CONSTRUCTION METHOD
1.Clean the surface of the materials to be bonded with solvents or other methods.
2.Cut the tip to the corresponding size according to the gap need filling and other requirements. Apply the sealant evenly by glue gun, ensuring that the sealant contact with the substrate and filled completely.
3.Adjust and repair before the sealant has fully cured.
STORAGE
Stored in a dry place at 0~27°C, and keep them in a well-sealed state.
SHELF LIFE
12 months
SAFETY
Keep out of reach of children. Before operation, please carefully read the specifications of products and material, and instructions on the package of container.
For more information about safety, please refer to the MSDS.
STANDARDS
Hisil company is certified to ISO9001/ISO14001 standards, and recommended by the China Curtain Wall and Metal Structure Association and the National Building Decoration Association.MS Sealant, also known as Modified Silicone Sealant or MS Polymer Sealant, is a high-performance hybrid material that combines the best properties of silicone and polyurethane technologies. It is widely used in construction, automotive, marine, and industrial applications for sealing, bonding, and waterproofing purposes. Known for its strong adhesion, flexibility, and environmental resistance, MS Sealant has become a preferred alternative to traditional sealants.
One of the key advantages of MS Sealant is its excellent adhesion to a wide variety of substrates. It bonds effectively to materials such as concrete, metal, glass, wood, plastics, and ceramics without the need for primers in most cases. This makes it highly versatile and suitable for both indoor and outdoor applications across different industries.
Flexibility is another important feature of MS Sealant. It maintains elastic properties even after curing, allowing it to accommodate structural movement, expansion, and contraction without cracking or losing adhesion. This makes it ideal for joints, gaps, and connections where movement is expected, such as building facades, window frames, and flooring systems.
Weather resistance is a major benefit of MS Sealant. It is highly resistant to UV radiation, rain, humidity, and temperature fluctuations. Unlike some traditional sealants, it does not degrade, shrink, or become brittle when exposed to harsh environmental conditions. This ensures long-lasting performance and reliability in both residential and commercial applications.
MS Sealant also offers excellent waterproofing capabilities. It creates a durable, watertight seal that prevents moisture penetration and protects structures from water damage. This makes it ideal for use in bathrooms, kitchens, roofing systems, and exterior joints where water resistance is critical.
Another significant advantage is its eco-friendly formulation. MS Sealant is typically free from solvents, isocyanates, and harmful chemicals, making it safer for both users and the environment. It has low VOC emissions, which contributes to healthier indoor air quality and compliance with environmental regulations.
Durability is a key characteristic of MS Sealant. It maintains its performance over long periods without losing elasticity or adhesion. This reduces the need for frequent maintenance or replacement, making it a cost-effective solution for long-term sealing and bonding applications.
Ease of application is another important benefit. MS Sealant can be applied using standard caulking guns and tools. It has smooth extrusion properties and good workability, allowing for clean and precise application. It can also be painted after curing, providing flexibility in design and finishing.
MS Sealant is widely used in construction projects for sealing expansion joints, bonding panels, installing windows and doors, and waterproofing roofs and walls. It is also used in prefabricated and modular construction systems, where reliable sealing and bonding are essential for structural performance.
In the automotive and marine industries, MS Sealant is used for bonding components, sealing joints, and preventing water ingress. Its vibration resistance and flexibility make it suitable for dynamic environments where materials are subject to movement and stress.
Another advantage of MS Sealant is its compatibility with various surfaces and coatings. It does not cause staining or corrosion on most materials, ensuring clean and professional finishes. This makes it suitable for visible applications where appearance is important.
Customization options are available to meet different application needs. MS Sealant comes in various colours, curing speeds, and performance grades, allowing users to select the most suitable product for specific requirements.
From a cost perspective, MS Sealant offers excellent value for money. Its long lifespan, minimal maintenance requirements, and high performance reduce overall lifecycle costs. It is an economical choice for both small-scale and large-scale projects.
In conclusion, MS Sealant is a versatile, durable, and high-performance solution for sealing, bonding, and waterproofing applications. With its strong adhesion, flexibility, environmental resistance, and ease of use, it provides a reliable alternative to traditional sealants. Whether used in construction, industrial, or general-purpose applications, MS Sealant ensures long-lasting and effective performance.
