Self adhesive asphalt bitumen tape

Bitumen anticorrosion tape

Our company adopt the German technology, and the most advanced international formulations suitable for the manufacture of light steel structure waterproof anti-corrosion materials, low cost, higher than the life of the steel structure itself 1-2 times, environmental materials to fill gaps in the domestic bitumen anticorrosion tape steel structure waterproofing !

Product description:

The product is a kind of polymer modified asphalt materials, using polyester carpet or glass mat for the matrix, the surface covered with polyethylene film, aluminum foil or fine sand, the back is covered with a release sheet,keep the self-adhesive modified bitumen flexible and waterproof. The product has a good self-adhesive and bending properties.

Application:

Construction and other base face is simple, clean, and can be widely used in roofing, basement, bathroom, etc. waterproofing works, and for legislation to pave and stick and pipe wall (except heat pipes), bridges , and other complex environment, especially in open flame is prohibited, covert fire waterproofing works.

Product Features:

Self-adhesive modified bitumen membrane with a self-adhesive surface of the waterproofing, sealing material, divided into with base membrane and without base membrane.And one side with self-adhesive layer and two sides with layers two kinds.The self-adhesive layer has covered with release sheept. the material of realease sheet also has a few kinds. all the self-adhesive layers no need glue, just because the adhesive of itself, which is acaused by the modified bitumen. Low-temperature-resistant properties of the product, and the MTR, tunnels and the scene of the fire with the best waterproof, moisture resistance and sealing materials, also apply to pipeline waterproof, anti-corrosion works.

Application

1 Rust Removal

Steel Surface needs treating. Its quality shall reach Sa2 or St3 grade as prescribed in GB8923-88 Pre-paint Steel Surface Rust Grade and Rust-removal Grade, and it shall be dust-free.

2 Priming

Primer shall be stirred well before painting. An even film of primer is painted on the steel surface that is rust-removed completely and dust-free. After the primer dries up (one may feel no sticky). The steel pipe can be wrapping with tape (it usually takes 3 to 5 minutes). The primer dosage usually amounts to 80 to 100g / m².

3 Inner Tape (Anti corrosion Tape) & Outer Tape (Protection Tape) Wrapping

The steel pipe that is painted with primer is wrapping with tape by means of suitable devices or tools as per joint needs, and wraps the inner tape and then wraps the outer tape. Tape tensibility can be 10 to 20 N / cm. The overlapped length between beginning and end of an adhesive tape shall be no less than 1/4 circumference of the steel pipe and the total length of adhesive tape shall be no less than 100mm. each film shall be paralleled, and must not be twisted and rumpled.
