Aliphatic Secondary Amine

E-90 is a low-viscosity aliphatic secondary diamine chain extender. Its reactive group is a slightly less active secondary amino group, which makes the chain extender have a suitable reaction speed and is more convenient to operate. It can be used alone or mixed with other amine/alcohol chain extenders to prepare aromatic/aliphatic polyurethane urea and polyurea products, such as RIM polyurethane, cast polyurethane elastomer, polyurethane sealing materials, coatings, adhesives, Spray polyurethane urea, etc. Polyurethane products prepared based on E-90 and aliphatic diisocyanate have excellent weather resistance.

Save

Store sealed in a cool, dry place. The color will become darker if stored for too long or in a light environment, which generally does not affect the reactivity.

Shelf life is 2 years. If the storage exceeds the shelf life, it can still be used after passing the inspection of the main application indicators.
