HVLP For Automotive Refinishing
If you were to advise a painter who has to work with high-solids, low-VOC coatings and/or water-based paints and primers on how to select an HVLP, what would you suggest he look for? What selection criteria should he use?

I am a manufacturing engineer responsible for product development for a supplier of fasteners and fastener tools. The big issue right now is finding a coating that can hold up to 1,000 hr of salt spray. We’ve had the greatest amount of success with zinc nickel plating (400 hr in salt spray). At this point, we are interested in any coating technology, including plating technologies, organic technologies, or even a plating/organic hybrid technology.

What failure mechanism could likely trigger this? What are the material conditions that might be contributing to this?
Read MorePrep for Painting Over Powder
Is sanding the only method to get paint to adhere to powder coat, or can a good quality primer be used in lieu of sanding (provided there is no slip agent in the powder)? Are there specific types of primer and paint that you would recommend for this type of application?
Read MoreFinishing System Durability
While the specific paint chemistry can clearly have dramatic impact on the durability of the finished component, the use of effective surface cleaning and conversion coating practices may actually have an even greater impact. If end users and coatings applicators are looking to improve paint adhesion and corrosion resistance, it is critical to consider the surface preparation of the component.

I am a finishing engineer in a sheet metal fabricating factory. At a recent staff meeting, our boss asked us to look into reducing every energy-using operation. We have lowered the temperature of our iron phosphate pretreatment system. Can we do the same with the zinc phosphate pretreatment?

am the senior engineering manager in charge of product development execution. The problem comes about after a translucent paint is applied over a chrome-plated polycarbonate/ABS plastic substrate. I’m assuming that the chrome plating must be prepared (cleaned or etched) before paint application, but I need some recommendations to forward to the factory.
