NOVELTY - High temperature nano-identification coating capable of prolong substrate life comprises 30-45 wt.% nano-silicon oxide, 10-16 wt.% nano-aluminum oxide, 2-6 wt.% nano-silicon carbide, 3-5 wt.% nano-zirconium oxide, 0.1-0.3 wt.% nano-ferric oxide, 0.8-3.1 wt.% nano-magnesium oxide, 0.5-2.3 wt.% nano-zinc oxide, 7-12 wt.% binder, 5-10 wt.% oxidized graphene, 2.1-3.6 wt.% isocyanate, 1.2-3.2 wt.% surfactant, 1.6-2.7 wt.% silane coupling agent, 1.3-4.1 wt.% barium sulfate, 4.2-8.3 wt.% hollow glass beads and 3-7 wt.% cuprous oxide. USE - Used as high temperature nano-identification coating capable of prolong substrate life. ADVANTAGE - The nano-identification coating improves the antibacterial performance of the coating by adding cuprous oxide, avoids the damage the coating caused by mildew accumulation, and prevents the influence to the service life of the inner substrate.
