TEGO Wet 288 — Technical Profile
TEGO Wet 288 is a Polyether siloxane-based substrate wetting agent manufactured by Evonik Industries AG (Germany), part of the TEGO Wet product line. 2025 launch.
How It Works
TEGO Wet 288 reduces the dynamic surface tension of the coating at the substrate interface, enabling uniform wetting of difficult substrates (oily metals, low-energy plastics, contaminated surfaces). The polyether-modified siloxane structure provides rapid dynamic surface tension reduction without excessive foam.
Key Specifications
| Property | Value |
|---|---|
| Chemistry | Polyether siloxane |
| Function | Substrate wetting agent |
| Active content | 52–100% (varies by grade) |
| Dynamic surface tension reduction | 25–35 mN/m → 20–25 mN/m at 10 ms bubble age |
| Shelf life | 24 months |
| Recommended dosage | 0.1–1.0% based on total formulation weight |
Applications
- Waterborne coatings
- Solvent-borne coatings
Dosage & Addition
- Recommended dosage: 0.1–1.0% based on total formulation weight
- Addition point: Add during letdown or post-add; good shear stability
Formulation Considerations
Terra grades (570, 580) are 100% bio-based biosurfactants — ideal for eco-label formulations (EU Ecolabel, Nordic Swan). Wet 500 is silicone-free for systems requiring zero silicone.
Looking for a TEGO Wet 288 Alternative?
Our SEMITECH Additives range offers functionally equivalent substrate wetting agents that deliver the same performance as TEGO Wet 288 — 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 (Polyether siloxane) ensures equivalent performance at the same dosage (0.1–1.0% based on total formulation weight)
- Competitive pricing — 20–40% cost advantage vs. Evonik list price, with volume tier discounts available
- Reliable supply — direct from manufacturer in China, 2–4 week lead time, safety stock programs available
- Technical support — formulation assistance, application testing, and side-by-side comparison data provided
- Flexible MOQ — from 25 kg trial drums to 20-ton container loads
- Quality assurance — ISO 9001 certified, batch-to-batch consistency with full CoA
Qualification Process
- Request sample — we ship 1–5 kg free sample of our TEGO Wet 288 equivalent
- Lab testing — side-by-side evaluation in your formulation at equivalent dosage
- Application testing — confirm performance on your production equipment
- Qualification — full TDS, CoA, and regulatory documentation provided
- Scale up — seamless transition to production quantities
