Paint coatings continued alkyd resins

Alkyd resin along with solvent has been successfully encapsulated inside UF shell by In situ encapsulation technique. The SEM analysis shows that microcapsules were comprised of a thin continuous shell wall and a rough exterior shell wall. The FTIR spectra of original and soxhlet extracted resin proves the encapsulation of alkyd resin inside the shell. Moreover DSC and TGA analysis shows that the microcapsules contain both resin-solvent mixture as core and UF as shell material. These microcapsules incorporated in paints or coatings release the healing material when scratched which in turn heals the scratches and cracks.
