Features
Non-Corrosive Neutral Curing System
Releases neutral byproducts during curing, free of acidic or alkaline substances. Safe for contact with sensitive substrates like copper, zinc, stainless steel, natural stone (marble, granite) and decorative surfaces, without causing discoloration, rust or material degradation.
Excellent Multi-Substrate Adhesion
Forms strong, long-lasting bonds with porous materials (concrete, masonry, wood) and non-porous materials (glass, PVC, acrylic) without the need for primers. Eliminates the hassle of substrate-specific sealant selection for mixed-material projects.
Superior Weather & UV Resistance
Withstands extreme temperatures ranging from -50℃ to 180℃, as well as prolonged UV exposure, rain, wind and ozone. Maintains flexibility and sealing integrity for over 15 years outdoors, resisting cracking, hardening and brittleness.
High Elasticity & Displacement Compensation
Boasts an elongation rate of ≥300% and can accommodate ±25% substrate movement caused by thermal expansion, contraction or structural vibration. Effectively prevents leakage in dynamic joints such as curtain walls and pipeline connections.
Application
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 skyscrapers, commercial complexes and luxury residential buildings. Its non-corrosive formula protects high-value sensitive substrates from discoloration or damage, while excellent weather resistance ensures long-term airtightness and waterproofing.
Door & Window Installation & Sealing
Widely applied to seal frame-sash gaps, glass-to-profile bonding seams and wall openings around broken-bridge aluminum, PVC and solid wood doors/windows. It adapts to thermal expansion, contraction and vibration from daily use, effectively blocking air infiltration, rainwater leakage and noise transmission to enhance building energy efficiency.
Kitchen & Bathroom Waterproof Sealing
Perfect for sealing gaps between kitchen countertops and walls, sink-countertop joints, shower enclosures and tiles, as well as toilet bases. Features strong waterproof and mold-resistant performance, with low odor and low VOC emissions, making it safe for indoor use in residential homes, hotels and hospitals.
Electronic & Electrical Equipment Protection
Used for waterproof and dustproof sealing of LED lamp housings, power adapters, control panels and photovoltaic (PV) module frames/junction boxes. Resists extreme temperatures (-50℃ to 180℃) and aging, without corroding metal contacts or plastic casings, ensuring stable operation of electronic components in harsh environments.
