TEGO Twin 4000 — Technical Profile
TEGO Twin 4000 is a Siloxane gemini surfactant-based combined wetting and defoaming additive manufactured by Evonik Industries AG (Germany), part of the TEGO Twin product line. Replaces separate wetting+defoamer.
How It Works
TEGO Twin 4000 gemini surfactant structure combines two functional heads — one for substrate wetting (surface tension reduction) and one for defoaming (foam lamella destabilization) — on a single siloxane backbone. This dual-action eliminates the need for separate wetting and defoaming additives.
Key Specifications
| Property | Value |
|---|---|
| Chemistry | Siloxane gemini surfactant |
| Function | Wetting + defoaming (dual) |
| Active content | ~100% |
| Shelf life | 60 months |
| Dual-function | wetting + defoaming |
| Recommended dosage | 0.05–0.5% based on total formulation weight |
Applications
- WB/SB/UV coatings
Dosage & Addition
- Recommended dosage: 0.05–0.5% based on total formulation weight
- Addition point: Add during letdown
Formulation Considerations
Ideal for simplified formulations where additive count must be minimized. Not a replacement for high-performance dedicated wetting or defoaming in demanding applications.
Looking for a TEGO Twin 4000 Alternative?
Our SEMITECH Additives range offers functionally equivalent combined wetting and defoaming additives that deliver the same performance as TEGO Twin 4000 — 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 (Siloxane gemini surfactant) ensures equivalent performance at the same dosage (0.05–0.5% 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 Twin 4000 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
