Description

1,2-Ethandiamin, N-(2-aminoethyl)-, Verbindung mit Methyloxiran Polymer mit Oxirane [[[(1R,4aS,10aR)-1,2,3,4,4a,9,10,10a-octahydro-1,4a-dimethyl-7-(1-methylethyl)-1-phenanthrenyl]methyl]imino]dialkylenether (mittlere Molmasse ca. 700 g/mol) is a specialized polyetheramine derivative, engineered to deliver high-performance characteristics in demanding formulations. This product is valued for its unique combination of a reactive amine backbone and a hydrophobic abietylamine-derived segment, offering enhanced compatibility and functionality in polymer systems. It is primarily sought by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries for its role as a curing agent, chain extender, or property modifier.

Application

Epoxy Curing Agent/Modifier: Used to cure epoxy resins, imparting flexibility, impact resistance, and improved chemical/water resistance in protective coatings and composites.
Polyurea & Polyurethane Systems: Acts as a chain extender or curative, contributing to the development of high-performance elastomers, sealants, and spray-applied linings with fast cure profiles.
Adhesive Formulations: Enhances the toughness, adhesion, and durability of structural and industrial adhesives.
Asphalt Modification: Improves the adhesion, elasticity, and aging resistance of polymer-modified asphalt for road construction and roofing membranes.
Fuel & Lubricant Additive Intermediate: Serves as a precursor for manufacturing dispersants and detergents that improve engine cleanliness and performance.
Concrete Additives: Used in formulations for concrete curing compounds and surface treatments to reduce dusting and improve durability.

Quality Control

Our polyetheramine products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as amine value, moisture content, color, and viscosity are strictly monitored. Certificates of Analysis (COA) detailing all test results are available upon request. Our manufacturing process adheres to ISO 9001 quality management principles to guarantee reliability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and easily oxidized; for long-term storage, consider purging the headspace with an inert gas (e.g., nitrogen) after each use. Keep away from heat, sparks, and open flame.
