Standard Test Method for Bubbling of One-Part, Elastomeric, Solvent-Release Type Sealants
SIGNIFICANCE AND USE
4.1 The type and amount of solvent used in these sealants can sometimes give rise to surface bubbling (blistering) problems. The substrate used, whether porous or nonporous, will also have an effect. Although bubbling is often caused by misapplication, this test method is useful in differentiating between a sealant that develops an acceptably smooth surface and one that may have bubbling tendencies.
SCOPE
1.1 This test method covers determination of the degree of bubble formation or surface blistering in one-part, elastomeric solvent-release type sealants when exposed to elevated temperatures.
1.2 The subcommittee with jurisdiction is not aware of any similar ISO standard.
1.3 The values stated in inch-pound units are to be regarded as standard. 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.

Overview
ASTM C712-22 is the internationally recognized standard test method for evaluating the bubbling (blistering) tendencies of one-part, elastomeric, solvent-release type sealants. This method is essential for manufacturers, installers, and quality assurance professionals in the building and construction industry, providing a consistent approach to assess surface bubbling when sealants are exposed to elevated temperatures. Bubbling or blistering can compromise both the functional and aesthetic qualities of sealant applications on various substrates, making this test critical for product development and application verification.
Key Topics
- Sealant Bubbling Assessment: The standard outlines a procedure to determine the degree of bubble formation or surface blistering of specific sealants after exposure to elevated temperatures.
- Significance of Solvent Content: It emphasizes that the type and amount of solvent in sealants, as well as the nature of the substrate (porous or nonporous), can influence bubbling behavior.
- Substrate Influence: The test method considers different substrates, which can accelerate or mitigate bubble development under heat, affecting sealant performance.
- Test Conditions and Reporting: ASTM C712-22 specifies standardized specimen preparation, heat exposure conditions, and reporting requirements for reproducibility and clarity.
- Safety and Compliance: Users of this standard are responsible for establishing appropriate safety, health, and environmental practices, and checking for any regulatory limitations.
Applications
ASTM C712-22 plays a pivotal role in the following practical applications:
- Quality Control for Manufacturers: Enables sealant producers to ensure their one-part, elastomeric, solvent-release type sealants meet industry expectations for surface smoothness and resistance to bubbling under heat.
- Product Comparison: Allows buyers and specifiers to compare different sealants’ performance under controlled conditions, supporting informed material selection.
- Problem Diagnosis: Helps builders and applicators identify if bubbling is due to product formulation or application issues, such as misapplication, improper storage, or unsuitable substrates.
- Specification Compliance: Ensures sealants used in construction projects comply with client, regulatory, or industry requirements regarding visual and performance standards.
- Research and Development: Supports the development of new sealant formulations by providing objective bubbling assessment methods during R&D phases.
Related Standards
For a comprehensive evaluation of sealants, ASTM C712-22 should be considered alongside other key ASTM standards:
- ASTM C717: Terminology of Building Seals and Sealants. Provides definitions of terms used throughout ASTM standards for building seals and sealants, including those in C712-22.
- ASTM C719: Standard Test Method for Adhesion and Cohesion of Elastomeric Joint Sealants Under Cyclic Movement. Focuses on the movement capabilities and durability of elastomeric sealants.
- No ISO Equivalent: At the time of publication, there is no ISO standard directly equivalent to ASTM C712-22, making it the primary international reference for this type of bubbling evaluation.
Keywords: ASTM C712-22, sealant bubbling, blistering test method, elastomeric sealants, solvent-release sealants, building and construction standards, quality control, substrate effect, surface smoothness, ASTM sealant testing.
By following the procedures and recommendations in ASTM C712-22, stakeholders in the construction and sealant manufacturing industries can achieve more reliable, longer-lasting, and visually acceptable sealant joints, reducing costly rework and enhancing overall project quality.
