Resulting Properties
Waterborne Vinyl Chloride Heat Seal Coating Adhesive (B) for aluminum, paper, vinyl, and polyester substrates can
be formulated with AW-875. For vinyl substrates, a formulation consisting simply
of AW-875 and a coalescent is often satisfactory. For surfaces such as aluminum or
polyester, the addition of a plasticizer or the alloying of AW-875 with a low Tg acrylic,
such as UCAR Latex 173, greatly improves bond strength. The adhesive is coated on
the substrate, dried, and later sealed with appropriate equipment, such as hot bar-type
or dielectric sealers for vinyl substrates.
