Wood Coatings
Wood coatings often are slow to dry and highly abrasive.
Polyaziridine resins work to cross-link acrylic emulsions and polyurethane dispersions to utilize nucleophilic carboxy groups.
Along with a faster cure time and enhanced performance of low volatile organic compound (VOC) formulations, Polyaziridine products are also easily mixed and dispersed into coatings.

In addition, many long-term effects are also realized as a result:
-Improved water and chemical resistance
-Increased resistance to black heal marking
-Better abrasion resistance
-Enhanced color and clarity

Protective Films:
Protective films for paints, windows or windshields have to withstand a lot of wear and tear due to heavy traffic and exposure to different types of light sources.
Along with a faster cure time, the addition of Polyaziridine also modifies adhesion characteristics of the films.

Printing Inks:

The negatively charged outer surfaces of cells are attracted to dishes coated in Polyaziridine, facilitating stronger attachments between the cells and the plate.

*Transfection reagent:
Polyaziridine was the second polymeric transfection agent discovered, after poly-L-lysine.
Polyaziridine condenses DNA into positively charged particles, which bind to anionic cell surface residues and are brought into the cell via endocytosis.
Once inside the cell, protonation of the amines results in an influx of counter-ions and a lowering of the osmotic potential.
Osmotic swelling results and bursts the vesicle releasing the polymer-DNA complex (polyplex) into the cytoplasm.
If the polyplex unpacks then the DNA is free to diffuse to the nucleus.

*Permeabilization of gram negative bacteria:
Polyaziridine is also an effective permeabilizer of the outer membrane of Gram-negative bacteria
