (nitrocellulose), 20-30 parts of titanium dioxide, 2-6 parts of barium sulfate, 1-1.6 parts of 965 black wash, 30-40 parts of a thinner, 0.4-0.6 parts of a curing agent, 1-2 parts of a defoaming agent, and 1-2 parts of an anti-setting agent. Though the adoption of the technical scheme provided by the invention, the beneficial effect is as follows: the primer provided by the invention has good filling ability and strong adhesive force to connect a substrate with finishing coat. The surface coated with the primer is very smooth without small grains. Therefore, the smoothness of the product is improved, the natural colors of wood can be retained, and the natural colors and the texture of the wood can be prominent.

Description

technical field [0001] The invention belongs to the field of paints, in particular to a 1K off-white primer. Background technique [0002] A primer is a paint that is applied directly to the surface of an object as a solid base for the topcoat. It is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, provide anti-corrosion functions, etc., and at the same time ensure the uniform absorption of the topcoat, so that the paint system can exert the best effect. If the quality of the topcoat is good, the primer can be used. This statement is wrong, because the functions of the topcoat and the primer are different. The topcoat is more focused on the final decoration and appearance effect, while the primer is focused on improving the adhesion and anti-corrosion function. , Alkaline resistance, etc. It is required to adhere firmly on the object surface to increase the adhesion of the upper coating and improve the decorative...
