TEGO Phobe 1659 — Technical Profile
TEGO Phobe 1659 is a Silicone resin emulsion-based hydrophobic agent and water repellent manufactured by Evonik Industries AG (Germany), part of the TEGO Phobe product line. Capillary water uptake reduction.
How It Works
TEGO Phobe 1659 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
| Property | Value |

Dosage & Addition
- Recommended dosage: 1–8% based on total formulation weight
- Addition point: Add during letdown; ensure good dispersion
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 1659 Alternative?
Our SEMITECH Additives range offers functionally equivalent hydrophobic agent and water repellents that deliver the same performance as TEGO Phobe 1659 — matched surface tension reduction, compatibility profile, and application behavior — at 20–40% lower cost.
Why formulators switch to SEMITECH Additives:
