Epoxy is usually used in making cartridge assembly in inkjet printing. Adequate cross-linking or curing is necessary to bring stable cartridge assembly. Tri and tetra functional amines are used in curing epoxies. DSC, RHEOMETRY and fracture tests were done epoxies with and without blends with butyl rubber liquid. In rheometry, experiments were done in a parallel plate rheometer ARES to analyze cross-linking of epoxy using different levels of tri and tetrafunctional amines. Elastic and viscous modulus were measured as function of time at a fixed shearing frequency. Reaction kinetic equation was set up, equilibrium modulus and cross-link density was calculated. This parameter was correlated to breakage of the cartridge assembly
