RepelFlex HC is designed to provide a hard scratch resistant coating to plastic surfaces while providing protection against microbial growth and dirt and stains. Ideal applications include:
- Mobile device cases and accessories
- Laptop and tablet cases
- Wearable electronics
- Personal Protective Equipment (face shields, goggles, protective barriers and films)
- Other consumer and industrial applications where scratch and abrasion resistance are critical
Wet based deposition methods such as dip or wipe are acceptable. Atomized spray preferred. UV curing is achieved at 1,100 to 1300 mJ/cm² using a standard class "H" lamp. For some applications a short bake at 50-70°C is recommended prior to the UV cure step.

Technical Details & Test Data
- Technology
The unique characteristics of RepelFlex HC result from a combination of proprietary polymers with distinct phases and properties. Optimizing the ration and concentration of these polymers and additives is the key to enabling outstanding adhesion to most plastics and delivering the critical performance parameters; optical clarity, abrasion resistance, and the protection against microbials and stains. RepelFlex HC can be applied using simple atomized spray equipment followed by a rapid cure through the exposure to UV light and is formulated to be solvent and fluorine-free.
