PHENOLIC RESINS BROCHURE

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.
