Dip Painting

Post by johnpenn74 » Sat Jan 27, 2018 11:54 pm

Does anyone out there have any experience dip painting.

I work on lines at work that do this with decent results. But manually in the shop is another story.

Suggestions?

Sounds like it would use a lot of paint. How big of parts are you talking?

JP: If you're doing dip coat or flow-coating at work, you're probably aware of the control parameters for a decent job. When I was a service tech for powder applications, we also had a liquid dip line, and later, an e-coat line. As Shild mentions, quite a bit of paint is needed to cover the parts plus there needs to be viscosity (flow) criteria met i.e. time through a Zahn cup, plus sufficient pigmentation. Big issues for us were drip control - too thin and the paint runs off too quickly leaving very thin paint on the upper surfaces. Too much solvent left a finish that looked like thin shellac. We used butyl cellusol for the carrier (water solube - almost). If you're going to use aromatics for the solvent, there are quite a few additional issues to control. In that case, you're better off going to spray instead of dip. Pretty hard to beat a nice spray acrylic in both looks and durability. Just my 2 cents...

The amount of paint in the pool would be a killer on anything bigger than a paint can. My brother does lots of powder coating with a regular kitchen oven from a garage sale. The results are very very good, far better than with a spray bomb.
