2k lacquer?

[Chipper]

Chaps have a look at the pic of the product, it says 2k on the can...

Quick search on "HB Body autoclear 496" shows it described as 2k all over. Also available as normal cans to mix.

Could it be out of date, hardener has a shelf life.

Or maybe - guess - being a can it has a higher thinners content than you'd mix for a gun. And so laying on wet coats has woke up the basecoats, making for the tackiness

I checked the can earlier and it does not mention anywhere on it "Isocyanate", so dont think it is 2 pack, but why state it on the tin!

I will get in touch with HB bodyshop tomorrow to see what it is..

I applied 10 minutes of heat to each wheel earlier (says 10 minutes at 23 degrees) on can, and now they are down my parents cellar, leave them there until next weekend when Im having the tyres fitted...hopefully some improvement in curing by then........

If it says 2k it is paint+hardener, must have the widget inside.

The sheet for the 'nomal' paint (non-aero) says to use 722 hardener, and that has isocyanates, described as such on the company's website http://www.hbbody.com

I've just been in touch with the HB Body company technical advisor, and he said it does state 2k on the tin, but it is more like a 1k.....(false adertising??)

Advised it will go off, due to the amount of coats I put on, it will take slightly longer...it is used in the automotive industry quite alot, and is hard and protective when sets....

time will tell...

Ive used this stuff as well on a bonnet.
Bonnet looks terrible now but tbh i think that is more to do with trying to spray a large area with rattle cans!
My door mirror caps turned out well as i was able to get it painted on good and thick.

Did you have any issues with drying time? Take long to completrly dry?

How hard/protective is it when cured?

Mike, to be honest on the bonnet i dont think it ever properly cured!
On the wing mirrors it seemed to cure well and has resisted a few wing mirror to wing mirror contacts with only scuff marks present which could be polished out.

The wing mirrors were dried in the airing cupboard so i assume this is why they cured well.

Edit; i wouldnt say it was an overly hard lacquer though seems to have like a slight rubbery characteristic, especially on the bonnet.

hi just wondering how a 2k laquer in a can would work as it needs ativator to harden and if that was in the can it would set in the the can wouldnt it ???
and it should have flash times if they are out slightly in the wrong temperature then it will stay soft , and that 1k laquer isnt any good i waited 9 days for some to cure and buffed it and ripped the laquer off

as mentioned elsewhere there are 2k cans that have 2 compartments , you push a button underneath to release the harder
