Meeting Title: 

Sealant Adhesion and Compatibility Study


Aceh Community Room
Mercy Corps, 45 SW Ankeny St

Sharon Libby, Walsh Construction


This presentation will explain how this sealant adhesion and compatibility study was conceived and executed and will also provide conclusions about the observed reactions between many different substrates and sealants. This study was executed to determine the varying levels of adhesion between commonly specified sealants and substrates (including weather resistive barriers, self adhered membranes, liquid applied membranes and cladding components including brick, fiber cement cladding and various window materials. Similarly, observed compatibility issues will be discussed and the cause of the incompatibility explained in order to better inform designers about posssible adverse reactions between materials.
