Application

T-3000 is a reactive chain extender for polyurethane with typical primary amine reaction properties. It is widely used in the polyurethane RIM industry and is the main raw material for spray polyurea elastomers; because of its unique chemical structure, T-3000 plays a toughening role in the epoxy industry: together with polyamide, it is used in high-performance An epoxy adhesive characterized by high strength; it has surface anti-corrosion effects in both epoxy and polyurethane systems.
Safety performance and toxicity

T-3000 amino-terminated polyether is slightly toxic when taken orally; non-toxic when absorbed through the skin, but slightly irritating to the skin; highly irritating to the eyes; use protective gear to cover your face when loading and unloading T-3000. If it accidentally comes into contact with your eyes, you must immediately wash it with water for at least 5 minutes and conduct necessary medical observation. If it comes into contact with your eyes, wash it immediately with soap and water.
