Physical Properties and Testing Bond separation at the interface between the adhesive and the substrate, leaving no appreciable residue.
Rupture of an adhesive bond such that the separation appears to be at the adhesive-adherend interface.
This type of failure occurs when the adhesion of the sealant to the substrate to which it was applied fails. This is the worst type of failure for a sealant to experience. This is because repairing it usually means that all of the sealant must be removed from the joint, and the joint must be thoroughly cleaned and then resealed. (See " Cohesive Failure")
The failure at the bond line between a substrate and an adhesive; the adhesive separating entirely from the substrate.
Condition that exists when bonding agent pulls loose from a surface.
Adhesive failure indicated by the material's failing (pulling loose) at the surface of the substrate. Similar to "scotch" tape peeling off a plastic substrate.
A rupture of adhesive bond that appears to be a separation at the adhesive-adherend interface.
Separation of two bonded surfaces that occurs within the bonding material. The adhesive separates entirely from the substrate. Note: Adhesive failure occurs when the adhesive strength of a bonding material is greater than it's cohesive strength. (more about failure mechanisms)
Failure of a compound by pulling away from the surface from which it is in contact (see cohesive failure).
Loss of bond of a coating or sealant from the surface to which it is applied.
Loss of adhesion between the adhesive and substrate. The adhesive pulls cleanly away from the substrate.
failure of the bond between the sealant, adhesive, or coating and substrate surface
Failure resulting from insufficient bond between the adhesive and one or both sustrates. Adhesive strips away from substrates.
