C9 Hydrogenated Hydrocarbon Resins
C9 Hydrogenated Hydrocarbon Resins from the Velrez portfolio are high-purity, water-white aromatic resins developed for applications requiring excellent colour stability, oxidative resistance and strong compatibility with a wide range of polymers.
These resins are widely used in premium adhesive systems, hot melt technologies, coatings, inks and engineered formulations where clarity, low odour and high thermal stability are essential.
Velrez C9 hydrogenated resins are available in several versions: fully hydrogenated, partly hydrogenated and slightly hydrogenated grades – each supporting different performance needs.
Key Properties & Advantages
- Water-white appearance and excellent colour stability
- Low odour and improved thermal/oxidative resistance
- High compatibility with SIS, SBS, SEBS and other styrenic block copolymers
- Good adhesion and tackifying performance
- Enhanced durability in high-temperature and outdoor conditions
- Stable molecular structure through hydrogenation
- Available in a range of softening points for formulation flexibility
Applications & Industries
Velrez C9 Hydrogenated Resins are used in:
- Hot melt adhesives (HMA)
- Pressure-sensitive adhesives (PSA)
- Premium packaging adhesives
- Industrial adhesives and sealants
- Printing inks (high-clarity formulations)
- Coatings and varnishes
- Rubber and plastic modification
- High-performance engineered formulations

| Velrez W9Z1-130 | 95–105 | <0.4 | Partly hydrogenated | — | Sealants, coatings |
| Velrez W9Z2-100 | 95–105 | <0.4 | Slightly hydrogenated (high aromatic content) | — | Compounding, adhesives |
| Velrez W9Z2-120 | 115–125 | <0.4 | Slightly hydrogenated | — | High-performance coatings |
Fully hydrogenated grades provide the best colour stability and lowest odour.
Partly or slightly hydrogenated grades offer higher compatibility in certain aromatic systems.
Technical Characteristics
Velrez C9 hydrogenated resins are produced via advanced hydrogenation technology, resulting in:
- Increased molecular stability
- Reduced aromatic content (adjusted per grade)
- Lower colour and higher UV stability
- Enhanced resistance to oxidation and thermal degradation
Softening points range from ~95°C to 125°C, enabling formulation engineers to optimise viscosity, tack and adhesion performance.
These resins are particularly suitable when:
- Colour stability is critical
- Odour must be minimal
- Resistance to heat, oxidation and light exposure is required
- Compatibility with SEBS, SIS, SBS or EVA is essential
Polymer Compatibility
Velrez C9 hydrogenated resins are compatible with:
- SIS
- SBS
- SEBS
- EVA
- Hydrogenated C5/C9 blends
- NR and SBR blends
- Aromatic and aliphatic resin systems
- Paraffinic and naphthenic oils
