Overview of Aliphatic Isocyanates capped with Aziridine from Menadiona PZU-1000, Spainsummary:

PZU-1000 Aziridine terminated Aliphatic Isocyanate is a new product developed to meet market demand. It is an aziridine terminated aliphatic isocyanate with outstanding resistance to yellowing and flexibility as a medium temperature crosslinking agent.

PZU-1000 aziridine terminated aliphatic isocyanates can be widely used as crosslinking agents in water-based and oil-based textile printing and leather finishing industries, which can improve the physical and chemical properties of products.

The finished white powder of PZU-1000 aziridine capped aliphatic isocyanate is usually added in an amount of 5 ‰ -2%. Before use, it is dispersed with water or relevant solvents and uniformly added to the formulation system. Dispersed liquid (in water or solvent) should be added to the system as soon as possible within 2-3 days for use. The cross-linking process is related to pH and temperature.

Application of Menadiona PZU-1000 Aziridine terminated Aliphatic Isocyanate from Spain:

    Generally speaking, PZU-1000 aziridine terminated aliphatic isocyanates are best dispersed with water at room temperature before being added to the system. The stability after addition is affected by the pH and storage temperature of the system. A high pH system and lower storage temperature are beneficial for improving storage stability until rapid cross-linking reaction occurs with the product after the ring opening temperature.

Aziridine crosslinking agent PZU-1000 is an aliphatic isocyanate terminated with aziridine, which is applied in industrial fields such as textiles and printing and dyeing. It can improve washing resistance, enhance color fastness, provide a softer hand feel, be environmentally friendly, and resist yellowing in leather coatings. The addition amount is 1% -2%, and the addition amount is 1% -2%.
