Applicable Base Polymer Properties

Waterborne polyvinyl acetate adhesives have the same base latex resin that is used in wood glues. These adhesives provide a low to medium performance, inexpensive adhesive that dries to a relatively rigid material. A typical formulation consists of polyvinyl acetate latex, filler, plasticizer (for improved flexibility), and water. Since these adhesives set by evaporation, they shrink on drying more than 100% solids adhesives.

Typical Formulation Ingredients

Ingredient

Parts by weight

Polyvinyl acetate emulsion (e.g., Gelva TS-70, Solutia)

Dibutyl phthalate plasticizer

Toluene sulfonamide formaldehyde (e.g., Santolite MS-80, Monsanto)

Processing

Resulting Properties

A typical waterborne polyvinyl acetate adhesive formulation is shown above. This is the type of product that is commonly used for bonding paper and paperboard. This particular adhesive has found acceptance in the bookbinding industry.
Without any plasticizer PVAc adhesives will become hard and brittle on aging. The addition of a plasticizer such as dibutyl phthalate will soften the PVAc polymer and eliminate embrittlement.
