Topic: Bad idea to powder coat these?

[ncstatecamp]

Can I powdercoating these engine mount bars or Is the fit to tight?

[70CB750]

I would not do it.

[lrutt]

no way you will get those back in if PC. Just paint the heads and ends. Apply grease to the center sections to aid in assembly and keep them from rusting. Or you could zinc plate them if you buy one of those kits I guess.

[mono]

yeah, clean/lightly grease them.   lol.  no one sees them anyways. 

and +1 on them never going back in with PC on them.

[seanbarney41]

...plus, one of them performs the crucial task of grounding the frame and engine...

[ncstatecamp]

Ok off the rack then! Thanks all!

guys who do PCing can mask parts off just like painters can.  So perhaps just have the heads done.  You will then need some fairly gentle scheme for knocking them in place so the plastic does not get dinged up.

What plastic?

Did not know that thanks

Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as household appliances, aluminium extrusions, and automobile and bicycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods.

I guess it could be a plastic or a polymer what ever that is.

Wiki
A polymer is a large molecule (macromolecule) composed of repeating structural units. These sub-units are typically connected by covalent chemical bonds. Although the term polymer is sometimes taken to refer to plastics, it actually encompasses a large class of compounds comprising both natural and synthetic materials with a wide variety of properties.

Because of the extraordinary range of properties of polymeric materials,[2] they play an essential and ubiquitous role in everyday life.[3] This role ranges from familiar synthetic plastics and elastomers to natural biopolymers such as nucleic acids and proteins that are essential for life.

Dang now I can't live without powder coat.

All that aside, what socket size do you think you would have to use if you did put-cot the bolt head?

[trueblue]

It would probably all chip off when you try to tighten it, PC is horribly brittle stuff, I used a catalysed acrylic paint on my frame and fixtures, it is as hard as PC but not as brittle.

[millerza]

are you wanting to PC for corrosion reasons or just looks(bolt heads)?

I think most PC dries to 2-3mil so go on that i guess. But anyway, I had my aluminum fork tubes gun coated with NIC industries flat black because it is "clamp-able". Might look into that. I believe it goes on super thin like an anodize and is resilient as well. Even after clamping, removal new seals and re-clamping, not cracks or chips in the finish. Also, PURPLE POWER and SUPERCLEAN don't affect it so it must be strong.

When I make parts to fit over powdercoat, I allow 20-30 though for the powder thickness.
