Pumping Up Paint Productivity

Technology advances make robotic systems more cost-effective

1 May 2008

As you know, stripping and recoating is very costly in terms of time and labor. We are now applying a new baking enamel coating that is very durable. We tried touch-up and recoating by spot repair and total recoating with a durable air-dry paint, but we can’t get the touch-up paint to adhere to the damaged parts. Is recoating products a common problem? What can we do about it?

SPRAY BOOTH SELECTION

We are in the process of setting up a painting system for our products. Our application is spray painting of large and medium-sized castings. I would be obliged if you could advise me on which type of booth is better for my application.

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?

Adhesion Failure as Time Goes By

What failure mechanism could likely trigger this? What are the material conditions that might be contributing to this?

Primer Getting Thick

I am the manager of finishing operations in our plant. My paint line foreman tells me that the two-component primer we are using is getting thicker by the minute. Because the pot life was long enough, we had been mixing up a five-gallon batch of primer every day and applying it using siphon-feed spray guns on our products. What can we do?

Prep 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?

Finishing 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.
