Claims17
A liquid adhesive concentrate, comprising:
- a polyvinyl alcohol-stabilized vinyl acetate-ethylene copolymer dispersion in a range from about 75% to about 90% by weight of the liquid adhesive concentrate,
- a dry polymer in a range from about 10% to about 18% by weight of the liquid adhesive concentrate,
- a surfactant in a range from about 0.3% to about 1.2% by weight of the liquid adhesive concentrate,
- a defoamer in a range from about 0.3% to about 0.5% by weight of the liquid adhesive concentrate,
- a biocide in a range from about 0.1% to about 1.5% by weight of the liquid adhesive concentrate, and
- a dispersant in a range from about 0.3% to about 1.2% by weight of the liquid adhesive concentrate.
