Corrosion-Resistant Tape Primer

Corrosion-inhibiting Primer

Corrosion-inhibiting primer, along with inner polyethylene corrosion-resistant adhesive tape, outer polyethylene corrosion-resistant tape, and patch tape for polyethylene corrosion-resistant adhesive tape, collectively form the polyethylene cold-wrap corrosion protection system. Coated on surface-treated steel pipes, it not only fills in the fine irregularities on the pipe surface but also enhances the adhesion between the tape and the pipe, while also serving as an excellent corrosion inhibitor itself.

Product Structure

The undercoat is made by dissolving butyl rubber and adhesive resin in solvents such as ethyl acetate.

Product Specifications Model

The primer is available in two colors: black and orange yellow.
