Standard Test Method for Tack-Free Time of Caulking Compounds and Sealants
ABSTRACT
This test method describes the determination of the tack-free time property of caulking compounds and sealants. The method is applicable to both gun and knife grades. Requirements for the apparatus including the cabinet or room, brass sheet, template, steel sheets, plastic strips (polyethylene strips), spatula, and knife blade are given. Methyl ethyl ketone, ethylene dichloride, or similar solvent shall be used. The test specimen shall be sampled from a previously unopened container and shall be thoroughly mixed before using. The method of preparation and conditioning of the test specimen, and the test procedure are detailed. No caulking compound or sealant shall adhere to the polyethylene strip in the test specimen.
SCOPE
1.1 This test method describes the determination of the tack-free time property of caulking compounds and sealants. This test method is applicable to both gun and knife grades.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
