Hardener ATK 02.1 is a polyamide hardener for composite materials, featuring excellent adhesion, flexibility, and moisture resistance. Polyamide hardeners belong to the class of thermosetting polymers that cure through a condensation reaction with epoxy or other acid‑base resin systems, forming a highly cross‑linked network with strong covalent bonds. The inherent polarity of polyamides provides excellent wetting of reinforcing fibers such as glass, carbon, aramid, and Kevlar, which translates into superior load transfer and impact resistance in the final composite. ATK 02.1 is therefore widely used in industrial flooring where the substrate must endure mechanical shocks, chemical spills, and temperature swings from –30 °C to +80 °C, as well as in the fabrication of pipe linings, chemical storage tanks, and automotive structural parts that demand high moisture tolerance and fatigue resistance. The recommended mixing ratio with epoxy resin is 100 parts resin to 50–60 parts hardener, delivering a workable viscosity and a cure time that typically ranges from 30 minutes to 2 hours at ambient temperature. For faster cure cycles, small amounts of amine or organic acid accelerators can be introduced, but the dosage must be carefully controlled to preserve the flexibility of the cured matrix. Storage guidelines advise keeping the hardener above +5 °C, protected from direct sunlight and excessive humidity to prevent premature hydrolysis. During handling, protective gloves and safety glasses are recommended because polyamide hardeners may cause skin irritation with prolonged contact. The high moisture resistance of ATK 02.1 stems from its hydrophobic polymer chains, making it especially suitable for environments with elevated humidity such as warehouses, manufacturing halls, and sports facilities. Its flexibility allows the production of seamless, crack‑free floors that can absorb dynamic loads without failure. Global Optimals offers hardener ATK 02.1 at a competitive price in Tashkent.

The ATK 02.1 hardener must be stored in a dry, well‑ventilated area at ambient temperatures, typically between +15 °C and +25 °C, protected from direct sunlight and heat sources. Maintain the integrity of the original container; it should remain sealed and free from damage to preserve performance. Use clean tools, wear protective gloves and safety glasses, and ensure adequate ventilation during handling. For long‑term storage, periodically inspect the packaging for any breach and, if necessary, transfer the material to a tightly sealed secondary container.
