Environmental Protection Request to AntiCorrosive Coatings
• With national twelfth five-year-plan exerting, environmental protection and low-carbon become the urgent requests for various field • Anti-corrosive coatings are moving to waterborne (minority of powder) • But properties must be close to solvent-borne anti-corrosive coatings
