Hi guys wobder if any1 can help every time I mix my resin flexcoat and then apply to whippings I get blush on the surface now I thought this was because the temperature with it being winter but I still get it in the summer even though it is dry and warm both my resins get warmed to aid mixing any help would be appreciated

Amine blush is caused by a particular combination of humidity and CO2. Generally it will rectify itself by leaving the rod in a very warm room, or even in direct sunlight, for a day or two.

If this won't do the trick, you may be looking at something else entirely.

Stan,
You aren't doing anything to the wraps after wrapping are you?
i.e. you aren't doing something like wiping the wraps with DNA or another solvent are you?

Be safe

The finish will have a slight hase to it if not mixed well
Are you mixing long enough it should look clear after it is mixed

Yes lads I mix tge resin well and do nothing with the threads it even happens on the decals its doing my head in bought a humidity meter but still get the blush

Stan,
Since nothing else seems to pop out, have you tried a new batch of guide wrap coating?

I wouldn't think that there is anything wrong with the finish, but your results might point that way.

Be safe

Stan,
What is the temperature and humidity of the room where you apply finish?
When you warm the finish, how do you warm it?

If you haven't tried it before, about 5 seconds in a microwave does a great job of warming the finish.

As Mr. Kirkman said in his post - normally blush is the result of humidity in the finish application area. If you are in a warm area, do you have an air conditioner that you could use in the finish room, to insure that the area stays low in humidity?

Be safe

Yes tried a new batch even a different brand I started getting it last year in the winter but the fact we have had a great dry warm summer and still getting it is crazy tried warming resin in microwave also in warm water so they were the same temp to no avail

Thanks rodger interesting read

I take it you are using a High Build finish

I will almost bet you a Light Finish may just work better for you
Same trouble I used to have with painting a car in hot muggy weather I would thin it and slow down the drying time and it would work well
A light finish is thinner and has a little longer set time letting any mosture evaporate
I use flex coat but the UV new stuff High build -- But i thin it

Will try that bill I will thin it with a bit acetone thanks or by a light coat regards stan

Stan

Just don't over do it and thin too much
Try several ways on a piece of scrap blank I have used lacquer thinner - Mid Temp -- now I tend to like a
urethane reducer - medium

I still do not know if your place is Hot and Muggy or if it is cool or very cold
I have done finish in cool yet not really COLD temps
When hot like 90 with a lot of humidity I turn on the air

Thanks bill and all the other lads for your help will try and let you no really appreciate it regards stan

Stan

I also put my finish on a 70 RPM turner It holds the finsh on as it levels And gives me nice edges at the ends because it turns faster

Thanks I have no problems with edges etc nice and feathered into the blank just this blush but I will not be beat thanks

Good luck

Ya got to figure out this problum

I am going to assume that you do not exhale on the finish to break bubbles?

...............

No blowing on the bubbles in the resin the blush appears when I put the resin on the whippings even when I check the mix prior it is not visible

So it doesn't blush in the cup?

Out of curiosity, what type thread are you using?
