TEGO AddBond LTK-B — Technical Profile
TEGO AddBond LTK-B is a Modified polyester (60% in butyl acetate, 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-B 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 butyl acetate, low Tg) |
| Function | Adhesion promoter |
| OH value | 25–30 mg KOH/g |
| Acid value | 12–30 mg KOH/g |

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-B Alternative?
Our SEMITECH Additives range offers functionally equivalent adhesion promoter resins that deliver the same performance as TEGO AddBond LTK-B — 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 (Modified polyester (60% in butyl acetate, low Tg)) ensures equivalent performance at the same dosage (1–15% based on total resin solids)
