Evaluation of Various Generic Types of Building Sealants Against ASTM C-920, Standard Specification for Elastomeric Joint Sealants

Source

A number of sealant manufacturers suggest that although they supply primers for their sealants, in many cases the primers may not be necessary. They usually suggest running a test on the substrates the sealants are to be used with to determine if the primers are needed. This paper will discuss the results of testing several commercially available polysulfide, silicone and polyurethane sealants against ASTM C-920, Standard Specification For Elastomeric Joint Sealants. Mortar, plate glass and anodized aluminum were used as the substrates. Where manufacturers supplied primers, the sealant was tested with and without their primer. Where the manufacturer did not recommend primers, testing was only done without a primer.
