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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers polyvinyl acetate or polyvinyl acetate copolymer resin emulsion adhesives suitable for use on wood, wood-based substrates, or plastic laminates. It does not cover the group of polyvinyl-based adhesives which are suitable for bonding flexible films.
1.2 The adhesives are classified at three performance levels in accordance with water-resistance as shown in Table 1 and Table 2. See Section 5 for a description of the expected exposure conditions for each class of adhesive. See Table X1.1 for a classification of typical end products that are manufactured using adhesives at the three performance levels covered by this specification.
1.3 The following index is provided as a guide to the test methods portion of this specification:
