We're trying to sell him on white silicone, but he is not comfortable with the leaching that might occur over time. This is not a glazing application. I only have seen black EPDM. Does anyone know if it's available in custom colors?

I ran into this a few years ago. Have you tried Santoprene - it comes in colors, including white.

What is the application? I agree that Santoprene is a good option for gaskets.

Silicone gaskets show better test results than Santoprene . We're using the gaskets between GFRC ceiling panels.

Make sure they won't bleed into the concrete like the sealants can do.
