Sealant Compatibility

Testing Method:

ASTM C794 Standard Test Method for Adhesion-in-Peel of Elastomeric Joint Sealants. This test method covers a laboratory procedure for determining the strength and characteristics of the peel properties of a cured-in-place elastomeric joint sealant--single or multicomponent--for use in building construction.

Test material is adhered to a solid smooth substrate. Adhesive/sealant is applied to the substrate as described in ASTM C798. After the adhesive/sealant has cured a peel test at 180 degrees is performed. The results reported here are not considered a substitute for project specific field or laboratory adhesion testing. Project-specific adhesion testing is always recommended.
