Q:
What new technologies are influencing coating services?
60 answers
Answers:
That depends on products and industries. In coating industry, I'm of the opinion that less environmental impact technology will sooner or later dominate the markets. Needless to say, cost effectiveness is one of the major concerns when replacement will be considered.
~Charles Hsu, General Management, Hsin-chu, Taiwan
Coating via inkjet process for textiles for deposition of nano-based coatings. Coating and drying of substrates using ultrasonic spray nozzle arrays for textiles conserving water and lower temperatures required for drying. Green coating technologies.

I cannot think of any other than doing a recreation of a historic structure after PPG did paint chip analysis on a mid 1800s residential property in W. PA on the PA canal and found that it was originally a Victorian "Painted Lady." It turned out awesome.

Q:
Do you know of any disastrous mistakes that occurred due to faulty or incompetent practices of coating services?
27 answers
Answers:
Well, it was more funny than disastrous, but it did result in a dramatic delay of a project, cost overruns, and performance penalties. An application of coal tar epoxy was to be applied to both the OD and ID of some Steel Line Pipe for an unusual Petro-Chemical project. The company that did it had no prior experience with coal tar epoxy or Tubular Goods. The OD was sprayed at non-controlled environmental conditions resulting in a horrendously ugly finish and the ID was actually applied with old kitchen mops. Removal of this application and reapplying by a competent company took weeks.
~Don C, Quality Control, Pittsburgh, PA
Recently one valve major has specified in his spec that Nickel Electroplating of Thickness 280 microns on a cast iron body. This is technically not possible. Even if we do this, the coating will peel off. This will make disastrous results if the Ni chips peel off and go into the control valve system.
~Ram Rajasekharan, Managing Partner - GE Process, Chennai, India
Many disastrous mistakes occur due to incompetent management. Our company's had a few fires in our painting lines caused by mistakes of judgment for maintenance required. No one can guarantee our system and/or equipment is zero defect, frequent service and visual inspection of noise, smell, wrong air stream...etc., might be the signs of impending disaster. One of our painting lines requires weekly maintenance for exhaust ducts of painting spray booth. In our holidays of Chinese Lunar New Years, due to the operators not on duty, management was forced by supply pressure delayed this job for a couple of days in weekend, which caused a fire in the plant. Not only our supply cause trouble, we lost orders from customers, too.

FeaturesTop

Q:
What would your design or feature "wish list" be for this service's capabilities?
44 answers
Answers:
A more simpler method of surface preparation, a one coat system that would include sealing the concrete surface (including blow holes & pinholes) and provide a flexible protective coating.
~Sean O'M, General Management, Birr, County Offaly, Ireland
1. Fast Curing under 6 hours. 2. One Coat system (Too much time between coats). 3. Extended recoat times. 4. Ease of application, spray instead of roller or brush.
~Santino Chami, Managing Director, Port of Spain, Trinidad, Trinidad and Tobago
Understanding that a perfect finish and a paint spec will never, ever work along side each other, with out extra cost. Refinishing is and art form, and not to be mistaken as a fixed budget.

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of coating services?
35 answers
Answers:
Please, above all, use the proper technical terms and not the vernacular. Do an analysis of the needs and wants before you proceed with requirements and specifications. Always use the applicable standard. Audit your vendor, make sure a Quality Program is in effect, applicators are trained, equipment is maintained properly and is proper for the job, demand proper control & storage of coatings, and ensure the proper HS&E programs are being used.
~Don C, Quality Control, Pittsburgh, PA
When the coater quotes the cost of a complete job, be sure to ask questions about surface preparation of the substrate prior to coating and what guarantees they provide regarding adhesion to same. Inadequate surface prep is the primary cause of premature coating failure. Just because a substrate looks clean, does not mean it is.
~Lawrence L., Research & Development, West Chester, PA
Every product has merits and demerits. Determine first the harm if coating is NOT done, then think, what could still go wrong even if coating is done. Take judgment whether you can afford any of these two in long term losses and short term losses, and then decide what should be coated, how much should be coated.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using coating services?
35 answers
Answers:
Ideally, select a coating service supplier that is capable of providing all aspects of the service "in house". If they have to out source certain aspects of the service (i.e. surface prep), problems arise more frequently.
~Lawrence L., Research & Development, West Chester, PA
Always choose the most suitable coating for the project Always prepare the surface correctly Always apply the product in the right environment ( temperature, humidity,moisture) Allow correct curing times
~Sean O'M, General Management, Birr, County Offaly, Ireland
Always ask for application methods, and supervised by supplier expert. Please do not go by just tall claims by anybody. Use your own judgment based on your process parameters.
