JEFFAMINE D-220 is a difunctional, primary polyetheramine built on a repeating oxypropylene backbone, supplied by Huntsman and sourced by Thousands Technology for formulators across the epoxy, coatings, and adhesives supply chain. As a low-viscosity amine curing agent, it reacts with epoxy resins to deliver tough, clear, impact-resistant coatings, castings, and adhesive bonds while avoiding the surface blush common with many conventional amine hardeners.
JEFFAMINE D-220 Key Properties
This polyetheramine belongs to the polyoxypropylene diamine family registered under CAS 9046-10-0, with the primary amine groups positioned on secondary carbon atoms at each end of the aliphatic polyether chain. Per the Huntsman sales specification, the material is a colorless to pale yellow liquid with slight haze permitted, color 25 max Pt-Co, primary amine content of 97% minimum of total amine, total amine value of 7.6-8.2 meq/g, and water content of 0.20% maximum. Further structural and identification data for this compound family can be verified on PubChem.
This curing agent is produced to consistent lot-to-lot specifications, and Thousands Technology works with qualified supply partners to help buyers secure reliable access to this polyetheramine for ongoing production schedules rather than one-off purchases.
Key Features
- Low viscosity, low color, and low vapor pressure compared to many conventional amine hardeners
- Completely miscible with a wide variety of solvents, including water
- Provides tough, clear, impact-resistant coatings, castings, and adhesives
- Cured films are free of the surface blush prevalent with many other amine curing agents
Main Applications of JEFFAMINE D-220
As an epoxy curing agent, this product is formulated into clear casting and potting compounds, protective coatings, and structural adhesives where fast cure and low color retention are priorities. Buyers sourcing epoxy resin systems for composite tooling, flooring, or electronics encapsulation often pair it with complementary additives to fine-tune pot life and final hardness.
Because formulation performance depends on consistent amine value and purity, composite manufacturers and adhesive producers typically qualify this material against a documented specification sheet before scaling up purchase volumes, and maintain a secondary sourcing channel to reduce exposure to single-supplier disruptions.
Safety and Handling Considerations
This curing agent should be stored in tightly sealed containers away from moisture and strong oxidizers, consistent with standard practice for reactive amine curing agents. Handlers should use appropriate personal protective equipment, as amine compounds of this type can cause skin and eye irritation on direct contact. Full handling, storage, and exposure guidance is provided in the product SDS, which Thousands Technology can supply alongside the TDS on request.
