DESCRIPTION

ARADUR 3290 is a polyamine adduct formulated as a reactive curing agent for epoxy resin systems.
ARADUR 3290 functions as a hardener, crosslinker, accelerator, and thermoset-forming component.

ARADUR 3290 is a multicomponent formulation rather than one chemically pure molecular substance.
ARADUR 3290 therefore has no single complete-mixture CAS number, EC number, molecular formula, or molecular weight.

ARADUR 3290 is supplied as a low-viscosity liquid suitable for ambient-curing construction coatings.
ARADUR 3290 has a reported viscosity range of approximately 100–180 mPa·s at 25°C.

ARADUR 3290 has a reported amine value of approximately 820–900 mg KOH/g.
ARADUR 3290 high amine value reflects a substantial concentration of basic and reactive amine functionality.

ARADUR 3290 has a representative active-hydrogen equivalent weight of approximately 48 g/eq.
ARADUR 3290 active-hydrogen equivalent is used with the epoxy equivalent weight to calculate a starting stoichiometric ratio.

ARADUR 3290 has a reported maximum color of approximately Gardner 4.
ARADUR 3290 actual appearance can vary slightly with production specification, storage history, temperature, and aging.

ARADUR 3290 contains reactive amine hydrogen groups that open epoxy rings during curing.
ARADUR 3290 converts the liquid resin-hardener mixture into an insoluble and infusible crosslinked material.

ARADUR 3290 curing is exothermic and accelerates as the mixed mass or application temperature increases.
ARADUR 3290 can therefore develop a substantially shorter container life in a large batch than in a thin applied film.

ARADUR 3290 provides a representative gel time of approximately 22 minutes at 23°C in the documented reference system.
ARADUR 3290 gel time varies with resin chemistry, batch size, starting temperature, fillers, pigments, and additional accelerators.

ARADUR 3290 relatively short gel time supports rapid property development in construction applications.
ARADUR 3290 short gel time also requires organized application procedures and appropriately sized mixing batches.

ARADUR 3290 low viscosity facilitates weighing, pumping, pigment dispersion, filler incorporation, and substrate wetting.
ARADUR 3290 low viscosity can reduce the need for large quantities of non-reactive processing solvent in suitably designed systems.

ARADUR 3290 performance depends on accurate proportioning and complete mixing with the selected epoxy resin.
ARADUR 3290 incorrectly mixed systems can remain soft, sticky, brittle, under-cured, or chemically nonuniform.

ARADUR 3290 should be evaluated for application temperature, substrate moisture, humidity, film thickness, and early water exposure.
ARADUR 3290 cannot compensate for wet concrete, poor surface preparation, contamination, or unsuitable environmental conditions.

ARADUR 3290 should be stored in tightly closed containers protected from moisture, excessive heat, acids, oxidizing agents, and contamination.
ARADUR 3290 exact storage temperature and shelf life should follow the current grade-specific technical documentation.
