if you want to know when the Catalin Corp. acquired the Bakelite formulas. They made up their own brand name for Bakelite. They called their Bakelite "Catalin". Of course they tinkered with it, but it's still Bakelite. Bakelite is phenol formaldehyde. Catalin is a brand name for phenol formaldehyde. It's simple.

A phenol formaldehyde by any other name smells phenolic. I hope Shakespeare's heirs don't trouble me for appropriating his work.
