Protective Coating to protect new & existing structures from attack by atmospheric chlorides & Carbonation, or from exposure to harmful chemicals. Commonly used materials in non-metallic coatings include polymers, epoxies, and polyurethanes.
It is a simple way to reduce corrosion, by limiting the exposure of the metal to a corrosive environment. Paint is a very common product, but tar, pitch, bitumen, and plastics are also used. An important consideration for protective coatings is to ensure the coating has well adhered to the metal and that it remains intact or is regularly repaired/recoated. Therefore, this product is commonly used to protect culturally significant works, such as outdoor sculptures and architectural elements.
While the cost of damage due to corrosion is much higher than that of more common coating applications, the same type of products are used. Coatings having both chemical and physical intelligence that may offer superior weather ability and act as better barriers to water absorption than commonly used materials, such as waxes and acrylics, are investigated. Our findings indicate that the use of waterborne resins containing polyvinylidene fluoride with Nano clays of Laponite significantly improved performance and may be a viable option in the protection of material cultural heritage.
