Sealer

A sealant is a functional material used to
seal pores, tiny defects, or active groups on the surface of materials. Its core function is to form a dense protective film on the material surface, thereby improving its corrosion resistance, wear resistance, sealing performance, and surface finish. It is widely used in fields such as metal surface treatment, concrete, stone, electronics, and composite materials. It is a key auxiliary material for extending the service life of materials and optimizing product performance.
