Product Description

Description

Long-Term Corrosion Protection Aluminum Foil Viscoelastic Tape for Metal Facilities (Over 30 Years), Primer-Free and Easy to apply
CYCT aluminum foil viscoelastic tape is an upgraded corrosion protection product based on CYCT type viscoelastic tape. Aluminum foil visco-elastic anticorrosion tape consists of new-type high-performance visco-elastic polyolefin materials and aluminum foil. It combines the characteristics of both solid and liquid adhesive materials into one. It can provide long-term and effective anti-corrosion protection for pipelines and metal facilities. The property of visco-elastic tape will last more than 30 years under normal conditions.

Features

Simple surface preparation and directly applied on steel, PE, PP, FBE without primer.
Compatible to 3LPE, CTE-coating and asphalt.
Excellent impermeability to water and oxygen.
Perfect chemical resistance.
Excellent weather resistance mainly depends on the aluminum foil film.
Applicable temperature -30℃~60℃.
Controllable construction quality and seldom affected by environment and operator skill.
An eco-friendly material to be stored for a long time.
Aluminum Foil Viscoelastic Tape
The adhesive layer has the characteristics of "permanently non-hardening" and "permanently maintaining high plasticity", and can be used for above-ground pipes and flanges. The sealing corrosion protection can also be used on building roofs, equipment surfaces, etc. that are exposed to the outdoors. It can be applied in wide range of climate environment and has excellent corrosion protection performance, strong weather resistance and anti-aging capabilities.
