1.System Description
The filler tapes are designed as an underlying filler materials prior to the application of coating systems.
-Flexible under various field conditions
-Conformable and moldable
-Easy and simply application
-Compatible with various coating system
2.PE repair patch
The product consists of an irradiated cross-linked polyolefin sheet coated with a heat activated adhesive and is designed specifically for sealing and protection of damaged pipeline coatings.
-No special tools or equipment required
-Excellent abrasion resistance
-Inert to common acids,alkalis and solvents
-Barrier to moisture and corrosion
3.Hot melt adhesive stick
Hot melt adhesive stick is composed of heat-activated adhesive with a stick form.It is used for repairing a small damage on the pipeline. It could be used as a filler material with PE repair patch.
4.Mastic filler
Mastic filler is used to fill larger voids and deep damaged coating prior to the application of PE repair patch.
Advantages
