ProductsOverview
Superhydrophobic self-cleaning coating is a high-performance professional coating product developed and produced by KeXin New Material. It is scientifically formulated with high-quality resins and imported pigments and fillers, offering excellent adhesion, durability, and application performance. It is widely used in industrial manufacturing, architectural decoration, automotive transportation, and other fields.
As a source coating factory, KeXin New Material strictly implements the ISO9001 quality management system for Superhydrophobic self-cleaning coating from formula design and raw material procurement to production and filling. The product has passed ROHS, REACH, and other environmental regulation certifications. Free sample testing and on-site guidance by technical engineers are provided.
Why choose a superhydrophobic self-cleaning coating?
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 and colorless。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 has an experienced coatings R&D and applications team that supports the whole process - substrate analysis, coating selection, optimisation of process parameters and on-site application guidance. Our engineers commission the coating parameters on your own production line so that finish quality and output are both optimised.
Eco-compliant green manufacturing system
All products are RoHS/REACH compliant and their VOC content meets national environmental standards. Waterborne and high-solids low-VOC formulations are continuously refined to keep pace with ever stricter environmental requirements. Environmental performance test reports issued by third-party authorities such as SGS and CTI are available on request.
Complete quality control and batch traceability
A quality-control system covering the whole process, from incoming raw materials to finished-goods dispatch. Every batch undergoes rigorous physico-chemical testing and simulated application trials. Batch numbers are traceable end to end, so raw-material sources and production data can be retrieved. Each shipment is released with a batch test report and a product warranty, so customers can use it with confidence.

Frequently AskedFAQ
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.
