49SF GALLON (2 PACK)
CILBOND 49SF GALLON (2 PACK)
Cilbond 49SF is a one coat bonding system for PU’s and TPU’S to all metals during the curing process. Cilbond 49SF will also bond PU’s and TPU’s to epoxies and fibreglass reinforced plastics, polyamides and other engineering thermoplastics, such as Hytrel®, PBT, PET, PPS, PPO, PEEK, PES, etc.
Cilbond 49SF exhibits good resistance to static and dynamic fatigue and bonds survive in fluids such as fuels, oils including all types of lubricants, glycols, inks, lacquers, paints and many cleaning solvents, though for a maximum resistance to aggressive solvents, the use of Cilbond 49SF and Cilcure B is recommended – see below. (Cilcure B is a liquid form of diphenylmethane diisocyanate with a selected functionality and is used to improve the environmental resistance of bonded parts). Cilbond 49SF has good hot and cold water resistance, as illustrated by tests where polyether/MbOCA or polyester/Ethacure cured compounds bonded to mild steel showed 100% rubber tear when peel tested after total immersion for 28 days in water at 80°C. Bonds made with Cilbond 49SF are impact resistant and not brittle down to at least -40C.
When Cilbond 49SF is used as a 2 part bonding agent with Cilcure B, it has specific benefits and uses, especially for lower temperature bonding and for exceptional resistance to aqueous conditions, such as boiling water and for long-term exposure to predominantly wet conditions. This system is also suited for higher heat resistance to 180C and Cilbond 49SF + Cilcure B is probably more versatile when used as a primer under Cilbond 49SF.
PROCESSING BENEFITS :
Cilbond 49SF exhibits the capability to withstand long pre-bake cycles and with good control of metal preparation and bonding agent application and using extended pre-bake conditions (see below) the bonds can survive up to ca. 130C in static and dynamic conditions.
