For elastic bonding and sealing on dissimilar substrates, there’s TEROSON® MS 5570. This high strength, high elongation adhesive is based on a Flextec polymer, which cures by reaction with moisture to an elastomeric thermoset product (definitions in FAQs). The skin formation and curing times are dependent on humidity, temperature, and joint depth, but you can reduce these times by increasing the exposure to moisture. The product is sag resistant, has a high initial tack, and is non-corrosive. It’s also odorless and free of solvents, isocyanates, silicones and PVC. You can expect good adhesion to a wide variety of substrates and compatibility with suitable paint systems. Its good UV resistance makes it ideal for both interior and exterior applications.
