Hanson Offers HXA CE 425 Aliphatic Diamine Chain Extender for Elastomeric PU Coatings

Published on 2012-11-05. Author : SpecialChem

HXA CE 425 helps the formulator adjust their formulation by slowing down the reaction rate compared to primary aliphatic amines. This also helps the processing of your system making it easier to apply.

HXA CE 425 is also designed to provide you with excellent processing characteristics with standard epoxy resins used in filament winding and resin infusion. HXA CE 425 is a safety type hardener with low vapor pressure, non-blushing and low viscosity. HXA CE 425 systems will be more robust and tougher in performance.


  • Outstanding Price-Performance Ratio Resulting in Overall Lower Formulation Costs?
  • Faster Film Property Development & Green Strength - Similar to Aromatic Polyureas
  • Ease of Formulation - Can be blended with various amine systems
  • Better System Thermal Stability - maintains properties at higher temperatures
  • Improved System Processability - "It Just Sprays Better"
  • Excellent UV & Color Stability
  • Slows down the gel time allowing better adhesion, flow & leveling and fiber penetration (especially for resin infusion processes)

HXA CE 425 is designed as a slow reacting, liquid chain extender for polyurea, polyurethane, and hybrid coatings and elastomer systems. HXA CE 425 is created as a toughened hindered amine for use as a crosslinker for epoxy matrix resins. It costs less and typical use levels are less than similar aliphatic secondary amines available today. This means longer gel times for less money. Try it and see the difference!

  • Light stable OEM Polyurea Elastomeric Coatings
  • Light stable top coats
  • Light stable Polyurethane Elastomers
  • Toughened non-blushing Epoxies for filament winding & resin infusion 425
