Standard Specification for Urea-Formaldehyde Resin Adhesives
 N D4690

Annotation

This specification covers three types of ureaformaldehyde thermosetting resin adhesives suitable for use on wood, wood-based substrates, or plastic laminates.

The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.

The requirements for the adhesive are based on tests of physical properties including viscosity, density, nonvolatile content, pH, insoluble matter, amylaceous matter, mixing properties, working life, and on strength properties, including dry shear strength in lumber-type joints, dry and wet shear strength in plywood-type joints, and all strength tests at the end of the storage life certified by the manufacturer.

The following safety hazards caveat pertains only to the test method portion, Sections 8 through 11, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
