Teroson MS 939 black (290 ml)

Product description:

Teroson® MS 939 is a single-component, moisture-curing adhesive and sealant based on silane-modified polymers (SMP) that has been specially developed for high-strength and permanently elastic bonding and sealing applications. The product cures to an elastic, stress-equalizing material and is free of solvents, isocyanates, silicone, and PVC. Thanks to its thixotropic consistency, Teroson® MS 939 offers very good stability—ideal for vertical applications and overhead work.

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 and can be used in a wide range of applications, for example in the automotive, air conditioning, 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
• Processing is carried out using a hand-held or pneumatic spray gun (290–570 ml container).
• Curing through air humidity; higher temperatures and humidity accelerate the process
• Uncured adhesive can be removed with Cleaner+Thinner A or FL.
