LOCTITE® 5939™ is a high strength, high elongation adhesive used for elastic bonding and sealing on various substrates. It is a one component adhesive/sealant based on a modified silane polymer, which cures by reaction with moisture to an elastomeric thermoset product. The skin formation and curing times are dependent on humidity, temperature, and joint depth. By increasing the exposure to moisture these times can be reduced. LOCTITE® 5939™ is sag-resistant leading to high initial tack. It is non-corrosive and free of solvents, ***cyanates, silicones, PVC, and is odorless. It demonstrates good adhesion without primer to a wide variety of substrates and is compatible with suitable paint systems. The adhesive/sealant also demonstrates good UV resistance and can therefore be used for interior and exterior applications.
