HoK SG100, ok to use as filler before 2k clear?

[Farrell]

In the past I would put on a coat of 2k clear, wait 1 or 2 days, sand it smooth and put on another layer of 2k clear. This has worked great but takes a lot of time and I have to mess with mixing up batchs of 2k.

Having transitioned over to HoK paints, I am wondering if it is alright to use their SG100 Intercoat Clear as my sanding layer of clear. I do not imagine having any problems, but rather than mess up a project I am hoping someone can chime in with their experiences. To clarify, I will still put a layer of 2k clear on as a final coat, I know that SG100 does not have UV protection.

Thanks,

yes you will be fine

[mmccoy555]

As already stated you will be fine. That's what the sg100 is intended for amist other things.

I am new to airbrushing and I have never used sg100 ,but an experienced artist told me that sg100 was just a glorified single pack laquer, Is there any truth in that or is he talking crap.

[tugg]

so you can use single pack laquer as intercoat,?? how long would you leave to cure

You could use it, I wouldn't myself...SG is just a basecoat, Yer stacking weak layers on weak layers..Best to keep them to a minimum..I won't add any more than I need to.

You say you put on a few layers of clear, then sand and do it again...Is this for the final clear, or are you adding more graphics over the sanded clear then clearing when done??

When I clear for the final time...I lay on 4 coats, wetsand and buff..done deal....Sometimes I need to put a Clear layer to protect artwork and add more on top..I use 2k for that..It's the same amount of work as it would be with SG, but much stronger.

just me though.

the reason i wouldnt use it is its tendancy to stay soft which can create wrinkling issue down the line or cracking and crazeing ,it wont expand or contract at the same rate as any two pack clear put over the top ,it therefore is not wise to mix those two different technologies in this way

Howdy Paul , If You wouldn,t mind Clarifying , as I,m allways confused about whats called Laquers on Yer side of the pond & what I,m used to around here from years ago . I,m not up on the newer products here , much less over there . Just seems some products are called different things depending on where You are .

It Might help Me not confusing others If & when I can help about what I know about the old acrylic laquers . if that makes sense . Thanks , CB

[ARTSPRAYJ4J]

its an ambigous term at best as in the UK we term clear coats as lacquer no matter what they are made of ,however for the most lacquers are usualy concidered as nitrocellulose or acrylic single pack

true lacquer comes from the Lac tree and its origins lay in Japan in all other contexts its just a generic term which can create some confusion

another example is jewelers rouge whos name has been adopted to include many fine polishes ,to be rouge it must be in fact as the name implies RED yet we see brown white green and just about every colour in the rainbow described as jewels rouge ,no self respecting jeweler would use anything but true rouge ,all the other are poor substitues and are sold off the back of this traditional name ,same as lacquer realy as true lac is still concidered the finest and clearest form of "clearcaot" and the most durable

europeans basicly made a cheap version of Lac and have been doing this ever since resulting in all the more modern two pack versions ,Birmingham England where i am from is well know for these cheap lacquered goods which like our city are known as Brummagem ,we where also noted for fake coinage of the same name ,our fake groats where found across the kingdom hehehe

thats why we are know as brummies

now if you werent confused before im sure you will be now LOL

sorry for the longwinded explanation but its realy the only one

NP Paul , I Apreciate You clearing it up . Interesting info & I can even understand it , lol . Thanks . CB

bud its only by vertue of talking to Yanks i catch myself refering to laqcuering as clearcoating ,most every sprayer i know will look at me a bit miffed when i do ,i dont know if its a UK thing but we lacquer a job we dont "shoot clear" or "clearcoat"

we define a specific lacquer by virtue of its technoligy ,if you think about it it makes the question a little easier than changing the name to suite the technoligy to us they would all be "clearcoats" of one description or other

ask me what lacquer im useing and i will tell you imediatly ie two pack urethane ,acrylic etc or single pack cellulose,acrylic etc

in the US there is a definate distinction between the two terms and i often get called out for saying i have lacquered a job by the yanks as i do when the oposite ocures over here

anyone learning from forums will have usualy picked up the American terminoligy and wont know what the hell Lacquer is anyway LOL
laqcuer to us would never include colours in the states it doese ,its just one of those language differences and it took me a while to realise what the yanks where talking about


Paul

[ABD]

I still have to ponder on it a bit when I see talks of "Laqs" from you guys over yonder ..lol.....Lot of us Yanks are imported English anyway...Hell the Amish over here call us "The English"...lol....Ya'd think we could stick with the same descriptions:D.....I've never sprayed Laqs...But Clear coat all the time..hahaa

I don't mean to bring the thread back on topic, but... ;)

If I top coated my work with SG100 and forgot to clear it, can I clear it later on without wrinkling, etc.? I painted some fiberglass stuff about six months ago, put on a layer of SG100 and promptly forgot about it. :( I don't think I would have any problems with putting some 2K clear over it, but throught I'd check with you guys. The 2K clear will be reduced with RU311, the same reducer that I use when painting.

Just sand and clean it before spraying yer Clear..You'll be fine.

[ARTSPRAYJ4J]

as above ,its delam that would be the issue and sanding overcomes that
