A practical guide for ensuring a defect-free coating and drying
process
For professionals in the coating and drying industry, the world
is a demanding place. New, technically complex products such as
fuel cell membranes, thin film batteries, solar cells, and RFID
chips require coatings of extreme precision. With the bar raised so
high, understanding how to troubleshoot and eliminate defects on a
coating line is an essential skill for all personnel.
Coating and Drying Defects, Second Edition provides
manufacturing and quality control personnel, equipment operators
and supervisors, and plant engineers and scientists with the full
complement of proven tools and techniques for detecting, defining,
and eliminating coating defects and operating problems, and for
ensuring that they do not recur.
Updating the valuable contents of the first edition, this
practical Second Edition:
* Describes all major processes for coating and drying of
continuous film on sheets or webs
* Covers technologies that have been recently developed to
prevent defect formation and improve operating procedures
* Provides a rational framework within which to assess and
analyze virtually any defect that may arise
* Offers step-by-step guidelines for conducting every phase of
the troubleshooting process, including defect prevention
Going beyond simply describing a disparate set of troubleshooting
techniques, this unique guide arms readers with a systematic,
nonmathematical methodology encompassing the entire coating
operation, becoming an indispensable resource for manufacturing and
quality-control personnel as well as plant engineers, polymer
scientists, surface scientists, organic chemists, and coating
scientists.
