Special Adhesive for the bonding of thermoplastic pipe systems under pressure. Especially suited for acid-proof piping made of PVC-C and PVC-U used in chemical plants.

Tangit Dtx Special Adhesive

Why use Tangit DTX Cement?

Tangit DTX is designed for use in critical media applications such as with aggressive acids and alkalis.



  • checkmark  For bonding of thermoplastic U-PVC piping systems under pressure acc. EN ISO 15493
  • checkmark  For critical media (see table below)
  • checkmark  Solvent-containing adhesive based on Tetrahydrofuran (THF stabilized)
  • checkmark  Gap filling and Thixotropic
  • checkmark  If used in combination with C-PVC piping systems max. temperature is 60 °C (like U-PVC)
  • checkmark  Tangit DTX complies with the requirements of EN 14814; Adhesives for thermoplastic piping systems for fluids under pressure
  • checkmark  CE Marking and DoP (01011)

Although all bonded joints are waterproof. Their chemical resistance, especially to inorganic acids, depends on:

  • checkmark  Pipe Tolerances
  • checkmark  Curing Times
  • checkmark  Pressure Loads
  • checkmark  Temperatures
  • checkmark  Acid Type
  • checkmark  Concentrate

In general, bonded joints made of ABS, PVC-U or PVC-C that are produced using the respective Tangit adhesive are as resistant as the material the pipeline is made of.



Critical Media

When exposed to the below media, it is recommended to use Tangit DTX Special Adhesive for producing bonded joints made of U-PVC or C-PVC.
As these media affect pipe material, it is also recommended to use pipes with a pressure rating PN 16.

Medium Concentration
Sulphuric Acid > 70% - ≤ 93% H2SO4
Hydrochloric Acid > 25% - ≤ 37% HCl
Nitric Acid > 20% - ≤ 55% HNO3
Sodium Hypochlorite > 6% - ≤ 15% NaOCl active chlorine
Hydrogen Peroxide > 5% - ≤ 70% H2O2

The DF (Derating factor) is always min. 1.6.
