特点(Features and Benefits)
Ø 专门用于挤压聚乙烯防腐涂层的划伤、碰伤、气泡、剥离强度测定时的切口等损伤的补伤修复；与管线外PE防腐涂层的粘接强度高，形成连续紧密的防腐体系；
Ø 抗冲击、耐磨损、耐化学腐蚀、耐水汽渗透等性能好，环境适应能力强。
Ø Specially used in repairing the damaged PE-coating and PP-coating on steel pipeline, such as scratch, touch damage, air bubble, and cut of the peel strength test.Adhere closely to the surface of PE-coating and PP-coating on steel pipeline, and form a continuous close corrosion prevention system with the surface of the pipe.
Ø Anti-impact, wearability, chemical corrosion protection, water vapor penetration prevention. Easily adapt itself to the environment.
