Aziridine Content, meq/g :5.4-6.6
Density (g/ml ):1.05-1.09
Viscosity, cp :100-300
2) Application
C-100 is a propylene imine tri-functional polyaziridine that is used in both aqueous and non-aqueous coatings, inks, and 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.It had gained rapid growth in polyurethane dispersion and acrylic emulsion formulations for applications such as film coating, wood finishes, leather finishes, overprint varnishes, and inks.
