TAPE & PRIMER APPLICATION Rust Removal Priming Wrapping Tape

Rust Removal Steel Surface needs treating. Its quality shall reach Sa 2 or St 3 grade as prescribed in GB 8923 -88 Pre-paint Steel Surface Rust Grade and Rustremoval Grade, and it shall be dust-free.

Priming Primer shall be stirred well before painting. An even film of primer is painted on the steel surface that is rustremoved completely and dust-free. After the primer dries up (one may feel no sticky). The steel pine can be wrapping with tape (it usually takes 3 to 5 minutes). The primer dosage usually amounts to 80 to 100 g / m 2.

Inner Tape & Outer 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 100 mm. each film shall be paralleled, and must not be twisted and rumpled.

Storage Product must keep dry and keep Away from Moisture and store indoor. Be aware of Primer must keep away from fire during the transportation, application and store.
