Weather Resistance Black Neutral Silicone Sealant Glass Window

Advantages

1. Non-corrosive & Material-Safe Formula:Releases neutral byproducts during curing, free of acidic/alkaline substances. Safely compatible with sensitive metals (copper, zinc, aluminum), natural stone, glass, and decorative surfaces—prevents discoloration, corrosion, or material degradation, ideal for high-value material sealing.
2. Exceptional Substrate Versatility:Bonds firmly to both porous (concrete, masonry, wood) and non-porous (PVC, acrylic, stainless steel) materials without primers. Eliminates the need for substrate-specific sealants, simplifying procurement and construction for multi-material projects.
3. Superior Weather & Aging Resistance:Withstands extreme temperatures (-50℃ to 180℃), UV radiation, heavy rain, and ozone. Maintains long-term flexibility (elongation rate up to 300%) without cracking, hardening, or brittleness—ensures reliable sealing performance for 15+ years outdoors.
4. Strong Elasticity & Displacement Compensation:Adapts to ±25% substrate movement caused by thermal expansion, contraction, or structural vibration. Effectively prevents leakage in dynamic environments (e.g., curtain walls, pipeline joints) with shear strength ≥1.0 Mpa and tensile strength ≥1.2 Mpa.

Application

1. High-End Building Curtain Walls & Facades:Seals gaps between glass panels, aluminum alloy frames, and natural stone cladding in commercial skyscrapers, luxury residential buildings, and public facilities. Its non-corrosive formula protects sensitive metals (copper, zinc) and stone surfaces, while superior weather resistance withstands wind, rain, and UV radiation for long-term structural sealing.
2. Indoor Sanitary & Decoration Areas:Ideal for kitchen (backsplash edges, sink-countertop joints, stove gaps) and bathroom (shower glass seams, toilet bases, faucet connections) sealing. Low odor, low VOC, and mold-resistant properties make it suitable for high-humidity, enclosed spaces like bedrooms, hospitals, and baby rooms—safe for daily contact environments.
3. Industrial Equipment & Electronic Enclosures:Used for waterproof, dustproof, and vibration-resistant sealing of automotive lamp assemblies, photovoltaic (PV) module frames, electronic device casings, and HVAC system ducts. Withstands extreme temperatures (-50℃ to 180℃) and chemical exposure, ensuring equipment reliability in harsh working conditions.
4. Commercial Spaces & Public Infrastructures:Seals shopping mall display cabinets, hotel bathroom fittings, airport terminal glass partitions, and subway station wall joints. Balances aesthetic finish, durability, and environmental compliance, meeting the high standards of high-traffic commercial and public projects.
5. High-Value Material Sealing:Compatible with natural stone (marble, granite, travertine), decorative metals, and plastic substrates. Perfect for sealing luxury furniture edges, custom glass art, and high-end decorative surfaces—prevents material discoloration or corrosion while maintaining a neat appearance.
6. DIY Home Renovation & Furniture Installation:Suitable for window/door frame gaps, mirror back edges, wooden furniture joints, and aquarium glass sealing. Easy application with a caulking gun, strong adhesion to multi-materials, and paintable surface (for aesthetic customization) meet the needs of amateur users and professional installers alike.
