Modified Cycloaliphatic Amine (Anchor 1040 Type)

Modified Cycloaliphatic Amine (Anchor 1040 Type) refers to a class of accelerated cycloaliphatic amine hardeners designed for room-temperature and mildly elevated temperature cure of epoxy systems with improved performance characteristics over standard cycloaliphatic amines. These products are produced by reacting cycloaliphatic amines with accelerating modifiers (phenols, reactive diluents, or Mannich-type reactions) to achieve faster gel time (20–40 minutes at 20°C), lower blushing tendency, and improved wetting at lower temperatures (down to 5°C) compared to pure IPDA or PACM. The "Anchor 1040" designation refers to a widely referenced commercial standard from the Anchor Chemical/Air Products range that defined high-performance fast-cure cycloaliphatic hardener characteristics; this product meets or exceeds those benchmarks. Applications include UV-stable composite laminates, marine topcoats, sports equipment, and production composite operations where both aesthetic (color stability) and structural performance are required. Typical mix ratio is approximately 30–40 phr for standard BPA epoxy. Pot life is 25–45 minutes at 25°C, extending to 60–90 minutes at 15°C.
