Need advise on carbon fiber wrap

Hello guys. we try to do stuff with carbon but do not get as one company Robson design say they put some kind of special epoxy to protect surface from scratches and chemical things for 2 years? how that can be? anyone have a clue what they can put on top?

Also why after i lay epoxy on top and next day when it dry surface not dry but like on goose like wax you clean it and ok? maybe humidity?

Thanks a lot

  1. Marketing BS.

  2. Do a search on “blushing” which will get you further. Humidity plays a role indeed.

yes but what they do polish epoxy or sand? do not get as they get hard surface and they say can not damaged by chemicals or mechanically as they say special mix they use

It can be a chemical resistant epoxy coating.

Can be polished with any automotive polish. One of my customers uses copper polish. (and buys it by the barrel…)

I’m pretty sure their parts are not chemical resistant. Everything is chemical resistant to a point. Some finishes take seconds, some finishes take minutes, some take longer. They just market their stuff the way the rest of us do haha.

so you think guys they use epoxy and simply polish with wax that is why surface so hard?

Even if thats what they do don’t do it. If there is no clear coat, they have a product that won’t last.

Apply your resin weather its epoxy or a solvant based resin, get the shape you want, and then clear coat it with a 2k automotive clear coat. I can’t think of a better way to do it.

It might take a little more work, but its worth it and your product will last.

Robson design looks good, but I’ve herd their stuff dont last. Maybe this is why…

Also, its eaiser to polish a clear coated part instead of an epoxy part. IMO.

i wrote to skype can we chat?
also where you heard about that for robson design?

What is the good epoxy for doing wrap? I seen a lot of print through especially parts been baked under the sun.

For carbon parts in the sun (wrapped or not) you need an epoxy with a very high Tg. Depending on the area you live, expect a desired Tg of 80-100 degrees C. About always you will need to postcure the epoxy before it reaches this high Tg.
Check the datasheet of your epoxy for the Tg, and get something else if it does not meet your needs.

Alternatively, many people use vinylester for this reason, which usually has a higher Tg without postcure.

this epoxy i see better hold on surface the polyster and not eat laquer like polyster
