Polyamide Hardener (CAS NO : 68410-23-1)

Polyamide Hardener portfolio: By varying the dimer acid structure and amine functionality, we provide a spectrum of curing agents with diverse reactive profiles (Amine Values) and cross-linking densities (AHEW). This allows formulators to dial in the exact "Induction Time" & "Pot Life" required for complex field applications from rapid-cure maintenance to large-area maritime coating projects. Characterised by their superior "surface-wetting" properties, our Dromide series ensures excellent adhesion even on damp or manually prepared surfaces, significantly lowering the Total Cost of Quality by reducing substrate preparation requirements and extending the maintenance cycle. High-performance Polyamide Hardeners are meticulously engineered as critical curing agents for two-component epoxy systems, specifically optimised for the extreme demands of heavy-duty industrial and maritime environments. We are established Polyamide Hardeners suppliers, ensuring a consistent amine-value profile and precise AHEW (Amine Hydrogen Equivalent Weight) across the Dromide series. We provide a broad range of high-performance curing agents with comprehensive technical (Viscosity/Color/Amine Value) and supporting quality assurance documentation (Polyamide Hardeners grade COA/TDS/SDS), detailed compatibility mapping with standard epoxy resins, and global regulatory support. We ensure reliable lead times from project-specific evaluation to 10MT+ commercial-scale supply, enabling partners to maintain full adaptability in global marine and industrial coating sectors

Chemical Properties & Specifications

Applications of Polyamide Hardener

Marine Coatings & Ship Repair

Anti-corrosive primers and intermediate coats (tie-coats) on hulls, decks, and ballast tanks. Excellent resistance to saltwater, humidity, and mechanical abrasion

Heavy-Duty Industrial Maintenance

Optimised for protecting steel structures, bridges, and offshore platforms exposed to aggressive atmospheric conditions and chemical splash

Infrastructure & Civil Engineering

High-build (HB) topcoats for concrete and steel reinforcement, providing a durable barrier against carbonation and sulphate attack

Industrial Adhesives & Sealants

Toughening agent in structural adhesives, providing the high-impact resistance and peel strength required for large-scale industrial assembly

Epoxy Floor Coatings

Primers and screeds that require a degree of flexibility to prevent cracking under thermal or mechanical stress
