  • Customized decontamination formulas: Targeting stain characteristics of different industries (e.g., PU\/EVA adhesive residues in the footwear industry, grease and coating residues in the leather industry, and micro-impurities in high-speed rail accessories), we develop specialized aqueous solvents. The core composition includes 20% active agents + 10% auxiliaries + 70% water, combining strong decontamination with gentle protection to avoid damaging substrates.<\/h6><\/li>
  • Environmental and safety guarantees: The water-based solvents fully comply with EU REACH and ISO 14001 standards, featuring ultra-low VOC emissions and significantly reduced hazardous waste generation, eliminating environmental and safety risks at the source.<\/h6><\/li>
  • Stable and durable design: With a service life of up to 7 days after preparation, the solvents adapt to temperature and pressure requirements of different cleaning scenarios, maintaining consistent decontamination performance and reducing replacement frequency.<\/h6><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
