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.

ETHACURE® 100 Plus
| ||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|| ||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|| ||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|| ||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|| ||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® 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.|
