TEROSON® MS 939 is a sag-resistant adhesive polymer formulated free of solvents, PVC, silicones, and isocyanates for its non-corrosive benefits on a wide range of substrates, including metals and plastics. This odorless adhesive is formulated as a high-viscosity, thixotropic paste and is available in white, grey, or black colors.
TEROSON® MS 939 is a thixotropic silane-modified elastomeric thermoset polymer with moisture-curing capabilities for the bonding of side paneling and roof skin bonding applications in interior and exterior vehicle and caravan manufacturing. TEROSON® MS 939 offers a 3 mm depth of cure in 24 hours and achieves skin formation in 4 to 10 minutes without sag. This curing process can be influenced by factors, such as humidity, joint depth, and temperature. It forms a high elasticity bond on a wide range of substrates, attaining 250% elongation at break.
