Subject:
crosslinker...
Response To:
how it cures ()

...is this the same concept (generally) as the cross linker additive in water based finishes? To extend the length of molecules so that they can tangle more completely resulting in higher hardness?

(I've sprayed target with and without crosslinker, and then sanded or buffed them to a gloss. The difference is incredible with the crosslinker).

There must be some cross/commonality with this and the high build finishes with isocyanates in them - well, there is or isn't, not must - but a wild guess of mine. I haven't used those again since painting a car hood with them and having no clue how toxic they are. The result was a finish that created overspray that was very difficult to even scrape off of glass.
