DESCRIPTION

ARADUR 3277 is a formulated polyamine adduct designed to react with compatible epoxy-functional resins.
ARADUR 3277 functions as a hardener, curing agent, crosslinker, and reactive polymerization component.

ARADUR 3277 is a multicomponent formulation rather than one chemically pure molecular substance.
ARADUR 3277 therefore has no single complete-product CAS number, EC number, molecular formula, or molecular weight.

ARADUR 3277 is supplied as a liquid polyamine adduct suitable for ambient-curing epoxy formulations.
ARADUR 3277 has a reported viscosity range of approximately 250–450 mPa·s at 25°C.

ARADUR 3277 has a reported amine value of approximately 450–500 mg KOH/g.
ARADUR 3277 has a representative active-hydrogen equivalent weight of approximately 91 g/eq.

ARADUR 3277 has a reported color value not exceeding approximately Gardner 6.
ARADUR 3277 appearance and color can vary slightly with storage history, temperature, and the applicable production specification.

ARADUR 3277 contains reactive amine hydrogen groups that open epoxy rings during the curing reaction.
ARADUR 3277 gradually converts the liquid resin-hardener mixture into an insoluble and infusible crosslinked network.

ARADUR 3277 curing is exothermic and becomes faster as the mixed mass or application temperature increases.
ARADUR 3277 pot life can therefore be considerably shorter in a large mixing container than in a thin applied coating.

ARADUR 3277 provides a representative gel time of approximately 80 minutes at 23°C in the documented standard epoxy reference system.
ARADUR 3277 gel time remains dependent on resin chemistry, batch size, starting temperature, fillers, pigments, and additives.

ARADUR 3277 has a comparatively high amine value that supports ambient-temperature epoxy curing.
ARADUR 3277 still provides sufficient processing time for appropriately sized self-leveling flooring batches.

ARADUR 3277 can be used at a representative level of approximately 50 parts per 100 parts of a standard liquid bisphenol-A epoxy resin by weight.
ARADUR 3277 exact dosage must be calculated from its active-hydrogen equivalent and the epoxy equivalent of the complete resin component.

ARADUR 3277 has been developed for self-leveling civil-engineering flooring systems.
ARADUR 3277 has also been documented as suitable for low-emission and solvent-free formulation concepts.

ARADUR 3277 is formulated without benzyl alcohol according to the available technical selector information.
ARADUR 3277 allows formulators to avoid a non-reactive diluent that could otherwise influence odor, emissions, migration, and long-term properties.

ARADUR 3277 performance depends on correct mixing, substrate preparation, temperature, humidity, and protection from early water exposure.
ARADUR 3277 cannot compensate for wet concrete, surface contamination, inaccurate proportioning, or incomplete component mixing.

ARADUR 3277 should be stored in tightly closed containers protected from moisture, excessive heat, direct sunlight, and contamination.
ARADUR 3277 storage life and exact temperature limits should follow the current regional technical and safety documentation.
