A series of chemical modification of PVA (polyvinyl alcohol) resin

2022-08-03

Through a series of chemical modifications to PVA (polyvinyl alcohol) resin, the water resistance of PVA and the compactness of the arrangement of PVA molecules are improved, so that it is difficult for gas molecules to pass through the coating. At the same time, a high-barrier ore body is added to the coating solution to form a high-barrier barrier, which strongly and effectively inhibits the movement of the polymer, and further improves the barrier properties of the coating.

Features:

  ·High oxygen barrier

  ·No need to pre-apply primer

  ·Good printing performance

  ·Environmental protection, the ingredients are only carbon, oxygen, hydrogen, harmful gases after combustion
