2. Product description
The Polyurethane slurry can curdle quickly when we paint the surface of sandwich track, and it will take a shape of irregularly orange-peel surface On the premise of ensure the functional of the track,
it has good drainage function , Rain and snow in high latitude area can’t fall into the elastic layer,
the slope of the surface can drainage by natural when the climate warming ,the sandwich track is your best choice in the Alpine Cold Region .
3. Product advantage
- High-crystalline silicone pu buffer coat
- Water-based top coat
- Economic design
- Stable structure, good shock absorption and higher environmentally friendly
