USES and APPLICATIONS of ARADUR 3484:
Aradur 3484 is primarily used as a curing agent for solvent-free epoxy resin systems intended for civil engineering, industrial flooring, and protective coating applications.
Aradur 3484 is especially recommended for use with ARALDITE PY 3483, where the combination produces high-performance primers, self-leveling floor coatings, mortars, mastics, and protective coatings with excellent processing characteristics.
Aradur 3484 is widely employed in warehouses, factories, parking garages, manufacturing plants, food processing facilities, hospitals, laboratories, and commercial buildings where durable seamless flooring systems are required.
In construction and infrastructure projects, Aradur 3484 is used in epoxy repair mortars, industrial floor toppings, concrete protection systems, crack repair materials, and heavy-duty maintenance coatings.
The cured systems provide excellent adhesion to concrete, cementitious materials, steel, and mineral substrates while resisting mechanical wear, moisture, industrial chemicals, oils, fuels, salts, and cleaning agents.
Aradur 3484 is also suitable for protective primers applied before high-build epoxy coatings, improving substrate sealing and long-term corrosion protection.
Its low viscosity makes Aradur 3484 particularly suitable for highly filled epoxy formulations, allowing efficient incorporation of quartz, silica, mineral fillers, and pigments without significantly increasing application viscosity.
This characteristic makes Aradur 3484 a preferred curing agent for epoxy mortars, trowel-applied flooring compounds, and heavy-duty industrial maintenance materials where excellent workability and consistent curing are essential.
Applications of Aradur 3484: With liquid epoxy resins, preferably with Araldite PY 3483 for solvent free primers, coatings, self-levelling floorings, mortars and mastics.
Aradur 3484 is widely employed in self-leveling floor coatings, primers, mortars, mastics, and industrial protective coatings where easy application, reliable curing, and long-term durability are essential.
-Applications of Aradur 3484:
Metal/metal combinations with moderately fast movements and high loads.
Aradur 3484 is used successfully for lorry coupling sleeves, toothed gears, parts of car safety belts and carboot lock parts.
Bolts and levers in tractors and construction machines.
PROPERTIES of ARADUR 3484:
Anti-friction coating.
MoS2-fortified.
Heat-curing dry lubricant.
Excellent lubrication, high load-carrying capacity.
High flash point (hence particularly suitable for series production operations), high abrasion resistance, long service life.
BENEFITS of ARADUR 3484:
Aradur 3484 offers numerous advantages for formulators and applicators of industrial epoxy systems.
Aradur 3484's low viscosity significantly improves mixing efficiency and allows the production of highly filled formulations while maintaining excellent workability.
Aradur 3484 develops smooth and regular film surfaces under a wide range of curing conditions, reducing coating defects and improving overall finish quality.
Another major benefit is Aradur 3484's excellent resistance to water spotting and surface blush, even when curing under conditions of high humidity or relatively low temperatures.
This improves coating appearance and minimizes corrective surface preparation before applying additional coating layers.
The cured epoxy systems exhibit outstanding abrasion resistance, making them suitable for industrial floors exposed to heavy pedestrian traffic, forklifts, machinery, and mechanical wear.
Aradur 3484 also provides excellent chemical resistance against water, oils, fuels, cleaning agents, dilute acids, alkalis, and many industrial chemicals.
High adhesion to concrete and steel contributes to long service life and reduced maintenance costs.
The combination of excellent processability, reliable curing, and durable protective performance makes Aradur 3484 highly suitable for demanding industrial flooring and civil engineering applications.
PROPERTIES of ARADUR 3484:
When combined with Araldite PY 3483, Aradur 3484 will show:
• low viscosity and therefore easy processability
• low tendency to water spotting even at low temperatures and high humidity
• good, very regular film surfaces at different curing conditions
• good abrasion resistance
• good general chemical resistance
CHARACTERISTICS of ARADUR 3484:
Aradur 3484 is characterized by its modified polyamine adduct chemistry, low viscosity, balanced curing behavior, and excellent compatibility with solvent-free epoxy resin systems.
Aradur 3484 reacts efficiently with liquid epoxy resins to form highly cross-linked thermoset polymers possessing excellent mechanical strength, abrasion resistance, adhesion, and long-term durability.
Aradur 3484 supports consistent curing under ambient conditions while producing coatings with smooth, uniform film formation and attractive surface appearance.
A distinguishing characteristic of Aradur 3484 is its excellent application performance under difficult environmental conditions.
Unlike many conventional amine curing agents, Aradur 3484 demonstrates very low sensitivity to moisture during curing, reducing the occurrence of surface defects such as water spotting, amine blush, or whitening.
Aradur 3484's excellent flow properties also improve substrate wetting, allowing better penetration into concrete pores and enhancing adhesion.
These characteristics make Aradur 3484 particularly well suited for industrial flooring, primers, mortars, mastics, and heavy-duty protective coatings where processing reliability and long-term performance are critical.
STORAGE of ARADUR 3484:
Aradur 3484 should be stored in a dry place, preferably in the sealed original container, at temperatures between 2 and 40 °C.
Aradur 3484 should not be stored exposed to direct sunlight.
PROPERTIES of ARADUR 3484:
Aradur 3484 is engineered to provide excellent processing characteristics while maintaining high curing efficiency in solvent-free epoxy systems.
Aradur 3484's low viscosity enables rapid and homogeneous mixing with liquid epoxy resins, improves pigment and filler dispersion, and enhances penetration into porous mineral substrates such as concrete.
These characteristics contribute to improved coating uniformity, reduced air entrapment, and easier application by roller, brush, or self-leveling techniques.
Aradur 3484 exhibits excellent compatibility with epoxy flooring formulations and produces smooth, defect-free surfaces with consistent gloss and appearance.
One of the key performance characteristics of Aradur 3484 is its very low tendency to develop water spotting or surface whitening during curing under conditions of high humidity or low ambient temperature.
This makes Aradur 3484 particularly valuable for construction and maintenance projects carried out in challenging environmental conditions.
The cured epoxy systems develop strong adhesion, excellent abrasion resistance, and reliable chemical resistance while maintaining long-term mechanical durability and dimensional stability.
