Description of ASTM-D4690 2012ASTM D4690 - 12Standard Specification for Urea-Formaldehyde Resin AdhesivesActive Standard ASTM D4690 | Developed by Subcommittee: D14.30 Book of Standards Volume: 15.06 ASTM D4690Abstract
This specification covers three types of urea-formaldehyde thermosetting resin adhesives suitable for use on wood, wood-based substrates, or plastic laminates. 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. Testing procedures are specified to differentiate between the physical and adhesive bonding properties of the many commercial urea-formaldehyde thermosetting resin and catalyst systems. The adhesive bonding properties are measured on maple block and birch plywood specimens, prepared and tested in accordance with prescribed methods. 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. Scope
1.1 This specification covers three types of urea-formaldehyde thermosetting resin adhesives suitable for use on wood, wood-based substrates, or plastic laminates. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only. 1.3 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. 1.4 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.
