The SWR Institute Pre-Cured Sealant Program was established to validate the published test results of the various pre-cured sealant products on the market. The intent of the program is to provide specifiers and end-users of pre-cured sealant products an unbiased method to judge whether pre-cured sealant products will perform at the levels of the manufacturer's published data sheet for that particular product.

Performance Properties Profile

Validation of the SWR Institute Performance Properties Profile shall include the following tests:

►C 1523 Standard Test Method for Determining Modulus, Tear and Adhesion Properties of Pre-cured Elastomeric Joint Sealants. Test must be performed to validate the greatest joint movement capability and tear propagation properties claimed on the Manufacturer’s data sheet.
►D 412 Standard Test Methods for Vulcanized Rubber and Thermoplastic Elastomers-Tension. Test must be performed to validate the ultimate elongation at break as claimed on the manufacturers data sheet.

Please note: All ASTM tests performed shall be the latest or current edition. All tests performed shall NOT be modified in any way. Sealant color for testing shall be selected from manufacturer's standard color chart.

Validation shall remain in effect for five years from the date of the validation testing. In the event the pre-cured sealant product is re-formulated by the manufacturer, the product must be re-tested and re- validated. Upon expiration of the validated product, it must be re-submitted for testing even if no changes have been made to the product.
