Has anybody had any experience with Phenolic resin?
I need to make some race car brake ducts which will get very hot.
I think you can use high temp Epoxy resin like from BJB Ent. in Tustin.
I never have used Phenolic resin and I hear the dust is very hazardist…
Friends, I have some Aircraft folding tables that are wrapped in Carbon Fiber , but over time the resin, clear coating has turned milky , I will try to carefully sand some layers off, and try to get it down to where it is clear again. Trying to find out what Clear coating i can use again that is fire resistant, and has UV protection. I understand that Phenolic resin is used for Aircraft interiors , but would need a coating that i can sand smooth and buff to a clear finish. Your help would be greatly appreciated.

Phenolic is a b**** to work with, and is hazardous before cure. I’d use a high temp epoxy with a tg of around 350 or so. Unless you’re dealing with carbon/carbon brakes, your rotors shouldn’t be getting more than about 900F peak and 650 average. Your brake ducts should not get hotter than your calipers, which have to remain below ~250-300F or you’ll boil brake fluid and get soft fade (pedal goes to floor as if there is air in the system).
We have worked with Phenolic for over 2 decades and as above, Phenolic isn’t the easiest of resins to work with. Good ventilation is a must. You also need to take in to account required oven curing, and then post curing. Finishing tasks are labour intensive. The so called surface improver paste (applied as a gel coat) gives no real void free surface once it is hit with a DA. Plenty of other systems available that would suit your requirement
