View Full Version : question on how to extend life of AB casting fluid
May 29th, 2011, 03:47 AM
Hi, I was trying to get some casting fluid to try on things, bit i found out they get expired easily due to moisture and humidity, and i live in hong kong, yea, imagine that... but i recall some tutorials i saw on magazines, and i remember seeing the artist having a much smaller bottle to contain the fluid, so make me wonder if there are any ways to extend the life of those fluids?? can i keep them in a fridge??
would be grateful for any help, cause they normally sold in 2kg and they ain't cheap...

You could get a Dry Purging Agent. It's an inert gas in a spray can that is heavier than air. Before you fully put the lid back on your container, you spray this gas into the container and it displaces the atmospheric air which in turn removes the moisture that causes the resin/rtv to go bad.
However, you'll have to check on if you have a local supplier because I think these are considered hazardous materials and shipping overseas (from the US) might be a problem.

Yes, I agree....I use a product called " Burp" and it is a gas that is shot through a tube into the cans and then you put on the lid as fast as you can....the refridgerator may help, but be careful....you don't want to take a chance with contaminating your food, health reasons...
It's best to plan a body of pours so you can use up as much as possible in a short time, because like you said, It ain't cheap....I have lost all mine because I didn't use it up soon enough..

We keep ours in a dedicated fridge. it also keeps the resin from "kicking" as quickly. We pour it into one gallon containers and use those til they're gone, then refill them. keeps you from having to open the main buckets too much. If you live over there, can't you just get the recasters to do it for you cheap? LOL!
