XUNDA EN 12068 C 50 coating system consists of XUNDA T 480 3 Ply inner tape 30 mils thickness and XUNDA T 250 2 ply outer tape 20 mils thickness
Features:
This product has been made by a special processing of butyl rubber to P.E. Its durability is strong and electric corrosion can be prevented. The pipe can be semi-permanently preserved which has an excellent effect on its corrosion resistance. It has a permanent and continuous adhesion effect, this outstanding combination of butyl rubber adhesion and P.E, make good weather resistance, outstanding electric and chemical characteristics and good workability for ease in both manual and machine work.
Usage:
1) Anti-corrosion of water pipe, gas pipe, oil pipe, etc
2) Anti-corrosion of electric wire, voltage and communication cable
3) Anti-corrosion of pipe in chemical factories having severe
moisture and corrosion
4) Anti-corrosion of various pipe lines
Application temperature : -34°C ~ 71°C
Service temperature : -34°C ~ 85°C

How to use?
1) Pipe surface processing
thoroughly clean the surface of the pipe by removing all foreign
material.
Completely remove any sharp projections from the area of the weld.
Remove all rust and/or other impurities using a steel brush.
2) Apply primer
Before application, shake or mix primer thoroughly.
Because it is highly volatile, make sure it is securely sealed
after use.
Because it contains inflammable solvents, use caution when working
near any open flames.
To obtain best results, apply primer in a temperature range of
0°C~25°C and for storage a
Temperature of -20°C~35°C is best.
Proper volume of primer is 100g per 1m².
When primer is applied and PE anti-corrosive tape is used, it is
recommended to apply the
tape within a short time after the primer is completely dry.
