"PolyAziridine Global is dedicated to the aziridine crosslinker market and to be the repository of this technology. We were founded because this very important area of technology and the existing users were ignored.
Our products are, from any technical perspective, among the most effective cross linkers for water based formulations that must be cured at room temperatures. This is particularly true concerning acrylics and PUD based products, for example but not only, when carboxylic acid reactions are involved.

PolyAziridine Global pledges to address this by offering not just a complete line of polyfunctional aziridine cross-linkers but also to provide the technical support so important to their successful use. We offer equivalent replacements for products such as XAMA® 7 which have been discontinued.

Polyfunctional aziridines are very versatile molecules with wide-ranging usage in coatings and adhesive applications. These cross-linkers are used to improve both physical and chemical properties for both aqueous and non-aqueous coatings. Many applications involve their use as adhesives modifiers."

PolyAziridine Global PZE-1000 is an ethylene imine based tri-functional polyaziridine that is used as a cross-linker for both aqueous and non-aqueous coatings, inks, and adhesives to promote both physical and chemical properties. With the highest level of functionality at 3.3, it yields the highest level of cross-link density of polyfunctional aziridines. The aziridine end groups can react with active hydrogen as found on carboxyl groups of acrylic emulsions or polyurethane dispersions. PZE-1000 also has a hydroxyl group, which allows it to dispersion readily into aqueous systems. PZE-1000 is added at levels of 1% to 3% to finished formulated coatings, inks, or adhesives. It is added slowly and under good agitation. After mixing, an aqueous system with a pH of 9.0-9.5 will typically have a pot life of 18-36 hours. This time will be reduced when the pH is lower.

PolyAziridine Global PZBI-25 is a cross linker agent that improves bonding and cohesive strength of resins and binders, resulting in films with better resistances, particularly scratch resistance, abrasion, hydrolysis and general chemical resistances. As a blocked isocyanate, the blocking end groups can react with active hydrogen as found on carboxyl groups of acrylic emulsions or polyurethane dispersions. An interesting feature is that no CO2 is released.
