Product highlights

CoreAdvantages

Lotus-effect micro/nano hierarchical structure

Nano SiO2/TiO2 particles build a micro-scale protrusion (2-5μm) + nano fuzz (50-200nm) hierarchical rough structure. Water droplets are in the Cassie-Baxter state (trapped air layer) with a contact angle >150° and roll off in spherical form. Rainwater naturally washes away surface dust to achieve cleaning-free self-cleaning.

Transparent, colorless, no impact on the substrate

Dry film thickness<500nm在可见光RangeTransparent无色。Glasstransmittance impact<1%。对Stone/Metal/Plastic原有Colortexture无改变。Suitable ForArchitectural幕墙和历史ArchitecturalProtection等美学Requirements高的Application Scenarios。

Outdoor durability with 5-year long-term protection

Organic-inorganic hybrid siloxane (ORMOSIL) firmly anchors nanoparticles to the substrate surface. After 2000h xenon lamp aging, the contact angle remains >140°. Resistant to simulated rainstorm washing for 1000h with no degradation. Coating damage can be easily repaired by re-coating to restore the superhydrophobic function.

Professional coating technology support services

Kexin boasts an experienced coatings R&D and application technology team, providing comprehensive services from substrate analysis, coating selection, and process parameter optimization to on-site application guidance. We work in conjunction with our clients' coating production lines to fine-tune coating application parameters, ensuring optimal coating quality and production efficiency.

Eco-compliant green manufacturing system

All products are RoHS/REACH certified and meet national environmental standards for VOC content. Water-based and high-solids, low-VOC formulations are continuously iterated to meet increasingly stringent environmental protection requirements. Environmental performance test reports from authoritative third-party testing institutions such as SGS and CTI are provided.

Complete quality control and batch traceability

A comprehensive quality control system is in place from raw material intake to finished product delivery. Each batch of products undergoes rigorous physical and chemical performance testing and coating simulation testing. Batch numbers are fully traceable, allowing for tracking of raw material origins and production process data. Each product comes with a batch test report and product warranty certificate for customer peace of mind.

Application guide

ApplicationProcess

Substrate cleaning

Thoroughly clean the substrate surface with anhydrous ethanol to remove oil and dust. Optical glass requires plasma treatment for further surface activation. Plastic substrates may optionally undergo flame or plasma pretreatment. Ensure the substrate surface is absolutely clean with no residue.

Primer / adhesion promotion

Apply nano adhesion-promoting primer or silane coupling agent according to substrate type. Enhance interfacial bonding between the nano coating and substrate through chemical bonding. PVD process requires no primer and is completed directly in the vacuum chamber. Primer dries for 5-10min.

Nano coating application

Use spray coating/dip coating/spin coating/wipe coating/PVD and other processes according to coating type. Anti-fingerprint oil by PVD evaporation or spray coating + high-temperature curing. Self-cleaning coating cures at room temperature after spray coating. ITO coating deposited by magnetron sputtering. Precisely control film thickness at 5-500nm.

Curing and post-treatment

Thermal curing (80-150°C/15-60min) or UV curing (800-1200mJ/cm²) as required by the coating. Some coatings require constant temperature and humidity conditions to ensure uniform film formation. After curing, naturally cool to room temperature for performance testing.

Performance testing

Test key indicators such as contact angle/light transmittance/haze/adhesion/abrasion resistance/sheet resistance. After all performance criteria are met, package with dust-free materials for shipment. Batch test reports and warranty certificates are included.
