- The Duravance® series developed by Rayoung Chemtech over several years is composed of various synthetic reaction materials such as polysilazane, polysiloxane, silicone resin, fluorine monomer, acrylic, etc., and is designed according to the actual application requirements. They are all polymers in structure and can be used as the main resin or as an additive depending on the situation. Ensure compliance with RoHS & REACH SVHC, PFOA, PFOS and other prohibited substance specifications.
- High compatibility of silane-based coatings and related formulations. With organic/inorganic polysilazane resins, polysiloxane resins, general silicone resins, UV-curable resins, etc., modules can be designed to strengthen different target functions.
- High hydrophobicity, high oleophobicity: fingerprint non-stick, high water contact angle 110~125∘, low water sliding angle 7~20∘, oil-resistant strange pen, anti-graffiti, mold (vacuum breaking) release, etc.
- Gloss change: glossy, satiny, and matte finish, still transparent.
- Corrosion resistance: Change the crystalline state and form a dense fluoride layer surface, which can resist both acid and alkali.
- Salt spray resistance. (ASTM B117-18 >4000 hours)
- High weather resistance (no change in appearance, no chalking, no gloss change! )
- Cyclic corrosion resistance.
- Both hardness (scratch resistance, the minimum will be greater than 2~4H), and toughness (T-Bend Test: 0T)
- Hard Impact Resistance.
- Thermal shock resistance.
- Increase hand slippery feel.
- High or low film thickness. (0.5~20um)
- Conductive、 insulating. (with specified/other additives)
- Heat conduction, heat insulation. (requires specified/other additives)
- Long-lasting antibacterial and antiviral. (with other additives)
- Coloring thin coating. (requires specified color paste)
- Moisture curing, heat curing, UV curing.
