Meaning and use

5.1 Paint formulation designers can use this practice to determine whether a given paint has the ability to form a film at low temperatures. This practice can be used to help determine the level of coalescence solvent needed to form a good film. Test method D3793 compares the porosity of a film stretched at room temperature with another film stretched and cured at low temperatures.

5.2 This practice does not provide absolute information, but merely a ranking of the selected series of paints.

5.3 This practice can provide a pass-fail scenario if known acceptable and unacceptable coatings are included in the test.

ASTM D7306-17 Standard Practice for Testing Low Temperature Film Formation of Latex Paints by Visual Observation

Step 1: Scope

1.1 This practice specifies a laboratory procedure for evaluating the ability of latex paints to form uniform films at low temperatures without apparent defects.

1.2 Values expressed in SI units shall be considered standard. The values given in parentheses are for reference only.

1.3 This standard is not intended to address all safety concerns, if any, associated with its use. It is the responsibility of users of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.

1.4 This international standard is based on internationally recognized standardization principles established in the “Decision on Principles for the Development of International Standards, Guidelines and Recommendations” issued by the Committee on Technical Barriers to Trade (TBT) of the World Trade Organization.
