Product Description
- Teroson® MS 939 is a one-component, moisture-curing adhesive and sealant based on silane-modified polymers (SMP), specifically developed for high-strength and permanently elastic bonding and sealing applications. The product cures to form an elastic, stress-relieving material and is free of solvents, isocyanates, silicone, and PVC. Due to its thixotropic consistency, Teroson® MS 939 offers excellent sag resistance – ideal for vertical applications and overhead work.
- The excellent UV and weather resistance makes it suitable for both indoor and outdoor use. Thanks to its good paint compatibility and broad adhesion to metals, plastics, painted and powder-coated surfaces, Teroson® MS 939 is particularly versatile, for example in the automotive, HVAC, electrical, or plastics industries.

Suitable materials:
Typical application areas:
Substrates must be clean, dry, and free of grease
Primer or mechanical roughening may be necessary
Processing temperature: +5 °C to +40 °C
Application is carried out with a hand or pneumatic caulking gun (290–570 ml cartridges)
Curing occurs through atmospheric moisture; higher temperatures and humidity accelerate the process
- Uncured adhesive can be removed with Cleaner+Thinner A or FL
