- Coating Solution characterization
This information can be used to improve coating quality, develop novel products, improve productivity and reduce costs. The operating efficiency of all personnel process, R&D, Manufacturing, Engineering, can be significantly improved by utilizing the many technical technology resources that are available
An important consideration in locating the appropriate information is to recognize that the basic technology of the coating process is independent of the final function of the coated product. The underlying coating process technology is the same for all coated products. Any differences in the process for different products depends on the on the coating requirements, wet thickness, viscosity surface tension, line speed, number of of layers, thickness uniformity, quality level and drying requirements. The process selected is based on these variables and not the coated product function. Therefore; technology on defects, coating methods, drying methods, coater operation testing from a different product can be adapted to the current process.
There are several general categories of technical information that are available:
- Technical Societies
- Publications
- University Research Programs
- Trade Journals (such as Converting Quarterly)
- Patents
- Miscellaneous Sources
Specific sources for each category will be listed in the next paragraphs. Only identification information on each source is given because it provides the basic information about the source content and will determine if contains the information that is useful. All of these are available on-line and can be located using standard search engines.
Technical Societies
There are several technical societies that focus on the selected technical areas of the coating and drying process. They offer technical meetings, continuing education courses, publications Webinars and Blogs. The society titles indicate their technology focu
- Association of International Metallizers, Coaters and Laminators
- Technical Association of the Pulp and Paper Industry
- International Society Coating Science & Technology ISCST,
- The Society for Protective Coating SSPC
