UV Resin Warning

Just wanted to pass along a minor disaster I had today.  I get my UV Cure Resin from two different sources depending on convenience.  We will call them Supplier A  and Supplier B.  Nothing but good things to say about both suppliers as I’ve used both for quite a long time.

 

Supplier A ships their UV resin in a black UV Resistant platic jug like this and I have never had a problem.  The resin pours nicely and I even refill these sometimes with the resin I get from supplier B:

 

Supplier B ships their UV Cure resin in metal gallon containers similar to the one pictured below except for one small problem…the spout part is made of a non-UV resistant plastic with a pull out inner seal.

 

 

So here is what happened.  Today I glassed a board and I finished off one of the black jugs of resin part way into the hot coat.  I grabbed an unopened gallon of resin in the steel can and pulled the seal.  To my surprise there was another seal inside.  Perplexed for a second, I realized what had happened.  At some point between point a and point b the jug of resin had seen some sunlight.  Perhaps walking to the car or in the car on the drive home.  Otherwise the resin was stored in a dark place where I’ve stored UV resin for the past decade without incident.  This created a stalagtite of sorts of cured resin inside the jug and all sorts of little boogers in the rest of the resin.  In all I’d say a pint of resin was cured inside the can.  As it was the only gallon of resin on hand I made due.  I’ll have some extra sanding to do needless to say.  My plan is to strain the rest of this gallon so I can finish off this board and I suppose I’ll use the rest of it for ding repair.

Here is a pic of some of what was inside my gallon of resin:

 

Moral of the story, if you buy UV Cure resin look for the places that put it in the widely available Black UV Resistant F-Style contaners they can buy from U-Line or any other supplier of shipping containers.  If Supplier B reads this, I hope you change shipping containers.

Rant over.

 

You can always buy regular resin and add the uv additive I do this to be on the safe side

Like Jcyr said, use normal resin and ad some UV additive.

I use SunCure UVC 2000 and it’s a hell of a additive.

Normally I prepare around 1.5L of  UV resin and store it in a whisky metal box and then inside a wooden vine box 

LOL I don’t use to drink alcohol, my girlfriend’s father gives me a lot of things to store tools/resin/pigments. He is also my “pigments dealer” hahahaha



Mako isn’t asking for help/advice.

His post was meant as a head’s-up and warning.

Thanks for that Mako.

Bingo.  That was the point…that and hoping the supplier reads this and makes changes to UV resistant containers.

Mako - hopefully they do see it. 

Where I get my resin it comes in the metal containers BUT the spout is also metal. Seems like the container you get would cost more as well. 

Not a fan of the metal containers at all.  I live on an island surrounded by salt water and the metal cans start to rust in my shed.  I reuse the black plastic ones.

I’d be willing to bet that I’m not the only one to have gotten resin from this supplier and had this happen.  You expose one of those containers to sun light and you’ve got problems.   Guessing they use the can they use because it has a good seal for shipping purposes so leakage isn’t a problem.  The supplier with the black plastic containers heat seals the entire resin container in a clear plastic wrapper so it can’t leak.

 

Why don’t you contact supplier B and tell them of the problem.  If they have any integrity they may just send you another can of resin gratis.  It won’t hurt to try.

I’m making use of it.  I did this gloss coat out of the bad resin yesterday.  I took a scrap of 4oz cloth and some rubber bands around a resin bucket and filtered the crystals and clumps out of the resin.
