FAQ
Q1: What is the difference between 3789 and 3789L?
A: 3789L is a lower viscosity grade (7500±1000 mPa·s) with faster curing at 600 mJ/cm², while 3789 offers higher viscosity (11500±2000 mPa·s) and cures at 800 mJ/cm². Both provide excellent adhesion to glass and metal.
Q2: What surfaces can this adhesive bond?
A: It is specially designed for galvanized sheets, LCD metal backplates, glass panels and other metal surfaces, delivering excellent adhesion and corrosion resistance.
Q3: Is the adhesive resistant to alkali and corrosion?
A: Yes. The formulation provides outstanding alkali resistance and corrosion resistance, ensuring stable long-term performance in demanding environments.
Q4: What are the storage requirements and shelf life?
A: Shelf life is 12 months when stored at 8-28°C in a cool, dry place away from direct sunlight. Keep the container tightly sealed after use.
Q5: What packaging options are available?
A: Standard packaging is 250 ml and 1 kg. Custom packaging such as syringes, bottles and other sizes can be provided upon request for OEM orders.
