The present invention discloses a novel film coating composition of polyvinyl alcohol (PVA) in combination with sugar, and a plasticizer or a combination of plasticizers resulting in a composition which is non tacky and easily dispersible in water at high solids content. The coating compositions help in achieving higher spray rates, disperse in less solvent i.e water, and helps in reduction of coating process time. Further the resultant film which when coated onto substrates exhibits good adhesion and provides smooth surface to substrates.

A vulcanizing agent is added during the processing of a polymer, and can form a crosslinking structure network in the polymer, thereby improving the mechanical properties of the material. Furthermore, the crosslinking agent can also de-crosslink the polymer material at a high temperature, and after being cooled, same can be crosslinked again to produce a network structure, thus endowing the polymer material with thermoplasticity for repeated processing.
