What are Protective Coatings
Protective coatings are a simple way to reduce corrosion, by limiting the exposure of the metal to a corrosive environment. Paint is a very common protective coating, 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.
Franklin protective coating is a layer of material applied to the surface of another material with the intent of inhibiting or preventing corrosion.
Franklin protective coating may be metallic or non-metallic. Commonly used materials in non-metallic protective coatings include polymers, epoxies, and polyurethanes. Franklin Protective coatings are 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 types of protective coatings are used. Coatings having both chemical and physical intelligence that may er 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.
