an unexpected property of reninfusion 8604

Don’t let fully cured reninfusion come in contact with water. It’s nearly water soluble. Even humid environments coming in direct contact with it causes the loss of surface gloss. This is for 8604 but likely apply for some of the other products in this family.

Which is great considering I wanted to use waterjet trimming.

Very good information to share! Thank you from more than one on here I bet! :eek:

That is very, very strange. Have you verified this with several batches? Confirmed that it was all mixed properly?
The people infusing marine stuff must be having fun with water soluable resin.

I did it with multiple batches. With a kit about 6 months old. The resin is properly measured and mixed. The parts are made through compressing in rencast molds. The parts come out with the gloss of the mold, just breathing on them causes the weave to show. Obviously these are without gel coats and clear. I then dropped cured neat resin leftovers and cured composite parts into water to soak. After a few hours both were noticeably softened.
