Why use Tangit DTX Cement?

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

Characteristics

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

Resistability

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

Pipe Tolerances

Curing Times

Pressure Loads

Temperatures

Acid Type

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.
