Thread: Isocyanates???!!!

hey all out there in ab land hope all is good. i had the chance to go to a automotive paint supply open house in beaumont. they had free beer, crawfish, and many vendors including Iwata, 3m , mirka. by the way if yall never heard of mirka they have some really awsome scuff pads ! and all they vendors gave out all kindsa cool goodies . it was so awsome guys i learned alot and drank alot lol any way im preparing to do some PRACTICE four wheeler fenders they were free and it gives me a chance to break into solvents with no fear of ruining good plastics. and im wanting to know what the hell exactly an isocyanate is . i know they are the things that make the paint get hard . thats the only lamens terms i got from the iwata guy . he was smart lol and was way over my head. is an isocyanate a molecule that is located in (hardener reducers) or (hardeners) and do you reduce the paint and catalyse it or just one of the other? i talk to much and ask too much lol but dangit i need some clarification on this lol . and for the record im using hok . and do i need to invest in a DA sander or is good ole hand sanding good enough ? ok ok im gonna quit typing now

ok i just read the other post that was up that had the isocyanate discussion in it . and i think i just need a good ole fashioned country boy explanation lol

Isocyanines are found in activator (harder).

You don’t what to airbrush with paint that requires activator in it. KK, SG, BC, PBC HOK colors require no activator.

As Lee has already said for most people airbrushing it might be best to establish a relationship with a auto body shop and let them do you clear coating as that requires activator.

oh so its the clearing process that has to use hardener !!! i feel so silly ! i was under the impression that the paints i wanted to use (HOK) required hardener. so if i got this straight there is clears that require hardeners which contain the lil nastys and clears that dont right?

"i was under the impression that the paints i wanted to use (HOK) required hardener."

Some HOK colors do require it those I listed do not, check with your local HOK retailer.

All good clears require an activator yes
