Quality Control Process
Step 01
Raw Material Inspection
All incoming raw materials for adhesives (including monomers, polymers, curing agents, fillers, and additives) undergo rigorous testing to ensure they meet our strict specifications before entering
- ✓Chemical purity analysis (e.g., monomer purity ≥99.5%, impurity content ≤0.1%)
- ✓Compatibility testing with other formula components
- ✓Supplier qualification and certification verification (e.g., REACH, RoHS compliance)

Step 02
In-Process Quality Checks
Automated and manual inspections are performed at critical stages of adhesive production (mixing, dispersion, curing parameter control), ensuring that each manufacturing step meets our exacting standards.
- ✓Real-time monitoring of mixing speed, temperature, and time (e.g., error range ≤±2℃ for mixing temperature)
- ✓Viscosity and solid content testing of intermediate adhesive products (e.g., viscosity deviation ≤±5% of standard value)
- ✓Homogeneity inspection of adhesive mixture (no visible agglomerates, particle size ≤5μm for fillers)

Step 03
Finished Product Testing
Every finished adhesive product undergoes comprehensive testing to verify bonding strength, curing speed, environmental resistance, and safety performance before packaging.
- ✓Bonding strength testing (e.g., shear strength ≥15MPa for structural adhesives, peel strength ≥5N/mm for flexible adhesives)
- ✓Curing performance verification (e.g., full curing time ≤24h at room temperature, or ≤30min under UV irradiation)
- ✓Environmental resistance tests (high-temperature resistance: -40℃~120℃ for 1000h without performance degradation; water resistance: immersion in 25℃ distilled water for 500h, bonding strength retention ≥80%)

Step 04
Packaging and Shipping Inspection
Final inspections ensure that products are properly packaged and labeled, with all necessary documentation, to prevent damage during transportation.
- ✓Packaging integrity verification
- ✓Label accuracy confirmation
- ✓Documentation completeness check
