Hi,
I am using Alumilite White with microballoons to make a casting that is buoyant. I'm using a fairly high concentration of microballoons at 10% by weight of resin (probably around 75% by volume). All the products I'm using are brand new.
I'm seeing a small amount of expansion while the resin mix cures, maybe 10% or so. Is this normal for resin with microballoons or am I getting moisture contamination? I need to keep the weight of the castings very consistent and it is challenging with this expansion.
I did some research and I'm seeing conflicting opinions on this. Some say it's normal when using the microballoons and others say it shouldn't expand.
Thanks!
