Soy-Based Alkyd for Offset Ink Vehicle
CAS Number: 9016-88-0
Soy-oil-modified alkyd resin serves as a renewable, low-aromatic vehicle for sheetfed and heatset offset inks, imparting excellent pigment compatibility, controlled tack, and oxidative drying. Soy alkyd vehicles meet increasingly stringent VOC and bio-content requirements in commercial printing and packaging, and are preferred for food-packaging adjacent applications where mineral oil limits apply.
Technical Specifications
| appearance | Clear to pale amber viscous liquid |
| oil length (%) | 55–75 |
| viscosity (mPa·s) | 3000–15000 (25 °C) |
| acid value (mgKOH/g) | 3–12 |
| bio-based content (%) | ≥60 |
Applications
- Soy-based sheetfed offset inks for eco-label products
- Low-migration food-adjacent packaging inks
- Commercial printing inks meeting bio-content standards
- Heatset offset ink vehicles with low aromatic content
- Newsprint inks with renewable vehicle content
Key Features
- High renewable content for reduced carbon footprint
- Low aromatic mineral oil content for food-packaging compliance
- Good drying response with standard Co/Mn drier packages
- Comparable print quality to petroleum-based offset vehicles
