In the automotive parts, home appliance casing, and construction machinery industries, traditional phosphating processes suffer from environmental problems such as phosphorus-containing wastewater discharge, high energy consumption, and complex processes. Anhui Aiyota's silane coupling agent metal pretreatment technology, with its advantages of environmental friendliness, energy saving, and high efficiency, is becoming a mainstream alternative to phosphating.

This silane pretreatment agent contains multiple hydrolyzable alkoxysilane groups and functional groups (such as amino, epoxy, and mercapto groups) that can coordinate with the metal surface, forming a 100-500 nm thick organic-inorganic hybrid film on the metal surface. This provides excellent corrosion resistance and enhances the adhesion of subsequent coatings. Salt spray tests show that the electrophoretic coating after silane treatment achieves a salt spray resistance time of 800-1200 hours, comparable to phosphating, but with a 50% shorter process flow, 40% lower energy consumption, and no phosphorus or chromium wastewater discharge.

Aiyota offers a variety of silane systems for metal processing, including zirconium-silicon composite, titanium-silicon composite, and pure silane, suitable for various substrates such as aluminum alloys, galvanized sheets, cold-rolled sheets, and magnesium alloys. The products are already widely used in industries such as home appliances, automobiles, and building materials, and have passed international standard certifications such as VDA233-102 and GMW14872. The technical service team can provide production line transformation solutions, process parameter optimization, and on-site commissioning support to help companies achieve green manufacturing upgrades.
