Tackifer Resins
Tackifer resins are used as an additive to impart tack in synthetic rubbers that do not
possess the inherent tack necessary for plied-up construction. The largest use for these
types of resins is in tire building. For tire building applications a typical usage is 3-8 phr.
Akrochem’s phenolic tackifer resins for this application and others like it are as follows:
GENERAL PURPOSE
SP-1068 (P-90)
SP-1068 is an unmodifed, thermoplastic resin made from octylphenol and
formaldehyde. It is typically used to increase tack in natural and synthetic elastomers,
including SBR, BR, IIR and IR. SP-1068 has the lowest temperature softening point of
our general purpose tackifer resins.
HRJ-4047 (P-165)
HRJ-4047 is an unmodifed, thermoplastic resin made from octylphenol and
formaldehyde. It is compatible with natural and synthetic elastomers, including SBR,
BR, IIR and IR. It is a good general purpose tackifer, similar to SP-1068, but with a higher
temperature softening point.
RIBETAK 7510P
Ribetak 7510P is an alkyl-phenol, thermoplastic resin. It is recommended for natural and
synthetic elastomers, including SBR, BR, IIR, IR, and EPDM. It is a good general purpose
tackifer similar to SP-1068.
