Significance and Use
These test methods are intended to compile as well as provide screening tests in evaluating clear and pigmented lacquers as used in different coating operations.
Each coating system may contain from a simple one coat operation to a multicoat finishing system.
The substrates may be varied, ferrous and non ferrous, plastic or wood which can affect the performance of a given coating system.
Substrate cleaning, chemically or physically, is an essential and critical aspect to the performance of the coating system.
Results from the various tests are not necessarily all useful in evaluating the performance of the different types of coating systems used on the many varied substrates.
1.1 These test methods cover procedures for testing lacquers and lacquer coatings. The test methods included are listed in Table 1.
Note 1 - In accordance with Terminology D 16, a lacquer is defined as a coating composition that is based on synthetic thermoplastic filmforming material dissolved in organic solvent(s) and that dries primarily by solvent evaporation. Typical lacquers include those based on nitrocellulose, other cellulose derivatives, vinyl resins, acrylic resins, etc.
Note 2 - Lacquers may be applied under such diverse conditions, to so many different surfaces, and their dried films may be subjected to so many kinds of wear and exposure that it is not possible to assure desired performance from a single selection of test methods and numerical results therefrom. Those skilled in lacquer technology may find partial assurance of obtaining desired qualities in various types of lacquers through careful selection of the methods covered herein and intelligent interpretation of results therefrom.
Note 3 - It is intended ultimately to remove all experimental procedures from Test Methods D 333 and to establish them as a guide to the selection of test methods for lacquer and perhaps to interpretation of results therefrom. Temporarily there remain in Test Methods D 333 a few tests that are too short or otherwise presently unsuitable for establishment under separate ASTM designations.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
