Curatives

ETHACURE® Curatives - Complete control.

ETHACURE curatives are high purity, 100% active curatives that are easy to blend and handle without the use of costly heating steps. These diamine chain extenders/crosslinkers are used to cure polyurethanes, epoxies, and polyureas. Our liquid curatives allow formulators to easily adjust reaction times and eliminate dust exposure while improving product characteristics.

With a diverse portfolio of liquid curatives, decades of technical expertise, and a robust global supply chain, Albemarle is a reliable supplier of high quality products and solutions for even the most unique curative applications.

Curative Applications Description


ETHACURE® 100


DETDA 
(Diethyltoluenediamine)




ETHACURE® 100 Plus


  • Spray Polyurea Coatings
  • RIM
  • Polyurethane Coatings 
  • Cast Polyurethane
  • Epoxy Composites
  • Filament Winding

      The workhorse curative, especially for spray applications. In polyurea coatings, ETHACURE® 100 increases versatility and adjustability while enhancing product performance. In epoxy applications, cured parts display good “wetting” characteristics, high glass transition temperatures (Tgs), improved chemical resistance, and low moisture accumulation.

      DETDA in particular is used for RIM applications.

      ETHACURE® 100 Plus is a more color consistent version of ETHACURE® 100.


      ETHACURE® 100-LC
      • Polyurea Coatings
      • Cast Polyurethane
      • Polyurethane Coatings
      The lowest-colored aromatic diamine readily available. For applications requiring optical clarity, utilizing ETHACURE® 100-LC results in lower color in final parts, reduced pigment loading, easier color matching, and increased shelf life.
      ETHACURE® 270
      • Epoxy Composites
      • Filament Winding
      Formulated to provide longer, adjustable reaction times when working with epoxy resins, especially at ambient and elevated temperatures. ETHACURE® 270 cured polymers display high temperature performance, substantial mechanical strength, and good chemical resistance.
      ETHACURE® 300
      • Polyurea Sealants
      • Polyurethane Coatings
      • Cast Polyurethane
      ETHACURE® 300 is the leading low-toxic alternative for MOCA. This versatile, easy-to-handle liquid eliminates dust and hazardous material exposure. Recent advances in ETHACURE® 300 provides the material with reduced odor. Cured polymers display excellent strength, hardness, modulus, and elongation at break point.

      ETHACURE® 420
      • Spray Polyurea Coatings
      • Polyurea Sealants
      Often used in combination with ETHACURE® 100 to adjust curing rates in fast reacting systems, ETHACURE® 420 boosts polymer performance, particularly elasticity, surface finish, adherence capabilities, and pot life. ETHACURE® 420 makes it easy to produce the soft elastomers needed for caulks and sealants.
      ETHACURE® 520

      ETHACURE® 534
      • Polyurethane Coatings
      ETHACURE® 520/534 has favorable reactivity with a wide variety of prepolymers. Utlizing ETHACURE® 520/534 enhances the pot life and physical properties of the cured material.
