Advantages
Non-Corrosive & Material-Safe Formula
Releases neutral byproducts (no acidic/alkaline substances) during curing, safely compatible with sensitive metals (copper, zinc, aluminum), natural stone (marble, granite), glass, and decorative surfaces. Prevents discoloration, corrosion, or material degradation—ideal for high-value substrate sealing in luxury projects.
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 (e.g., curtain walls, mixed-material decorations).
Superior Weather & Aging Resistance
Withstands extreme temperatures (-50℃ to 180℃) and resists UV radiation, ozone, heavy rain, and humidity. Maintains long-term flexibility (elongation rate ≥ 300%) without cracking, hardening, or brittleness, ensuring reliable sealing performance for 15+ years in outdoor and high-exposure environments.
Strong Elasticity & Displacement Compensation
Adapts to ±25% substrate movement caused by thermal expansion, contraction, or structural vibration. Features shear strength ≥ 1.0 Mpa and tensile strength ≥ 1.2 Mpa, effectively preventing leakage in dynamic joints (e.g., pipeline connections, curtain wall gaps).
Application Scenarios
High-End Building Curtain Walls & Facades
Ideal for sealing joints between glass panels, aluminum alloy frames, natural stone cladding (marble, granite), and aluminum composite panels in commercial complexes, skyscrapers, and luxury residential buildings. Its non-corrosive formula protects sensitive metals and high-value stone surfaces, while superior weather resistance (withstands -50℃ to 180℃, UV radiation, and heavy rain) ensures long-term airtightness, waterproofing, and structural stability—meeting the strict requirements of high-end construction projects.
2. Door & Window System Installation
Widely used for sealing frame-sash gaps, glass-to-profile bonding seams, and wall openings around broken-bridge aluminum, PVC, and solid wood doors/windows. Compatible with multiple door/window materials and hardware (no corrosion), it exhibits excellent elasticity to adapt to thermal expansion, contraction, and vibration from opening/closing. Effectively blocks air infiltration, rainwater leakage, and noise transmission, enhancing energy efficiency and comfort of buildings.
3. Roofing & Plumbing Waterproof Sealing
Applied to key waterproof nodes such as roof parapets, drain outlets, and pipe penetrations; also suitable for sealing gaps between kitchen countertops and walls, sink-countertop joints, shower glass and tiles, and toilet bases. Features outstanding waterproof and moisture-proof performance, preventing mold growth. Low odor and low VOC emissions comply with indoor environmental standards, making it safe for residential, hotel, hospital, and nursery school applications.
4. Electronic & Electrical Equipment Sealing
Used for waterproof, dustproof, and moisture-proof sealing of LED lamp housings, power adapters, control panels, and photovoltaic (PV) module frames/junction boxes. Resists extreme temperatures and aging, protecting electronic components from humidity and dust erosion without corroding metal contacts or plastic casings—ensuring long-term stable operation of equipment in harsh environments.
