C9 Aromatic Hydrocarbon Tackifier Resin
C9 Aromatic Hydrocarbon Resin is a thermoplastic tackifier produced by cationic polymerization of vinyl aromatic monomers (styrene, vinyltoluene, indene) from the C9 fraction of naphtha cracking. It imparts high tack, excellent adhesion to polar substrates, and good compatibility with SBS, SBR, and neoprene rubbers. C9 resins are widely used in solvent-based adhesives, printing inks, and rubber compounding where higher aromatic content and amber color are acceptable.
