Meaning and Purpose
4.1 The test method can be used to select the coating powder to gel at the specified temperature in the required time. This method is not useful for the determination of curing time.

ASTM D 4217-2017 “Gelatinization Time of Thermoset Powder Coatings”

Scope of
1.1 This test method determines the length of time required for a thermoset paint powder to gel on a polished metal surface at a specified temperature (e.g., 204°C (400°F)). The determination of gel time is a very simple method for characterizing and quality controlling coating powders. However, the gel time determined by this method is not directly related to the time of curing of paint powder in practical applications.

1.2 This standard is not intended to address all safety issues, 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.

1.3 This international Standard has been developed in accordance with the 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 of the World Trade Organization.
