HW-719 low temperature resistant structural sealant for aquariums/curtain walls EN 13022-2 certified 300ml aluminum tube
Core performance parameters
1. Breakthrough bonding strength
Glass/aluminum substrate interface bonding strength ≥1.8MPa, reaching the highest grade standard of building structural adhesive (300% higher than national standard), passed 10,000 times ±12.5% dynamic displacement test
2. Extreme climate stability
Maintains stable elastic modulus in the full temperature range of -50ºC to 200ºC, 5,000 hours of QUV accelerated aging without cracking or discoloration, passed the CTC extreme climate simulation test of China Academy of Building Materials Science
3. Engineering-grade curing system
Achieve 20 minutes of surface drying and 24 hours of complete curing (3mm adhesive layer) under a standard environment of 25ºC, which is 30% faster than traditional neutral curing adhesives, supporting rush projects in rainy season
Key scenario solutions
Ultra-large curtain wall projects
Designed for single-piece glass over 5M2, verified by ANSYS 18.0 wind pressure simulation, can withstand 150km/h typhoon-level shear force
High-corrosion environment protection
After 3000 hours of salt spray test, the bonding strength retention rate is >95%, which has been applied to the glass curtain wall system of the artificial island of the Hong Kong-Zhuhai-Macao Bridge
Precision assembly control
0.1mm-level glue joint precision control technology solves the problem of micro-gap leakage between curved glass and special-shaped metal frames
Permanent transparency commitment
Nano-level cross-linking technology ensures 20-year yellowing index ΔE <1.5 (ASTM D2244), and has been certified as a global supplier of glass display cabinets at the LV flagship store
Material Adaptation Specifications
[V] Applicable Substrate Group
• Glass/ceramic: requires isopropyl alcohol wiping + 120-grit sandpaper roughening
• Anodized aluminum: used with MX-12 special primer
• 304/316 stainless steel: surface roughness must reach Ra6.3μm or above
[x] Disabled scene warning
• Porous substrate (when the moisture content of concrete/wood is greater than 12%, the risk of peeling increases by 47%)
• Electrochemically active metals (copper/zinc contact surfaces need to be insulated and isolated)
• Fully submerged hydraulic structure (it is recommended to use a two-component epoxy sealing system instead)
Technology gap between competitors
• VS ordinary neutral glue: curing speed increased by 30% → single project saves 5-7 days
• VS cheap acrylic glue: service life extended from 3 years to 25 years (ASTM C794 accelerated aging verification)
• VS general architectural glue: improve glass installation accuracy from ±1.5mm to ±0.1mm
We use raw materials supplied by the world's leading chemical giants,
Chemical material inventory of thousands of tons or more.Have more production capacity than peers.
The production process of the adhesives is completely enclosed to prevent external temperatures and various uncontrollable factors from affecting the quality of the product.
