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.

Advantages:

-No special tools or equipment required

-Excellent abrasion resistance

-Inert to common acids,alkalis and solvents

-Barrier to moisture and corrosion

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.

Advantages:

-Flexible

-Excellent adhesion

-Flows into hard-to-reach location

-Excellent moisture resistance

Mastic filler :

Mastic filler is used to fill larger voids and deep damaged coating prior to the application of PE repair patch.

Advantages:

-Flexible under various field conditions

-Conformable and moldable

-Easy and simply application

-Compatible with various coating system
