Process Logic & Key Control Points
Synergistic Process Logic of Haoqian HQ Additives
Multi-functional empowerment of HQ-3295: Add 1 part HQ-3295 during dispersion stage. Its amphiphilic molecular structure effectively stabilizes emulsion interface, simultaneously adjusting system pH to the optimal range of 8.0-9.0 to prevent uneven gloss caused by pH fluctuation.
Full-cycle anti-mold protection by HQ-2025: Addition of 2 parts HQ-2025 covers anti-mold demands throughout production, storage and construction. Especially for high-polymer-content topcoats, it efficiently restrains mold proliferation and enzymatic hydrolysis reactions.
Synergistic optimization with coalescent agents: This formula adopts composite film-forming system composed of Haoqian HQ-6737 and ethylene glycol. The presence of HQ-3295 greatly improves dispersion efficiency of coalescent agents in emulsion, lifting low-temperature film-forming performance by around 20%.
Key Process Control Points
Precise viscosity regulation: Gradually add original HQ-6103 thickener (final dosage 15.6 parts), combined with rheology auxiliary function of HQ-3295, to stabilize viscosity at 65.7 KU and balance leveling and anti-sagging performance during construction.
Optimized feeding sequence: Recommended feeding order: "Water → HQ-3295 → HQ-2025 → Coalescent Agent → Emulsion → Thickener", to avoid defoamer failure from high-speed shearing.
Summary of Haoqian Technical Solution Values
Wide compatibility: HQ-3295 delivers outstanding compatibility with mainstream emulsions including Haoqian HQ-9530, Satellite and Baolijia, enabling quick formula adjustment.
Consistent quality: Combined usage of HQ-2025 and HQ-3295 extends the service life of opened topcoat products to more than 6 months.
Simplified production process: Synergistic effect of HQ-6103 thickener and HQ-3295 eliminates complicated separate feeding steps required for traditional thickeners.
