Profile: PolyAziridine LLC deals with aziridine crosslinkers. Our polyfunctional aziridines are versatile molecules used in coatings and adhesive applications. our products include PZ-28-polyfunctional aziridine and PZ-33-polyfunctional aziridine. Our PZ-28 is a propylene imine tri-functional polyaziridine which is used as a cross-linker for both aqueous and non-aqueous coatings, adhesives to promote both physical and chemical properties. The aziridine end groups react with active hydrogen as found on carboxyl groups of acrylic emulsions or polyurethane dispersions. Our PZ-33 is an ethylene imine which is used as a crosslinker for both aqueous & non-aqueous coatings, adhesives to promote both physical and chemical properties. The aziridine end groups can react with active hydrogen as found on carboxyl groups of acrylic emulsions or polyurethane dispersions.
