Exceptional Fire Resistance and Safety

Terostat MS 939 FR meets stringent fire retardancy requirements, classified to DIN EN 13501-1 B-s1, d0. This ensures low smoke emission and no flaming dropletsmaking it optimal for use in areas demanding heightened fire protection, such as public buildings, transportation vehicles, and marine settings.

Highly Versatile and Reliable Bonding

As an MS-polymer, the adhesive delivers excellent adhesion to a wide range of substratesmetals, plastics, glass, and already painted surfaces. Its superior elasticity and high tensile strength ensure secure, long-lasting bonds even in environments exposed to constant movement or vibration.

Effortless Application and Eco-Friendly Formula

Offering a skin formation in about 15 minutes and a workable paste consistency, Terostat MS 939 FR is easy to tool and apply. Its 100% solvent-free and low-odor formulation makes it environmentally friendly, suited for use in enclosed or sensitive spaces. Paintability expands post-application compatibility.

FAQs of Terostat MS 939 FR Adhesive:

Q: How is Terostat MS 939 FR Adhesive applied for optimal results?

A: Apply the adhesive to clean, dry, and grease-free surfaces using the 310 ml cartridge. A glue thickness of 25 mm is recommended. Tool or smooth the surface within 20 minutes at +23C to ensure proper adhesion and appearance.

Q: What substrates can Terostat MS 939 FR be used on?

A: This adhesive is compatible with most conventional coatings and substrates, including metals, plastics, glass, and painted surfaces, making it suitable for construction, automotive, and marine applications.

Q: When can the bonded parts be handled or painted after application?

A: Initial skin formation occurs in approximately 15 minutes at +23C. Full cure advances at about 3 mm per 24 hours. Once cured, the adhesive can be painted with most conventional coating systems.

Q: Where is Terostat MS 939 FR typically used?

A: It is ideal for use where fire-retardant bonding and sealing are requiredsuch as building construction, vehicle interiors, ship cabins, and other environments needing stringent flame resistance and strong, elastic bonds.

Q: What benefits does Terostat MS 939 FR offer over traditional adhesives?

A: It is 100% solvent-free, has a very low odor, provides excellent UV and chemical resistance, and maintains high elasticity with a tensile strength of approx. 2.2 N/mm, delivering durable and safe bonding even under movement and temperature variations.

Q: How should Terostat MS 939 FR be stored to maintain its quality?

A: Store the adhesive in its unopened cartridge between +10C and +30C. Under these conditions, it retains optimal properties for up to 12 months from the date of manufacture.

Q: What processes should be followed for safe and efficient use?

A: Surfaces must be properly prepared (clean and dry), and application should be performed within the recommended tooling time. The product should be used in accordance with fire safety guidelines due to its intended flame-retardant properties.
