MS Hybrid Sealant Usage
- The best environmental conditions for the construction of the sealant are temperature 4 ℃ ~ 40 ℃, relative humidity of 40% ~ 80%.
- Clean the surface of adhered or coated objects before use, and use suitable solvents including anhydrous alcohol, isopropyl alcohol, acetone and so on.Remove rust, dust, oil and water.
- Cut the nozzle with a paper cutter, squeeze the adhesive onto the cleaned surface, make it evenly distributed, and close the sticky surface and fix it within the surface drying time.Put the coated parts in the air and let them cure at room temperature for 24 hours before putting them into use.
- After the operation is completed, the unused adhesive should be tightened the cap immediately, sealed and stored. When using again, if there is a little crust at the sealing place, it can be removed without affecting the normal use.
Features of MS Hybrid Sealant
1. Safe and pollution-free
MS Hybrid Sealant is designed with 100% solid components, no solvents, no formaldehyde, no benzene release, VOC content is less than 10g/L, and has passed the EU REACH certification and the German GEV EC1 Plus environmental protection grade certification. It can effectively reduce the risk of indoor air pollution and ensure the health and safety of construction workers and end users.
2. No need for bonding treatment
The product has excellent bonding to more than 30 substrates such as metal (aluminum, steel), glass, concrete, plastic (PVC, ABS), wood, etc., with a bonding strength of 2.8-4.1MPa (ASTM D903 standard), and no primer treatment is required, and no polishing or cleaning of the substrate surface is required, which improves construction efficiency by 40%.
3. Weather resistance and elastic recovery
After 7 days of artificial weather aging test (ISO 9142 standard), the product’s tensile strength retention rate exceeded 90%, light transmittance > 89%, and elastic recovery rate reached 91% (ASTM D3107 standard), which can adapt to ±25% joint deformation (JG/T 475-2015 standard). In extremely cold (-40℃) and high temperature (90℃) environments, it can still maintain flexibility and avoid cracking or falling off, and is suitable for extreme environmental scenarios such as rail transit and wind power equipment.
4. Paintability and color customization
After curing, the surface can be painted with water-based paint or oil-based paint, and supports Pantone color card customization to meet the color consistency requirements of building curtain walls and interior decoration. For example, in high-end commercial complex projects, gray or beige sealants can be customized to form a seamless visual effect with stone curtain walls and enhance the overall aesthetics.
5. Adapt to humid environments
The single-component design does not require mixing, and the surface drying time is only 25-30 minutes (23℃/50%RH conditions), and it can be constructed in an environment with humidity > 30%, solving the problem of traditional polyurethane glue bubbling on humid substrates.
Application scenarios of MS Hybrid Sealant
1. Sealing joints in prefabricated buildings
It is used for sealing joints in precast concrete wall panels, floor slabs, balconies, etc. Its low modulus (0.3-0.5MPa) characteristics can absorb the stress caused by building settlement and avoid cracking and leakage.
2. Automobile manufacturing and maintenance
Applied to body sheet metal bonding, windshield sealing, lamp assembly and other links, withstanding temperature fluctuations from -40℃ to 120℃, and passed EN 45545-2 fireproof certification (railway transportation carriage sealing with the same standard).
3. Electronic and electrical packaging
Used for fixing and sealing components such as LED display screens, circuit boards, sensors, etc., with a dielectric strength of 15kV/mm (IEC 60243-1 standard), which can effectively prevent short circuit failures caused by moisture intrusion. In the construction of 5G base stations, the weather resistance and insulation of MS glue can extend the service life of the equipment to more than 10 years.
4. Door, window and curtain wall sealing
Replacing traditional silicone glue for peripheral sealing of aluminum alloy doors and windows and glass curtain walls, its pollution resistance (no silicone oil precipitation) can avoid the problem of blackening of the surface after long-term use, and the paintability supports the same color treatment as the exterior wall of the building, improving the overall aesthetics.
5. Industrial equipment bonding
It is used for sealing and bonding of wind turbine blades, ship decks, mechanical equipment and other scenes. Its UV resistance (QUV accelerated aging for 3000h without powdering) can ensure the long-term stable operation of outdoor equipment.
Cleaning and maintenance of MS Hybrid Sealant
1. Cleaning before construction
Wipe the surface of the substrate with isopropyl alcohol or anhydrous ethanol to remove impurities such as oil, dust, etc., and ensure that the bonding surface is dry and clean. For metal substrates, sandpaper should be used to polish to St3 level (ISO 8501-1 standard) to enhance the bonding strength.
2. Maintenance after curing
Before curing, acetone or special cleaning agent can be used to remove excess colloid; after curing, it needs to be removed by mechanical methods (such as blades) to avoid damaging the substrate. Check the sealing parts regularly. If cracks or detachment are found, the glue should be replenished in time and the old glue residue should be cleaned.
3. Storage conditions
The product should be stored in a dry, ventilated and cool place (temperature ≤27℃), avoiding direct sunlight or high temperature environment. The shelf life of unopened products is 12 months. After opening, they must be used up within 1 month and kept sealed to prevent moisture from entering and causing premature curing.
