Detail
Product Introduction
This product requires no primer application, and has no peeling, cracking or hardening issues. It features strong adhesion, good chemical resistance, and no cathodic protection disbondment. It completely prevents moisture intrusion and microbial corrosion, giving it unique long-term effectiveness.
Product Features
- Surface treatment requirement is as low as ST2/3 level, no need for sandblasting rust removal
- Can be directly applied to surfaces like steel, PE, PP, FBE, without primer
- Excellent sealing performance, which can completely block moisture and oxygen
- Minor defects can self-repair
- Good on-site operability, can be directly used for anti-corrosion of irregular components
- Wide operating temperature range: can be constructed in harsh environments from -30°C to 130°C, with simple and convenient operation
- On-site construction quality is easy to control, and it is less affected by the environment and personnel technical level
- Optional outer protective tapes: PVC/PE/PP tape, heat-shrinkable tape, fiber composite tape
- Proven by application in large domestic and international pipeline projects, with stable and reliable quality
Applied range
Butyl elastomer anti-corrosion tape features simple and convenient construction with low surface preparation requirements Manual rust removal to St2 level is sufficient to meet application needs The materials used are completely environmentally friendly, complying with modern anti-corrosion design concepts, making it an ideal product for anti-corrosion protection It can be widely applied in fields such as repair of anti-corrosion layers for oil and gas pipelines, repair of damaged 3PE anti-corrosion layers, and anti-corrosion protection of special-shaped equipment like flanges, valves, and pumps
