Full Description
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:
| | Section |
