This specification covers the general requirements for liquid paint dryers used in paints, varnishes, enamels, and similar organic coatings. The liquid paint dryers that are solutions of six classes of metallic salts, should conform to quantitative requirements such as metal concentration, nonvolative matter content, specific gravity, color, and viscosity. Each type of drier should be a mobile liquid free of sediment and suspended matter and should be stable and miscible with oil.
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.
Significance and Use
4.1 This specification covers the general requirements for liquid paint driers used in paints, varnishes, enamels, and similar organic coatings.
4.2 The values listed should be considered as general guides to the character of the products, rather than reproducible constants.
1.1 This specification covers liquids for use in paints, varnishes, enamels, and similar organic coatings and are solutions of metallic salts of:
1.1.1 Class A—2-Ethyl hexanoic acids in petroleum spirits.
1.1.2 Class B—Naphthenic acids in petroleum spirits.
1.1.3 Class C—Neodecanoic acids in petroleum spirits.
1.1.4 Class D—Tall oil fatty acids in petroleum spirits.
1.1.5 Class E—Any of the above acids or acid blends, but containing additives that make the liquid drier water dispersible. Some other driers may also contain complexing agents.
1.1.6 Class F—Other acids and acid blends unidentified by their producers.
1.2 The following applies to all specified limits in this standard; for purposes of determining conformance with this standard, an observed value or a calculated value shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit in accordance with the rounding-off method of Practice E29.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 For specific hazard information and guidance, see the supplier's Material Safety Data Sheets for materials listed in this specification.
