Polyether amine application in SPUA and epoxy curing agent
Polyether amine(also known as polyether with Terminal amino, polyether polyamine) is a class of primary or secondary amino terminated polyalkylene oxide compounds, the molecular structure is a polyether, the reactive group is the amino group. Depending on the molecular weight & functional groups difference, available several grades and brand. specification.
Specific molecular structure determines its unique properties and special applications.
Polyether amine is the key raw materials for SPUA(Spray Polyurea Elastomer ). The product high-speed mixing with isocyanate and spray-formed a Spray polyurea elastomer has excellent physical and chemical properties, such as excellent tensile strength, elongation, abrasion resistance, anti-aging, corrosion resistance, tear resistance. For Polyether amine and isocyanate have fast curing ability, and no solvent, so that SPUA has very good construction performance and environmental performance, so the SPUA for a wide range of applications. It can be widely used in the basic protection of concrete, steel structure and other materials. Such as: truck wear lining, anti-corrosion coating of the bridge which across the sea, aseptic plant, the hospital's high-grade floor, high-end swimming pool wall protection decoration, land and sea oil pipelines inside and outside protection, deck, propeller Wear-resistant coating, temporary apron, sewage treatment tank leak, corrosion, urban waste dump leakproof, impermeable, anti-corrosion and sports venues, runways have a wide range of applications. Has been widely used in high-speed railway bridge waterproof, protective coating.
Polyether amine is also a new epoxy curing agent. Resins cured by it have excellent toughness, impact resistance and low temperature resistance. As curing exothermic peak low, the products is best choice for casting large epoxy resin components. Then the color value of the product is low, so that the solidified castings parts show crystal clear advantages. Therefore, Polyether amine is widely used in epoxy composite materials, epoxy coatings, epoxy electrophoretic coatings, adhesives, circuit boards, sealants, works of art and so on.
