CYCT
1 / 1
Can be directly applied to steel, PE, PP and FBE coated surfaces without primer.
Well-matched with 3LPE/PP coating, FBE coating, CTE coating and asphalt materials.
Strong blocking capability against water and oxygen, preventing the intrusion of corrosive media.
Outstanding chemical corrosion resistance, suitable for complex environments.
Applicable to field joint anticorrosion, repair of damaged coatings, and protection of irregular fittings such as elbows, bends, T-joints and insulated flanges.
CYCT viscoelastic tape meets a wide temperature application requirement from -30°C to 95°C.
Stable construction quality, minimally affected by environmental factors and operator skills.
An environmentally friendly material with long-term stable storage performance.
