Hot Melt Pressure Sensitive Archive Adhesives

Test method standards for automotive and aerospace adhesives address test methods for a variety of adhesives, including metal bonding adhesives, hot melt pressure sensitive archive adhesives, their working properties, and other properties. Particular attention is paid to the testing of the strength and durability of the adhesives. These standards are related to the different physical properties of hot melt pressure adhesives under normal working conditions.

ASTM D1994-07(2015)

Standard Test Method for Determination of Acid Numbers of Hot-Melt Adhesives

1.1 This test method covers the determination of acid numbers of hot-melt adhesives. 1.2 This test method is applicable for hot-melt and hot-melt/acid systems that are soluble under the conditions described. The hot melt must also give light- or medium-colored solutions when dissolved. If this is not the case another method must be used. 1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 1.4 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. Specific caution statements are given in 7.1 and 7.2 .

ASTM D2979-16

Standard Test Method for Pressure-Sensitive Tack of Adhesives Using an Inverted Probe Machine

1.1 This test method covers measurement of the pressure-sensitive tack of adhesives. This test method is applicable to those adhesives which form a bond of measurable strength rapidly upon contact with another surface and which can be removed from that surface cleanly, that is, without leaving a residue visible to the eye. For such adhesives, tack may be measured as the force required to separate an adhesive and the adherend at the interface shortly after they have been brought into contact under a defined load of known duration at a specified temperature. 1.2 The values stated in SI 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. 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.

ASTM D3111-19

Standard Practice for Flexibility Determination of Hot-Melt Adhesives by Mandrel Bend Test

1.1 This practice covers the determination of the flexibility of a hot-melt adhesive in sheet form under specific test conditions. This is a working practice. Its results are useful for comparing adhesives, not for absolute characterization of adhesives. 1.2 The values stated in SI 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. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D4497-10(2018)

Standard Test Method for Determining the Open Time of Hot Melt Adhesives (Manual Method)

1.1 This test method covers the manual determination of the open-time range of hot-melt adhesives under the stated conditions. 1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units in parentheses are provided for information only. 1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D4498-07(2015)

Standard Test Method for Heat-Fail Temperature in Shear of Hot Melt Adhesives

1.1 This test method is intended to determine the temperature at which specimens bonded with hot melt adhesive delaminate under static load in shear. 1.2 The values stated in SI 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. 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.

ASTM D4499-07(2015)

Standard Test Method for Heat Stability of Hot-Melt Adhesives

1.1 This test method covers the evaluation of hot-melt adhesives with respect to the change in properties that occurs while the adhesive is aged in the molten state during hot-melt application. Melt properties monitored are viscosity, color, skin formation, and phase separation. 1.2 The values stated in SI units are to be regarded as the standard. 1.3 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.

ASTM D6195-03(2019)

Standard Test Methods for Loop Tack

1.1 These test methods cover the determination of properties of a pressure-sensitive adhesive. These test methods are applicable to those adhesives that form a bond of measurable strength rapidly upon contact with another surface. Tack force may be measured as the force required to separate the adhesive from the adherend at the interface shortly after they have been brought into contact under a load equal only to the weight of the pressure-sensitive article (for example, tape, label, sticker, etc.) on a 1 in. 2 contact area. 1.2 The following test methods are included: 1.2.1 Test Method A (using Tensile Tester), and 1.2.2 Test Method B (using Loop Tack Tester). 1.3 The values stated in inch-pound units are to be regarded as the standard because the industry standard width for pressure-sensitive tape is 1 inch. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
