Краткое введение:
HENSAMINE 7088 is a water-soluble modified amine curing agent designed for waterborne epoxy emulsions and liquid epoxy resins. Suitable for primers, intermediate coats, and high-gloss topcoats under ambient curing, it delivers high film gloss, moderate pot life, high hardness, excellent scratch resistance, and good chemical resistance[cite: 9, 10].

Свойства хранилища:
Store in tightly closed original containers in a cool, ventilated, and dry area away from fire sources. Shelf life is at least 12 months under ambient sealed conditions. Note that prolonged storage may cause the color to darken, which is a normal phenomenon.
Меры предосторожности при обращении:
Use appropriate personal protective equipment (PPE) such as protective gloves and safety glasses. Avoid contact with skin, eyes, and clothing. Flush immediately with water in case of contact and seek medical attention if necessary.
Упаковка:
Supplied in 20 kg and 200 kg net iron drums.
