聚脲彩砂20
固化后材料有韌性，很多聚脲在清理余料時(shí)很脆 騰博室聚脲韌性是非常好的,并且室外長(zhǎng)期暴曬也不會(huì)粉化，開裂
The cured material is tough, and many polyureas are brittle when cleaning the remaining material The toughness of polyurea in Tengbo room is very good, and it will not be powdered and cracked when exposed to the sun for a long time outdoors
