Chemlok 259 Adhesive
Covercoat adhesive for bonding uncured rubber to metal
Chemlok 259 is a versatile covercoat adhesive designed to create a strong bond between uncured rubber and metal substrates during the vulcanization process. Its effectiveness is enhanced when used with Chemlok 207 primer. The adhesive exhibits excellent resistance to a wide range of chemicals, environmental factors, and high temperatures, making it suitable for demanding applications. Proper surface preparation is crucial for optimal adhesion.
