Cilbond® 12E is a solvent-based primer with high-temperature resistance. It provides excellent corrosion resistance and substrate protection. It is used in conjunction with CILBOND 80ET as a high-performance primer for rubber-to-metal bonding. It offers outstanding temperature resistance, glycol resistance, and corrosion performance, making it suitable for high-temperature and aggressive environments. It is commonly used in the manufacturing of high-performance rubber-to-metal bonded parts in industries such as agricultural and construction machinery, MRO (maintenance, repair, and operations), aerospace, and automotive.
