C5 Modified C9 Hydrocarbon Resin
C5–modified C9 hydrocarbon resins are aromatic–aliphatic tackifiers produced through catalytic polymerization.
They combine the compatibility of C9 resins with the improved balance of adhesion, color and viscosity contributed by C5 modifiers.
These resins are widely used in hot melt adhesives (HMAs), solvent-borne adhesives (SB), coatings and rubber formulations.
Key Properties & Benefits
- Balanced aliphatic–aromatic compatibility
- Improved adhesion and cohesive strength
- Good thermal stability during processing
- Suitable for HMA and solvent-based adhesive systems
Applications / Industries
This resin is used in applications such as:
- Hot melt adhesives (HMAs)
- Solvent-borne adhesives (SB adhesives)
- Pressure-sensitive adhesives (PSAs)
- Coatings
- Rubber compounding
- Sealants
(Selected for relevance to C5-modified C9 resins.)
