BST-2521 Inorganic Silicon Electronic Nano Waterproof and Heavy Anti Corrosion Coating
BST-2521 Inorganic Silicon Electronic Nano Waterproof Coating is a colorless and transparent single component protective material that utilizes advanced nano ceramic modification technology to form an ultra-thin, dense, and tough ceramic grade protective film on the surface of the substrate. It combines the convenience of organic coating construction with the excellent weather resistance and wear resistance of inorganic ceramics.
IPX8 Ultimate Waterproof:The dense nano crosslinked structure achieves long-term water immersion without permeability, with protective performance far exceeding IPX7 standard, providing military grade waterproof protection for equipment, and is not afraid of moisture immersion.
4H ceramic grade hardness:After curing, the surface hardness reaches up to 4H, effectively resisting daily friction, scratching, and physical impact, reducing shell wear, and significantly extending the service life of precision equipment.
Industrial grade corrosion resistance:Through ≥ 500 hours of neutral salt spray test and 1000 hours of humid heat test, the performance has not deteriorated, perfectly adapting to harsh industrial and outdoor scenes with high salt and high humidity.
Single component design, easy to operate：Ready to use, no need for complex mixing ratios, completely avoiding manual mixing errors. The product has stable storage performance and high construction tolerance, which can greatly simplify the on-site operation process, reduce the professional skill requirements for construction personnel, and effectively improve production efficiency and yield.
