Surface Modifications | Common Bond Failure Modes
Adhesion failure
When the adhesive delaminates from one of the material surfaces. Surface treatment is needed to correct this problem.
Cohesive failure
When the bulk strength of adhesive is far less than the material and adhesive strength. A different adhesive choice must be made to correct this problem.
Substrate failure
When the bulk strength of the material is far less than the adhesive and the adhesion strength. This type of failure typically indicates a successful treatment and adhesive choice.

Common Industry Applications
Medical
- Plasma-cleaning
- Devices including catheters, endoscopes, stents, intra-ocular lenses, etc. prior to the application of a specialty and/or lubricious coating, adhesive, or marking.
Optical
- Plasma-cleaning and/or photolysis treatments
- Materials including polycarbonate, glass, CR39, TrivexTM, PMMA, and urethane, for lenses, films, depositions, MOEMs.
Pharmaceutical
- Devices for drug delivery and storage
Biotechnology
- Plasma-cleaning, functionalization and silane deposition treatments
- Micro-arrays, micro-fluidics, MEMs, etc.
Aerospace, Automotive and Commercial Products
- Improve the adhesion of gaskets and other dissimilar materials, remove "tack" from silicon devices, and increase adhesion of elastomer material to metal, polymers and other elastomers
