Neutral silicone sealant

Neutral Silicone Weatherproof Sealant is a high-performance silicone-based sealant with the following product characteristics and main applications:

Product Characteristics:

1. Neutral Curing:

• Non-corrosive to substrates, suitable for various materials (e.g., glass, metal, stone, ceramic, plastic), and does not cause metal oxidation or concrete carbonation

2. Excellent Weather Resistance:

• Resistant to UV rays, extreme temperatures (-40°C to 150°C), ozone, and aging. Remains crack-free and color-stable under long-term outdoor exposure

3. Strong Adhesion:

• Bonds effectively with most construction materials without the need for primers

4. Flexibility and Seismic Performance:

• High movement capability (up to ±25% to ±50%), accommodating dynamic joint displacements and resisting vibrations and cracks

5. Waterproof and Moisture-Resistant:

• Low water permeability, effectively preventing rainwater infiltration. Ideal for damp environments

6. Eco-Friendly and Non-Toxic:

• Solvent-free, low odor, and compliant with environmental standards (some products are RoHS or SGS certified)

7. Color Variety:

• Available in transparent, white, black, and other colors to match diverse decorative needs

Main Applications:

1. Building Curtain Wall Sealing:

• Sealing joints in glass, aluminum panel, stone curtain walls, ensuring waterproofing and structural durability

2. Door and Window Installation & Gap Filling:

• Sealing gaps between frames and walls to improve air and water tightness

3. Roof and Exterior Wall Waterproofing:

• Sealing roof joints, exterior wall expansion joints, and decorative moldings against leakage

4. Interior Decoration:

• Waterproof sealing in wet areas such as tiles, bathrooms, and kitchen countertops

5. Industrial Applications:

• Bonding and sealing industrial components in automotive, shipbuilding, solar panels, and ventilation ducts

6. Maintenance and Repair:

• Repairing cracks or leaks in aging building structures

Important Notes:

• Surfaces must be clean, dry, and free of oil or contaminants before application

• Curing time depends on temperature and humidity (typically surface-dry in 30–60 minutes, fully cured in 24–72 hours)

• Avoid prolonged immersion in water or exposure to temperatures exceeding 150°C

Neutral Silicone Weatherproof Sealant is widely used in construction, household, and industrial sectors due to its versatility and durability, making it an ideal choice for outdoor sealing projects
