C9 Aromatic Hydrocarbon Resins
C9 Aromatic Hydrocarbon Resins are part of the Velrez product portfolio and are produced through catalytic polymerization of aromatic feedstocks. They are widely used across the coatings, printing inks, adhesives and rubber industries due to their excellent adhesion, pigment wetting, gloss enhancement and compatibility with aromatic polymers.
Velrez C9 resins offer strong technical performance, reliable batch consistency and are available in a broad range of softening points to support multiple formulation requirements.
Key Properties & Advantages
- Excellent adhesion and cohesive strength
- Strong pigment wetting and dispersion behaviour
- Improved gloss and hardness in coatings and inks
- High compatibility with aromatic polymers and elastomers
- Available in multiple softening point grades (95–155°C)
- Consistent colour stability and quality across batches
- Suitable for high-temperature and demanding applications
Applications & Industries
Velrez C9 Aromatic Resins are used in:
- Printing inks (gravure, flexographic, offset)
- Paints & coatings
- Rubber compounding (tire & technical rubber)
- Hot melt adhesives (HMA)
- Bitumen and asphalt modification
- Industrial adhesives and sealants

Technical Characteristics
Velrez C9 aromatic resins feature a softening point range from 95°C to 155°C, with colour levels ranging from <4 to <13 depending on the grade.
They provide strong tackifying performance, excellent pigment wetting and compatibility with a wide range of aromatic elastomers, including:
- SBR (styrene-butadiene rubber)
- SIS / SBS (styrene block copolymers)
- Natural rubber blends
- Aromatic modified resins
- Phenolic and alkyd systems
These characteristics make C9 resins essential in high-performance formulations requiring strong film formation, gloss, colour acceptance and mechanical strength.
Polymer Compatibility
Velrez C9 Aromatic Resins are compatible with:
- SIS
- SBS
- SBR
- NR blends
- Alkyd resins
- Other aromatic hydrocarbon resins
- C5/C9 modified resins
