Hw-719 Aquarium Structural Glue High Strength Waterproof Adhesive for Large Fish Tanks, UV Resistant Glass Sealant

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
