Performance comparison of Feiyang Polyasdpartic Polyurea & Epoxy coating
Feiyang Polyaspartic Polyurea | Epoxy coating |
Not affected by temperature,-15℃-40℃,humidity≤85% can construct,and quick dry(30min-5h) | Hard to construct under low temperatures, need heat or other assistance, and is hard to cure under low temperatures. (above 48h) |
Good color stable and anti-QUV; color does not change, and no chalking for 15 years outdoors. | Good color stable and anti-QUV, easy to crack, delaminate. |
It can adjust to rigid and elastic, in which hard material possesses perfect hardness while keeping certain flexibility. | It can only do a hard coat and has low flexibility. |
Excellent anti-abrasion and anti-impact performance | Bad anti-abrasion and anti-impact performance, delaminate easily affected by an outside force. |
