Anotace

This specification covers polyvinyl acetate or polyvinyl acetate copolymer resin emulsion adhesives suitable for use on wood, wood-based substrates, or plastic laminates. This does not cover the group of polyvinyl-based adhesives suitable for bonding flexible films. Adhesives are classified on the basis of water resistance at three performance levels, namely wet-use (Type 1), intermediate use (Type 2), and dry-use (Type 3). Adhesives shall conform to test requirements as performed under the following exposure conditions and treatments: dry shear at specified temperatures; two-cycle boil; 48-hour soak; humidity exposure; freeze-thaw stability; and storage life. Materials shall also adhere to physical properties such as density, nonvolatile matter, and pH.
