Performance advantage
1.Surface treatment requirement only needs to reach ST2/3 level, no borax rust removal required;
2.Can be directly applied on the surface made of steel, PE, PP, FBE, etc. without requiring primer;
3.Excellent chemical resistance and sealing, it is complete waterproof;
4.Slight defects can be self-repaired;
5.Can be directly applied to anti-corrosion of special-shaped components due to its convenient on-site operation;
6.Wide application temperature range (-30°C ~130°C). It can be installed between -30°C ~60°C.
7.The on-site construction quality is easy to control. It is slightly affected by the environment and technical skills of personnel;
8.It can be stored in long time and the material it adopts is eco-friendly;
9.Application practices of large-scale pipeline engineering at home and abroad show that the quality of the product is stable and reliable.

Application method:
1. Remove rust, weld seam, burr, oil stains, and then dry the surface before using the viscoelastic anti-corrosion adhesive tape. The surface treatment requirement only needs to reach level ST2/3, no borax rust removal required. After rust removal, treat the defects on the steel pipe surface. Clean up the dust and abrasives attached to the surface. Keep the surface of the steel pipe dry. In case of re-rust or surface contamination, carry out surface pretreatment once more.
2. Paste the viscoelastic plaster to the site to be fixed where necessary, and then paste the viscoelastic anti-corrosion adhesive tape.
3. Tear off the release film before pasting the viscoelastic anti-corrosion adhesive tape.
