5.2.2.1 Technical data sheets (TDS) and Test Data

A product-specific TDS is a technical document containing the product description and some basic facts about the product, uncured and cured characteristics of the adhesive, general information on surface preparation and recommended application methods. The TDS will also provide product-specific technical information, test data regarding the performance of cured adhesives on common substrates and environmental resistance data. The American Society for Testing and Materials (ASTM) standards or International Organization for Standardization (ISO) test methods associated with the test data are commonly provided. The data published on the TDS is gathered using production batches to ensure it is as applicable as possible to real-world applications.

When trying to determine suitable adhesives and sealants, a product TDS is a great resource to gain an understanding of the product’s benefits and limitations; typically, these will be listed as hardness, shear strength, elongation at break, chemical resistance and temperature resistance. Data relating to adhesive performance when cured has been measured under specified conditions (such as temperature and humidity), which are typically listed on the TDS.
