4. Applications

Polyether amine D-2000 can reacts as typical primary amines. Due to its fast reacting nature with isocyanates, it has found wide use in polyurethane and polyurea applications. In addition, it has found application and inconjunction with other polyamines. D-2000 formulated systems exhibit enhanced peel strengths. Besides, an intriguing application for Polyether amine D-2000 is in epoxy systems for metal priming via cathodic electrodeposition.

5. Safety

D-2000 has micro toxicity in oral administration; non-toxicity for skin absorption; weak irritation to skin, and strong irritation to eyes. Please use mask to protect the face when loading/unloading D-2000. If D-2000 contact the eyes accidentally, it is necessary to wash with water for at least 5 minutes, and conduct the required medical observation. Wash with water and soap in time if D-2000 contact with the skin.
