MF89 one-component silicone structural sealant is a high-performance material known for its exceptional elasticity and high modulus. It can be directly bonded to glass, aluminum alloy, stainless steel, and most common construction materials without the need for additional primers. The sealant undergoes neutral curing, which ensures it is non-corrosive and safe for use on sensitive surfaces. It offers a joint displacement resistance of 25%, making it ideal for dynamic applications. Additionally, it exhibits excellent resistance to atmospheric aging, ensuring long-term durability and performance under various weather conditions.
The main technical specifications include a black appearance after curing, a drying time of 50 minutes, a sag resistance of Zmm, a hardness of 40 Shore A, a tear strength of 6.0 x 10â´ N/m, an ultimate tensile bond strength of 7 MPa, and an elongation of 100%. This product complies with GB16776-97 and ASTM C1184-95 standards. Testing is conducted according to GB/T 13477, GB 531, and ASTM D624.
Installation features include: a) Surface cleaning using the "double cloth" method with a suitable cleaning agent; b) Application of protective tape as per MF881 guidelines; c) Application process using manual or pneumatic injection guns, ensuring even pressure to fill gaps thoroughly, followed by scraping to ensure full coverage; d) Maintaining a glue application temperature above 10°C for optimal results; e) Storage in a well-ventilated, dry area below 27°C for a period of 6 months.
Applications: This sealant is primarily used for the structural assembly of architectural hidden curtain walls but is also suitable for other waterproofing and weatherproof sealing applications. Usage precautions: In addition to the general guidelines applicable to MF881, this product should not be used in completely sealed environments due to the risk of improper curing and potential safety issues.
MF89 is a reliable choice for professionals seeking durable, high-quality sealing solutions that meet international standards and perform reliably in both residential and commercial settings. Whether you're working on large-scale projects or smaller repairs, this sealant provides consistent results and long-lasting protection against environmental factors.
