FluoroSyl 4500 is a perfluoropolyether silane with good durability, lubricity and abrasion resistance. On glass the coating provides good anti-reflective and oleophobic properties. FluoroSyl is recommended for glass and metal surfaces for fingerprint resistance, stain repellency and easy cleaning. FluoroSyl on mesh and filters forms an excellent anti-fouling and anti-fingerprint agent.
Quantity: 10 grams Application methods: PVD (or dilute to 0.2% with IPA and spritz and squeegee or dip) Curing: Air dry for 24 hours (or bake 100°C for 10 minutes with 50% relative humidity) Transparent: Yes Refractive Index: 1.3 Density: 1.55 g/ml Static Contact Angle to Water (2 µl): >95° Static Contact Angle to Mineral Oil (20 µl): >50° Contact Angle after 5,000 Cotton Rubs @ 2.5 g/sq-mm: >90°
Clean glass and metal with plasma or corona first prior to application of FluoroSyl. Apply FluoroSyl immediately after surface preparation by PVD. Allow the FluoroSyl to dry for 2 hours or more. Using a soft cloth wipe off any haze or cloudiness. The glass or metal should now repel water, oil, paint, ice and other materials. After cleaning and diluting to 0.2% with IPA, FluoroSyl can also be applied by dipping and spraying.
