Expert in Formulating, Applying, Curing, and Troubleshooting Coatings for Ophthalmic Lenses, as well as Other Transparent or Polymeric Articles

Chemistry With over 25 years of industrial experience, Expert , a degreed chemist, is an authority on the materials, equipment, and processing aspects of coating ophthalmic lenses, as well as other substrates.

Coatings Expert is extremely knowledgeable in the chemistry of formulation, surface preparation, application, and cure of coatings, especially, but not exclusively, those coatings that are used on ophthalmic lenses.

Practical Manufacturing Experience He has personally been involved in the establishment of commercial cleaning, coating, and curing processes at various locations worldwide. He is very knowledgeable of the materials, equipment, and processes that are or can be used in coating all types of ophthalmic lenses, including all lens geometries, whether cast or injection molded.

Ophthalmic Lens Coatings, Siloxane Coatings, Waterborne Coatings With regard to coatings, Expert has invented and successfully used in various manufacturing facilities, a wide variety of coatings, a number of which have been patented, proving that he is both practical as well as sound in theory. Examples include coatings for adhesion promotion, scratch resistance, dye absorption, photochromic activity, temporary protection, and other special purposes. These coatings range from the organometallic siloxane variety to the purely organic types such as acrylics and polyesters. His expertise includes waterborne, solventborne, and solvent free systems.

Polymer Formulation, Polymer Synthesis, Coating Formulation Expert has formulated as well as synthesized various types of polymers for a wide variety coatings, inks, and adhesives. These polymers include addition polymers such as acrylics as well as condensation polymers such as alkyds, polyesters, and polyurethanes. Expert has also formulated commercially successful products from those polymers. In addition to coatings, he has also formulated other commercially successful products, including cleaning solutions, inks, and surreptitious marking materials for use in such things as security features, or to assist in inventory control, among other purposes.

Curing Techniques Expert has extensive expertise with coatings that are cured using heat as well as coatings that are cured with various forms of radiation, whether ultraviolet light, visible light, or radiant heat, including both acrylate and oxirane functional systems.

Cleaning, Surface Preparation, Coating Application With regard to application equipment and processes, his knowledge encompasses dip as well as spin application methods. Furthermore, he has designed processes for cleaning, surface preparation, and drying substrates prior to the subsequent application of a coating, often in a clean room environment.

Analytical Chemistry, Defect Analysis, Trouble Shooting, Expert possesses great troubleshooting skills, having done defect analysis and process improvement for many years. He has extensively used FTIR as well as FTIR microscopy in conjunction with a variety of IR sampling techniques for the purposes of analyzing coating defects, quality control, kinetic studies, and comparing competitive materials that were obtained by legitimate means. He is experienced with optical microscopy, UV-Vis, GC, and other instrumentation that is commonly used for analysis or other types o

Selected Consulting Examples:
  • With the use of carefully designed experimentation, a complete reformulation was conducted of a radiation curable coating that was intended for use on ophthalmic lenses and other optical devices. The new coating product provides superior mar resisatnce, adhesion, durability, solution stability, and cost, as compared to all other radiation curable coatings that are presently used in this industry. This has been confirmed by an independent testing laboratory.
  • FTIR microscopy was used to identify the chemical composition of numerous microscopic particle defects that were ocurring in a precision coating operation. FTIR was then used to scan the suspected source of the particles. This gave an exact match, providing proof positive as to the source of the contaminant, and led directly to the elimination of a longstanding, expensive problem such that the yield was dramatically increased.
  • Used optical microscopy to quickly but correctly determine the root cause of a sporadically recurring defect in a laminated film product that had plagued the client for several years in spite of their best efforts and the best efforts of others to resolve the issue.
  • Determined the cause of instability in a coating formulation that was resulting in various coating defects, reduced shelf life, and, ultimately, premature gelation. Proposed practical modifications to both the formula and the process that was used to prepare the organometallic coating solution. The combination of modifications completely and permanently eliminated the problem.
  • One particular client was in jeopardy of losing a $17MM acount due to the inability of their customer to use expert's client's product in a manufacturing process. It appeared that the customer's manufacturing process was resulting in damage to the coating that was on the product that was being purchased from his client. A tactful meeting with his client along with their customer at the customer's facility allowed for the determination of the defect and the cause. This was confirmed via relatively simple testing and was corrected, resulting in the retention of the business. A letter of appreciation from the client is on file.

International Experience:
Years   Country / Region   Summary
2001 to 2001   Indonesia/West Java/Bandung   Established a startup, high volume coating operation in a class 100 clean room environment. The critical cleaning processes employed various techniques, including ultrasonics, high pressure spray, aqueous detergents, organic solvents, and others. Both thermally cured and radiation cured coatings are employed in this manufacturing operation. In spite of adverse circumstances, all of the deadlines were met and the project was deemed a success. Subsequent defect analysis, troubleshooting, and process refinements have increased the yield to beyond the original expectations. These yield levels have since been maintained. This facility is still in operation today.
2000 to 2000   France/Il-de-France/Paris   Installed a new spin coating operation for opthalmic lenses after specifying the equipment that was to be used for surface preparation, cleaning, curing, and testing. The project was successful.
1998 to 2000   Mexico/Baja California/El Sauzal   Established an entirely new precision cleaning, coating, and curing operation. Qualified and installed new coating solutions as well as various equipment. This equipment included several curing units, and multiple HEPA filtered units for the dip application of the organometalic coatings. The operation was a complete success, meeting capacity and yield goals shortly after startup. Also installed a testing laboratory, complete with inspection equipment, an optical microscope, a gas chromatograph, and other testing equipment.
