2. Classification by Application
High-strength structural bonding
Epoxy modified adhesive (such as Kanglibang adhesive).
Acrylic structural adhesive (passed rigorous automotive industry testing).
Requirement: Withstand shear, tensile, or peel forces.
Recommended product: Kanglibang adhesive
Flexible impact-resistant adhesive
Polyurethane adhesive (KL17 modified version, impact strength 12J/m²).
High-temperature resistant soft adhesive (98% press line position retention rate).
Requirement: Absorb vibration energy and prevent brittle fracture.
Recommended product: Kanglibang liquid hot melt adhesive
Extremely fast-curing adhesive
Metal-specific instant adhesive (initial cure in 5 seconds).
UV-curing adhesive (full cure in 1.2 seconds, suitable for precision instruments).
Requirement: Reduce production cycle time and improve efficiency.
Recommended product: Kanglibang instant adhesive
Special material compatibility
Silicone metal adhesive.
Carbide adhesive (laser welding yield increased by 42%).
Requirement: Solve the problem of bonding dissimilar materials. Recommended Product: Kanglibang Adhesive
3. Key Selection Criteria
Material Compatibility:
Metal surfaces require degreasing and rust removal (e.g., wiping with trichloroethylene solvent or degreasing with alkaline solution).
Nanofillers can optimize thermal expansion coefficient matching (e.g., reducing the debonding rate of wind turbine equipment by 89%).
Environmental Tolerance:
Heat and humidity resistance: Fluorinated modified adhesives pass a 2000-hour salt spray test.
High-temperature resistance: Inorganic silicate adhesives retain 87% of their strength after thermal shock at 1350°C.
Process Compatibility:
Coating Speed: Roller-coated adhesives achieve efficient production at 4.2 m/min.
Dispensing Accuracy: UV adhesives combined with 3D molds achieve 0.3 mm accuracy.
