(Test Method)Standard Test Method for Nonvolatile Content of Liquid Phenol, Resorcinol, and Melamine Adhesives
Standard Test Method for Nonvolatile Content of Liquid Phenol, Resorcinol, and Melamine Adhesives
ABSTRACT
This test method covers the determination of nonvolatile content or total solids of liquid phenol, resorcinol, and melamine adhesives with or without hardener added and containing high-boiling and low-boiling volatile organic solvents or water, or both. The equipments to be used in the test shall include a petri dish, circulating-air oven, desiccator, and analytical balance. In determining the nonvolatile content of the liquid adhesives without hardener, the procedure shall include oven-drying, cooling in a desiccator, and weighing of adhesive and quartz sand . The percent nonvolatile content shall be calculated based on the amount remaining. On the other hand, the procedure for the liquid adhesives with hardener shall include oven-drying, cooling in a desiccator, and weighing of mixed adhesives. Also, the percent nonvolatile content shall be calculated based on the amount remaining.
SCOPE
1.1 This test method covers the determination of nonvolatile content or total solids of liquid phenol, resorcinol, and melamine adhesives with or without hardener (Note 1) added and containing high-boiling and low-boiling volatile organic solvents or water, or both.
Note 1—Some low molecular weight materials in the adhesive may be lost if hardener is not used. When a hardener is used, it must be mixed in accordance with the manufacturer's instructions.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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. For specific precautions, see 5.2.
