MECHANISMS OF ADHESION

ANALYSIS OF THE ADHESION PROBLEMS INDICATES THAT INSUFFICIENT MOLECULAR CONTACT AT THE ADHESIVE-SUBSTRATE INTERFACE IS THE MAJOR CAUSE FOR POOR ADHESIVE PERFORMANCE. THIS CONCLUSION IS BASED ON SEVERAL THEORETICAL CONSIDERATIONS AND IS CORROBORATED BY A NUMBER OF INDEPENDENT EXPERIMENTAL DATA. THE CONDITIONS UTILIZED FOR PREPARING ADHESIVE BONDS MAY PLAY A MAJOR ROLE IN SETTING THE PERFORMANCE. THE SURFACE ENERGIES AND RHEOLOGICAL BEHAVIOR OF THE ADHESIVE ARE IMPORTANT IN DETERMINING THE RATE OF WETTING. WETTING AND BOND FORMATION MAY BE SYNONYMOUS FOR THE MAJORITY OF CASES. THE MOLECULAR CONFIGURATIONS AND CONFORMATIONS OF POLYMERIC ADHESIVES MAY INFLUENCE THE ADHESIVE PERFORMANCE IN A NUMBER OF WAYS, AND MAY PLAY A SIGNIFICANT ROLE IN ESTABLISHING WHETHER FAILURE OCCURS ADHESIVELY AT THE INTERFACE OR THROUGH COHESIVE FAILURE OF THE ADHESIVE ITSELF. SEVERAL CONTROVERSIAL HYPOTHESES ARE EXAMINED CRITICALLY. /AUTHOR/ REFERENCES' ADVANCES IN CHEM., HUNTSBERGER, J.R., SERIES NO 43, PP 180-188, 1964 J POLYMER SCI., J.R.
