Containers for amino terminated polyether can be made of steel, aluminum, polyethylene or polypropylene. The storage temperature should not exceed 70 ℃. In order to prevent moisture absorption and oxidation, it is recommended to fill the container with nitrogen. We usually pack them in clean, dry, sealed, leak free galvanized iron drums. Keep away from the sun, rain and fire during storage. It is not restricted by the storage rules of flammable liquids, but it should be avoided to enter groundwater or surface water because it is not easy to be biodegraded.

Generally speaking, the toxicity of amino terminated polyether in oral cavity or in contact with skin, eyes and mucous membrane can be ignored, so personal protective measures are not necessary. But because of its alkaline will stimulate the skin and eyes, so the operation to wear safety glasses and gloves and other protective equipment.

The use of amino terminated polyether, I believe you have learned a lot in the past, today is mainly a lot of things for a simple string, I hope to be able to help you in the future.

Polyether amine is a kind of relatively widely used product. It can be used as a good auxiliary material to achieve certain effect, and accelerate the reaction speed. It is an excellent product. So what fields can it be used in?

(1) High performance composites: polyether amine can be used as a high-performance curing agent for epoxy resin to produce composite materials with high strength and toughness.

(2) Polyurea: as a key component of polyurea materials, it has many application examples in high-speed railway bridges, sea crossing bridges, dams, large stadiums and other concrete structures, and has shown excellent performance.

(3) Coating: polyether amine has low viscosity. When used in epoxy floor or anti-corrosion coating, it can reduce the amount of solvent and reduce the viscosity of the system.

(4) Adhesive: as a curing agent for epoxy resin, it has excellent toughness and fatigue resistance after complete curing, and is widely used in adhesives and structural adhesives.

(5) Jewelry: it has very light color and good yellowing resistance. Therefore, polyether amine can be used in jewelry manufacturing.
