TEROSON MS 939 black (290 ml)

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.

Processing instructions:

• 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
