TEGO VariPlus CA — Technical Profile
TEGO VariPlus CA is a Ketone-aldehyde resin-based co-binder resin for hardness, scratch resistance, and gloss manufactured by Evonik Industries AG (Germany), part of the TEGO VariPlus product line.
How It Works
TEGO VariPlus CA ketone-aldehyde or polyurethane polyol hard resin dissolves into the main binder system, raising the overall Tg and crosslink density of the cured film. This increases pencil hardness, mar resistance, and gloss retention without requiring a harder (more brittle) primary resin.
Key Specifications
| Property | Value |
|---|---|
| Chemistry | Ketone-aldehyde resin |
| Function | Co-binder resin |
| Tg | 90–129°C (grade-dependent) |

Applications
- Coatings
- Printing inks
Dosage & Addition
- Recommended dosage: 5–30% based on total resin solids
- Addition point: Dissolve in resin during formulation
Formulation Considerations
SK (solid ketone resin) for solventborne and UV systems. DS 50 (aqueous PU dispersion) for waterborne. Both improve pigment wetting as secondary benefit.
Looking for a TEGO VariPlus CA Alternative?
Our SEMITECH Additives range offers functionally equivalent co-binder resin for hardness, scratch resistance, and glosss that deliver the same performance as TEGO VariPlus CA — 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 (Ketone-aldehyde resin) ensures equivalent performance at the same dosage (5–30% based on total resin solids)
- 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 VariPlus CA 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
