TEGO AddBond LTK — Technical Profile
TEGO AddBond LTK is a Modified polyester (60% in xylene, low Tg)-based adhesion promoter resin manufactured by Evonik Industries AG (Germany), part of the TEGO AddBond product line. 2025 launch.
How It Works
TEGO AddBond LTK modified polyester backbone contains carboxyl and hydroxyl groups that form strong bonds with metal surfaces (aluminum, steel, tin) through acid-base interaction and hydrogen bonding. The polymer chain simultaneously anchors into the coating resin matrix, bridging the coating-substrate interface.
Key Specifications
| Property | Value |
|---|---|
| Chemistry | Modified polyester (60% in xylene, low Tg) |
| Function | Adhesion promoter |
| OH value | 25–30 mg KOH/g |
| Acid value | 12–30 mg KOH/g |
| Tg | 20–70°C (grade-dependent) |
| Active content | 60–100% |
| Recommended dosage | 1–15% based on total resin solids |
Applications
- Can coatings
- Coil coatings
- Industrial
- Transportation
Dosage & Addition
- Recommended dosage: 1–15% based on total resin solids
- Addition point: Dissolve in resin/solvent before pigment grinding; can also be post-added
Formulation Considerations
LTH (solid, Tg 70°C) for hard coatings. LTW (solution, Tg 20°C) for flexible systems. LP 1600 is FDA food-contact approved for can coatings. LTK/LTK-B (2025) offer low viscosity for easy handling.
Looking for a TEGO AddBond LTK Alternative?
Our SEMITECH Additives range offers functionally equivalent adhesion promoter resins that deliver the same performance as TEGO AddBond LTK — matched surface tension reduction, compatibility profile, and application behavior — at 20–40% lower cost.
