I looked it up online this time. It is indeed a moisture-cured polyurea product. Sorry for the confusion in my original post. It does come with a catalyst in a separate can. I guess with gloss moisture-cure polyurea products, the catalyst helps shorten the dry time considerably.

According to descriptions on various websites, this kind of coating is very hard, waterproof and can withstand much higher heat than oil based polyurethanes.
