I brought this up a week or two ago. The Rutland/Union rep was in today, and we told him about the problem. He said it's most likely an imbalance in the pH. He has used the MaxOpaque to mix into Plasticharge a lot, and has had no issues. When they took a look at the gallon we had, they determined it was old, hence the imbalance in the pH. They guarantee their shelf life on non activated base to be a year, so they are sending a replacement. NOT a pigment problem as we had previously surmised; I thought it would be good to share. Always fun to learn something new.
