聚脲彩砂20

固化后材料有韧性，很多聚脲在清理余料时很脆 腾博室聚脲韧性是非常好的,并且室外长期暴晒也不会粉化，开裂

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
