2020-12-14 09:00:49

As the key raw material of spray polyurea elastomer, the elastomer made from amino terminated polyether has excellent tensile strength, elongation, wear resistance, aging resistance, corrosion resistance and tear resistance. This component can make spray polyurea have excellent construction performance and environmental protection performance, so it is widely used in the protection of concrete, steel structure and other materials.


polyether


Amino terminated polyether is a new type of material which emerged in 1990s. The cured resin has excellent toughness, impact resistance and low temperature resistance. It is also an additive of engine fuel oil, which plays the role of anti deposition and is also an additive of lubricating grease, which is conducive to improving the wear resistance of parts. In addition, amino terminated polyether is widely used in surfactants, water-soluble coatings and adhesives.

The epoxy resin cured with polyether amine has a relatively long construction period and a low exothermic temperature peak. It can obtain colorless and transparent high gloss materials and improve the surface state of coatings. It is very suitable for casting and potting applications.

The cured polyether amine has good alkali and water resistance, and moderate acid resistance. The epoxy resin cured with polyether amine has good electrical properties. Polyether amines have unique properties and are involved in almost all epoxy applications, such as coatings, potting materials, building materials, composites and adhesives. Compared with other amine curing agents, polyether amine has low viscosity, light color, good compatibility with many organic substances, moderate reaction activity, and can meet the special application requirements.

When using amino terminated polyether, we must understand its performance, use method, storage matters, and even have an understanding of the storage container. Only in this way can we operate and use it better, and maintain the good performance of the product. Wrong operation, use and storage will have a certain impact on its purity and performance. Next Let's have a simple understanding of what we need to pay attention to when using it?

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.
