IRO Polyetheramine D Series is a kind of diamine on copolymer backbone.Its average MW is about 220-2000, with amino lying in on the second carbon of polyether end. They are light in color, low in viscosity, low in vapor pressure and high in primary amine content; can be dissolved in various solvents and slightly dissolved to water.
IRO polyether amine D series products are our core products. They are diamine terminated PPG (polypropylene glycol) with the following representative structure:
|Apperance||Colorless to pale yellow transparent liquid|
|Amine Value||0.95-1.05 mmol/g||4.10-4.70 mmol/g||8.10-8.70 mmol/g|
As a new style curing agents of epoxy, IRO Polyetheramine D series is mainly used in tough, clear, flexible, impact-resistant coatings, castings and adhesive. Usually, IRO Polyetheramine D series is used in conjunction with other curing agents, contributing flexibility to the finished product.
As for non-epoxy applications, IRO Polyetheramine D series finds use ineffective chain extender of polyurea RIM(Reaction Injection Molding), thermoplastic polyurethane adhesives, salts, and the fluids cutting and fire retardants.
Additionally, IRO Polyetheramine D series has the drain and oleophobic group on the structural backbone.It is a good emulsifier agent in the oil field.
IRO Polyetheramine D series has micro toxicity in oral administration; non-toxicity for skin absorption; weak irritation to skin, and strong irritation to eyes.
Please use a mask to protect the face when loading/unloading.
If it contacts 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 it contacts with the skin.
