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 an elastic, stress-relieving material and is free of solvents, isocyanates, silicone, and PVC. Its thixotropic consistency provides excellent sag resistance, making Teroson® MS 939 ideal for vertical and overhead applications.

Its 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 and plastics industries.

Processing instructions:

• Surfaces 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 using a hand or compressed air gun (290–570 ml container)
• Curing occurs through humidity; higher temperatures and humidity accelerate the process
• Uncured adhesive can be removed with cleaner and thinner A or FL
