D-2000
Product Name Polyetheramine
Model Number D-2000
Chemical Structure

Overview Description
D-2000 is a difunctional primary amine with an average molecular weight of approximately 2000. Its amino group is located on the second carbon atom at the end of the polyether. D-2000 has a density of 1.0 g/cm³ below 25℃, a flash point of 185℃, a melting point of -29℃, a pH of 10.5, and a boiling point of 250℃. D-2000 is characterized by its light color, low viscosity, and low vapor pressure. It is soluble in many solvents and slightly soluble in water.
Physicochemical Indicators
Applications
D-2000 terminal amino polyether is an active chain extender for polyurethane. It exhibits typical primary amine reaction properties. Due to its unique chemical structure, D-2000 has wide applications in the epoxy industry. In epoxy applications, it is rarely used alone; it is more often used with other curing agents, especially with other terminal amino polyether products such as D-230, D-400, and T-403. Using D-2000 effectively enhances the bending and tensile properties of epoxy products. One good application of D-2000 is in cathodic electroplating metal undercoating; D-2000 salt is a good diluent liquid.
Safety and Toxicity
D-2000 terminal amino polyether is slightly toxic by oral ingestion; it is non-toxic by skin absorption but mildly irritating to the skin; it is strongly irritating to the eyes. When handling or using D-2000, use a face shield. If accidentally contacted with eyes, immediately flush with water for at least 5 minutes and seek necessary medical attention. If spilled on skin, wash immediately with soap and water.
Packaging, Storage, and Transportation
D-2000 is usually packaged in 200 kg iron drums under nitrogen, stored away from light, heat, and moisture, with a shelf life of one year.
