2k, iso, acrylic, waterbased, celly - a bit confused

[rsb123]

Hi there -

I'm getting myself into a confused state and I'm hoping you can clear it all up for me please.

Question 1 - Does all 2K clear coat contain Isocyanates?

Question 2 - What is the acrylic paint in the rattle cans from halfords, is it waterbased or 2K solvent?

Question 3 - What are the different types of clear coat and what are their characteristics, for example, solvent based, 2K Acrylic, Waterbased, 2K Iso?

Question 4 - Is there such a thing as waterbased 2k clear coat? How do I tell which is a solvent clear coat and which is waterbased?

Sorry for so many questions!

By the way, I guess I've got more money than brains at the mo - I've got a new Air fed mask, and a devilbiss triple stage filter to remove water and oil etc., a hefty petrol compressor, and a paint extraction system in my home made garage booth. So I can spray using 2K iso without health risks. But I just need to understand it all first.

Many thanks,
Jim

I have a go at helping but I am not an expert I can be corrected.

Question 1 - Does all 2K clear coat contain Isocyanates?
All the 2K contains Isocyanates, so as the waterbased.

Question 2 - What is the acrylic paint in the rattle cans from halfords, is it waterbased or 2K solvent?
Halford can do rattle can with celly, I am not sure about acrylic.

If you are new in the painting like me apparently the cellulose painting is the way to go for beginner and it is easier for the safety.
That said I am not in no way an expert.

2k is "zwei komponent" i.e. paint+hardener, plus thinners. Mostly the activator does contain isocyanates. (House of Kolor do a non-iso 2k epoxy but take a deep breath looking at HoK prices).

The rattle cans off the shelf are 1k acrylic (solvent based).
Pretty sure the paint mixed to order is celly though.

Clears: 2k is best. 1k is not as durable as 2k. Waterbased clear is an 'intercoat' not a final clear.

4 - waterbased doesn't use an activator. Usually you go to a shop and ask for what you want, so you'd know, or it'd be marked.

That said there is a non-iso 2k system:

the guy that told me about it said his son is using it, but no reports of what it's like.

There's always celly, or synth enamel as used on Landies.

I used water based metallic for the first time a few months back and was very impressed with it, It wasn't by choice was just the paint code for the car was for water based, I then used a 1K laquer to finish it off

I was that impressed that I will be spraying my mini project in the same paint, i've only used celly and synthetic before and didn't massively rate either, wouldn't spray with 2K at home personally

Question 1 - Does all 2K clear coat contain Isocyanates YES
Question 2 - What is the acrylic paint in the rattle cans from halfords, is it waterbased or 2K solvent SOLVENTWhat are the different types of clear coat and what are their characteristics, for example, solvent based, 2K Acrylic, Waterbased, 2K SOLVENT BASE ADD THINNER, 2K ACRYLIC ADD HARDNER AND IN SOME CASES THINNER (isocyanate) They do a clear coat in water base ,were it goes on milky then dries clear .We dont use it in the body shop never really took of.As for water base .You add 10% or 15% of water to your base paint .NOT ordinary water .
