Overview
JEFFAMINE D-230 is a difunctional, primary amine characterized by repeating oxypropylene units in its backbone, with an average molecular weight of about 230. Its primary amine groups are located on secondary carbon atoms at the end of the aliphatic polyether chain. As one of the recommended international brand products in our auxiliary agent range, it is supplied with supply chain resource support for formulators sourcing a low-viscosity polyetheramine for epoxy curing and hot melt adhesive applications.
Key Benefits of JEFFAMINE D-230
- Low viscosity, color, and vapor pressure
- Completely miscible with a wide variety of solvents, including water
- Provides tough, clear, impact resistant coatings, castings, and adhesives
- Coatings are free of surface blush prevalent with many amine curing agents
Applications
JEFFAMINE D-230 is primarily evaluated as an epoxy curing agent, and it also reacts with carboxylic acids to form hot melt adhesives and reacts quickly with isocyanates. Salts may be formed readily for surfactant use as well. This range of reactivity supports formulation work across paints and coatings, adhesives and sealants, and other applications evaluated by formulators in automotive and transportation, building and construction, electrical and electronics, and HI&I care end markets.
Why Low Viscosity and Blush-Free Curing Matter
Surface blush is a common defect in amine-cured epoxy coatings, appearing as a waxy or greasy film that forms when moisture in the air reacts with unreacted amine at the coating surface during cure. Because JEFFAMINE D-230 is formulated to produce coatings free of surface blush, formulators can avoid an extra cleaning or abrasion step before recoating or bonding that is otherwise common with many amine curing agents.
Low viscosity also matters for processing, since a lower-viscosity curing agent is generally easier to mix, meter, and apply than a high-viscosity alternative, particularly in casting and coating applications where uniform dispersion affects the clarity and impact resistance of the finished part. Formulators should always confirm current amine value, viscosity, and recommended stoichiometric ratios against the latest technical data sheet for their specific formulation.
What to Consider When Sourcing JEFFAMINE D-230
When sourcing a difunctional polyetheramine for epoxy curing, hot melt adhesive, or isocyanate-reactive applications, formulators typically evaluate amine functionality, molecular weight, water miscibility, and compatibility with the resin or isocyanate system already in use. Working with a supplier that can provide consistent documentation and responsive technical support can help reduce qualification time when approving a new curing agent for a coatings, adhesives, or castings production line.
Because this amine reacts quickly with isocyanates and readily forms salts for surfactant use, formulators working across these different reaction pathways should confirm current reactivity and dosage data against the latest technical data sheet, rather than assuming identical handling across every intended use case.
General Handling and Storage Guidance
As with most reactive amines, this product should be kept in tightly sealed original containers, stored in a cool, dry, well-ventilated location away from incompatible materials, and used within the manufacturer’s recommended shelf life. Because it is a reactive primary amine, containers should be kept away from strong oxidizers and handled according to the current SDS.
Shelf life and specific storage recommendations vary by batch and packaging format, so formulators should always confirm current shelf life, recommended storage conditions, and any handling precautions against the latest technical data sheet and SDS for the specific batch of this polyetheramine they are working with.
How This Polyetheramine Performs Across Curing, Bonding, and Surfactant Roles
As an epoxy curing agent, this amine contributes to a tough, clear, impact resistant cured film, which formulators weigh against the blush resistance and viscosity requirements of their specific coating, casting, or adhesive application. In hot melt adhesive formulation, it instead reacts with carboxylic acids to build the adhesive backbone, while its fast reaction with isocyanates supports a separate set of polyurethane-related formulations.
Because this amine is positioned across these curing, bonding, and surfactant roles, formulators evaluating it for a new system should confirm which reaction pathway, epoxy curing, carboxylic acid reaction, isocyanate reaction, or salt formation, is the priority for their formulation, since dosage and stoichiometry recommendations differ between these use cases.
