I、General Description
The product is a kind of macromolecule modified polyvinyl acetate
aqueous emulsion copolymerized with optimal process , taking
PVA、EVA、VAC as its main monomers and with multiple-purpose addition
agent. It features with good mechanic, freeze thawing and delusion
of stable performance and excellent heat resistance, strong
adhesive capacity to all kinds of papers, less shrinkage cavities
and edge-exposing, superior fluidity. The product is widely used
for bonding tubes of paper, and non-toxic products, it is
especially suitable for gluing the tubes as the container of
leisure food.
