Challenge: Wetting Failure on Metal
Residual oil/oxide layers cause interfacial tension mismatch. Traditional wetting agents induce microfoaming during spraying.
Innovation: Silicone-Phosphate Hybrid
Gradient Penetration: Siloxane spreads rapidly while phosphate anchors micro-pores;
Anti-foaming Synergy: Polyether blocks suppress foam;
Electrolyte Resistance: Stable in 5% NaCl >240 hours.
Case: Storage Tank Adhesion Improvement
For epoxy-coated steel tanks:
Adhesion increased from 3.5 MPa to 8.2 MPa;
Salt spray corrosion width at scratches reduced by 75%.
