TEGO Phobe 1401 — Technical Profile
TEGO Phobe 1401 is a Aminofunctional siloxane emulsion-based hydrophobic agent and water repellent manufactured by Evonik Industries AG (Germany), part of the TEGO Phobe product line. Water-beading effect.
How It Works
TEGO Phobe 1401 aminofunctional polysiloxane or silicone resin particles orient at the coating surface during drying, presenting hydrophobic methyl groups outward. This creates a water-beading (lotus effect) surface that repels rain, reduces dirt pickup, and prevents efflorescence on mineral substrates.
Key Specifications

Formulation Considerations
Phobe 6500/6600 are impregnation agents (penetrate porous substrates). Phobe 1401/1401 N are film-forming (stay in coating layer). Choose based on whether you need surface hydrophobicity or substrate protection.
Looking for a TEGO Phobe 1401 Alternative?
Our SEMITECH Additives range offers functionally equivalent hydrophobic agent and water repellents that deliver the same performance as TEGO Phobe 1401 — matched surface tension reduction, compatibility profile, and application behavior — at 20–40% lower cost.
Why formulators switch to SEMITECH Additives:
- Drop-in replacement — no reformulation needed in most systems; matched chemistry (Aminofunctional siloxane emulsion) ensures equivalent performance at the same dosage (1–8% based on total formulation weight)
