特點 Properties：
GPU彩砂自流平系統繼承了GPU家族的所有物理和化學性能，又增加了美觀的特點，克服了環氧彩砂不耐磨的缺點，使彩砂地坪得到質的飛躍。
GPU sand leveling system inherits all the physical and chemical properties of GPU family, but also increases the aesthetic characteristics, to overcome the shortcomings of the epoxy does not wear sand, so sand floor to get a qualitative leap.
表面效果 Effect of surface：
單層無縫、無溶劑、平滑、啞光的聚氨酯地坪
Single seamless, solvent-free, smooth, matte polyurethane floor
厚度 Thickness：4-9毫米

4mm厚的GPU 彩砂自流平系統可以充分耐60℃的溫度；
6mm厚的GPU 彩砂自流平系統可以充分耐70℃高溫，且可以進行輕度蒸汽清洗；
9mm厚的GPU 彩砂自流平可以充分耐120℃高溫且完全可以用蒸汽清洗，因此需要設計非常優秀的基層系統。
4 mm thick GPU colour sand self-leveling system can make full 60 ℃ temperature resistance;
6 mm thick GPU colour sand self-leveling system can be fully resistant to high temperature of 70 ℃, and can be a modest steam cleaning;
9 mm thick of GPU colour sand self-leveling can fully 120 ℃ high temperature resistant and can steam cleaning, so need to design very good system at the grass-roots level.
