I System description:

The XUNDA-T 800 is a hand wrapped heat shrinkable tape designed for corrosion protection of straight pipes, fittings, bends, elbows and other irregular configurations.. When heated the backing layer shrinks and the adhesive flows and forms a reliable corrosion protection seal onto metal and adjacent coating surfaces.

The Polyethylene Heat shrinkable Tape needs no primer nor patch closure and reduces application time and labour costs.

 

II Structure

The specification of the tape consists of three layers,

Adhesive: butyl rubber based hot melt adhesive

Film backing: polyethylene

Interleaf:Antiadhesive Film Treated with Silicone

 III Features

After heating, formed corrosion protection seal

Strong backing provides outstanding waterproofing effect

High chemical resistance. resists impact, abrasion and ultraviolet light.

Excellent resistance against cathodic disbondment, dielectric breakdown.

Simple Application

V Application

No Special skills, equipments, patch closure nor primer are needed. Its superior flexibility provides easy and reliable application for irregular configurations of fittings, bends and elbows and small diameter of straight pipes.

Wrap spirally the tape over foreign matters-free and preheated surface, beginning at least 25~50mm (1~2 ) onto pipe coating. Wrap the tape with enough tension to obtain conformability and with minimum 50% of overlapping, while removing the release liner. Warm the end part of the tape and press down firmly. Using a torch, start at the edge of the tape and heat circumferentially around the coated pipe.

Finish off by heating over the entire tape vertically to ensure a uniform adhesion and by using a roller or gloved hands to remove wrinkle and air.
