Description
Butyl Sealing Mastic Tape for Precast Manhole
Description
The main raw material is imported from foreign, which guarantees the stability of product quality at the source, and has a certain amount of adhesion and sealing performance to the abrasive tools and pinhole belt mills.
It is a preformed butyl joint sealant that is supplied in roll form. It is carefully blended from uncured butyl rubber and other solids and will not shrink, crack, or dry out.
