Polyamide Hardener Dromide adhesive series is characterised by its superior mechanical properties, specifically designed to eliminate the inherent brittleness of pure epoxy resins. By varying the chemical backbone and amine functionality, we provide a range of hardeners that allow for precise control over the final bond's flexibility and strength. From the high tensile shear strength of Dromide 9307 to the specialised sealant properties of Dromide 9366, our portfolio enables manufacturers to optimise their Total Cost of Quality through improved assembly speed and reduced long-term bond failure. Our high-performance Polyamide Hardeners for Adhesives are specifically formulated to meet the rigorous bonding requirements of structural engineering and industrial assembly. These curing agents provide the critical fracture toughness and impact resistance needed for epoxy-based adhesives to perform under mechanical stress and environmental extremes for high-stakes industrial assembly. We are authorised Polyamide Hardeners supplier for the adhesive industry, providing a broad range of speciality curing agents with consistent amine values and high fracture toughness. We provide comprehensive technical (Amine Value/AHEW/Viscosity) and supporting quality assurance documentation (COA/TDS/SDS), detailed shear-strength profiling, and global regulatory support. We ensure reliable lead times from pilot-batch evaluation to commercial-scale supply, enabling partners to maintain high structural reliability in global adhesive manufacturing.

Chemical Properties & Specifications
Automotive, aerospace, and general engineering adhesives, offering high tensile shear strength and exceptional durability
High-viscosity formulations that require sag resistance and high-performance sealing in construction and manufacturing joints
Engineered for high-load fillers and putties, providing a tough, non-brittle matrix that restores the structural integrity of concrete and metal substrates
Provides a flexible, stress-relieving bond for delicate electronic assemblies, surviving thermal cycling without delamination
Essential for secondary bonding of fiber-reinforced plastics (FRP) and maritime assembly where high-moisture resistance and peel strength are mandatory
High-viscosity hardeners (60,000–90,000 cPs) provide the necessary "body" and sag resistance for vertical and overhead repairs. This ensures that the putty stays in place during curing, preventing material waste and reducing the need for multiple applications. For procurement, this results in higher labor efficiency and a more reliable structural repair, lowering the overall maintenance expenditure.
PHR is a stoichiometric calculation based on the AHEW of the hardener and the EEW of the resin. For a grade like Dromide 9307, maintaining the precise PHR of 126 ensures that every epoxide group is cross-linked. Over- or under-dosing leads to a brittle or soft bond line. Scientists value our tight spec control because it guarantees consistent structural performance in automated assembly lines.
We support large-scale industrial manufacturing with a standard lead time of 7–8 Weeks for volumes up to 5MT. All products are offered Ex-Works and are typically supplied in 200 Kg MS Drums or 1,000L IBCs, ensuring the reactive amine groups are protected from atmospheric moisture.
Dromide 9435 is engineered with a specific amine-adduct structure that moderates the initial exothermic reaction. This allows for a longer working window (pot life), which is essential for large-scale bonding projects or complex manual assemblies. Once the induction period passes, the cross-linking accelerates to achieve a high-strength bond, providing the workability needed for precision manufacturing.
