Contact cement is a high strength contact adhesive formulated to provide an instant permanent bond between two matting surfaces. Contact cements are used for binding almost all substances including metal, wood, leather, ceramic, rubber, etc. They are also known as drying adhesives. Contact cement is made from elastic polymers such as latex, neoprene or modified chloroprene synthetic rubber, which are dissolved and suspended in volatile solvents such as toluene, hexane, acetone, etc. Contact cements are waterborne contact adhesives that provide strong and tough bonds with excellent hot-creep resistance.
