RepelFlex-L is designed to provide outstanding anti-scratch and anti-stain protection to genuine and faux leather surfaces. Ideal applications include the following:
- Luxury leather goods and accessories (handbags, belts, bracelets, wallets, watch bands, etc.)
- Footwear
- Seating (automotive, aerospace, home and office furniture, etc.)
- Other applications where the protection against scratching and stains is equally important as the retention of the look and feel of genuine leather
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-L result from a combination of proprietary polymers with distinct phases and properties. Balancing the ratio of these polymers is the key to enabling the unique characteristics of hardness, durability, and flexibility. RepelFlex-L is designed to be applied using simple atomized spray equipment followed by a rapid cure through the exposure to UV light. RepelFlex-L is formulated to be solvent and fluorine-free.
