I had a test piece of plywood coated with Repti-Shield in which I used no catalyst. (repti-Shield is a moisture-cure coating.) Finally after 3 weeks and being left out in 2 days of rain, it cured completely. Odorless and like a thin layer of plastic was melted onto the wood.
I beat on it with a rock, and did the same on a piece of decent melamine. The melamine, while pretty tough, did break through (the coating). The Repti-Shield coating had nicks, cuts and was dented (the wood dented) but did not peel off. And another dab of the product seals it back up.
