Modified Silane StrSealant

MS Sealant (Modified Silane Polyether Sealant)

MS Sealant (Modified Silane Polyether Sealant) is a high-performance sealant that combines the advantages of polyurethane and silicone sealants, offering excellent weather resistance and application properties

I. Properties of MS Sealant

1. Environmentally Friendly & Non-Toxic: Solvent-free and isocyanate-free, with low VOC emissions, complying with environmental standards

2. Excellent Weather Resistance: Resistant to UV rays, high and low temperatures (-40°C to 100℃), does not yellow or crack during long-term outdoor use

3. Versatile Adhesion: Bonds well to various substrates including concrete, metal, glass, and plastics

4. Durable Elasticity: Maintains high elasticity after curing, accommodating the thermal expansion and contraction of substrates

5. Paintability: The surface can be painted, a characteristic not typically found in standard silicone sealants

6. Non-Corrosive: Does not corrode metal or concrete substrates

II. Main Applications of MS Sealant

1. Construction Field: Sealing curtain wall joints, door/window installation, concrete joint treatment, roof waterproofing, etc

2. Industrial Manufacturing: Seam sealing and bonding in automobiles, ships, and containers

3. Decoration & Finishing: Bonding and sealing interior/exterior decorative materials, such as stone and aluminum panels

4. Municipal Engineering: Expansion joint treatment in concrete structures like bridges and tunnels

5. Home Repair & Renovation: Waterproof sealing in damp environments like bathrooms and kitchens

III. Curing Time of MS Sealant

MS sealant cures by reacting with moisture in the air. Under standard conditions (temperature 23±2°C, relative humidity 50±5%):

• Surface Dry Time: Approximately 30-60 minutes (forms a skin)

• Initial Cure: Reaches about 70% strength within 24 hours

• Full Cure: Typically requires around 7 days to achieve final properties

Curing speed is significantly affected by ambient temperature and humidity:

• High temperature and high humidity can accelerate curing

• Low temperature and low humidity will slow down curing

• Thicker application layers require longer full cure times

IV. Usage Precautions

1. Pre-Application Preparation:

• Ensure the application surface is clean, dry, and free of oil, grease, and loose particles

• A primer is recommended for porous substrates

• Recommended application temperature is between 5°C and 40°C

2. Application Guidelines:

• Cut the nozzle to an appropriate size to ensure the bead meets design requirements

• Use proper application technique to ensure full contact between the sealant and the substrate

• Control joint depth; use backer rod if necessary

• Tooling must be completed before surface skin forms

3. Safety Measures:

• Avoid direct skin contact; wearing protective gloves is recommended

• If skin contact occurs, wash immediately with soap and water

• Maintain good ventilation in the work area

• Store out of reach of children

4. Storage Requirements:

• Store unopened products in a cool, dry place

• Recommended storage temperature is between 5°C and 30°C

• Use opened cartridges promptly or seal them with a specialized cap
