| Abstract: | In the present report, thermal analysis (TMDSC, DMA, TG, stress-strain analysis), nano-indentation and AFM morphological characterization
of cross-linkable latexes, prepared with either a pre-coalescence cross-linker (1,3-butylene glycol dimethacrylate) or post-coalescence
cross-linker (adipic dihydrazide) at various levels of cross-linking, were done. The study assesses the effect of type and
level of cross-linking on the film formation process through the evolution of mechanical properties and latex morphology.
In addition, the final fundamental thermal and mechanical properties, specific end-use properties and latex morphology resulting
from the film formation process are reported. |
