TEGO Wet 296 — Technical Profile
TEGO Wet 296 is a Polyether siloxane in DPM-based substrate wetting agent manufactured by Evonik Industries AG (Germany), part of the TEGO Wet product line. 52% solution.
How It Works
TEGO Wet 296 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 in DPM |
| 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 296 Alternative?
Our SEMITECH Additives range offers functionally equivalent substrate wetting agents that deliver the same performance as TEGO Wet 296 — 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 in DPM) 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 296 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
