Fast-reacting aliphatic amine-based curing agent designed for ambient-cure epoxy coatings.
Delivers excellent chemical resistance, particularly to alkalis, solvents, and mild acids.
Provides low viscosity and good compatibility with standard liquid epoxy resins (e.g., DGEBA types).
Enables high gloss, smooth film formation with minimal surface defects and low amine blush tendency.
Offers favorable pot life and film build control for spray, brush, and roller application methods.
Industrial floor coatings for warehouses, manufacturing facilities, and cleanrooms.
Protective coatings for concrete substrates in pharmaceutical and food processing environments.
High-performance maintenance coatings for steel structures in mild-to-moderate corrosion zones.
Interior architectural epoxy systems requiring rapid return-to-service and low VOC compliance.
Waterborne and solventborne two-component epoxy topcoats for non-submerged infrastructure.

Q1: What is the primary function of ARADUR 955 BD in epoxy coating systems?
A: ARADUR 955 BD is a low-viscosity, amine-based curing agent specifically designed to provide rapid cure development and excellent chemical resistance in high-performance epoxy coatings for industrial and protective applications.
Q2: Is ARADUR 955 BD suitable for ambient-cure applications?
A: Yes — it is formulated to enable efficient ambient-temperature curing of epoxy resins, making it well-suited for field-applied protective coatings where elevated oven curing is impractical or unavailable.
Q3: How does ARADUR 955 BD compare to traditional polyamide or aromatic amine curing agents?
A: Compared to conventional polyamides, ARADUR 955 BD offers faster reactivity and improved hardness development, while maintaining better flexibility and lower exotherm than many aromatic amines — supporting balanced performance in demanding coating formulations.
Q4: Can ARADUR 955 BD be used in high-solids or solvent-free epoxy coatings?
A: Yes — its low viscosity and favorable compatibility with standard liquid epoxy resins make it suitable for high-solids, low-VOC, and 100% solids epoxy coating systems without requiring excessive diluent addition.
Q5: What safety and handling considerations apply to ARADUR 955 BD?
A: As with all amine-based curing agents, appropriate personal protective equipment (PPE) — including gloves, eye protection, and adequate ventilation — should be used during handling to minimize skin contact and inhalation exposure. Always consult the current Safety Data Sheet (SDS) before use.
