Epoxy Separating

Has anyone had this happen? This is the first time I have used a pigment additive in my epoxy and also the first time using a liquid mold release called Frekote 700nc. I was attempting to apply my first coat of epoxy to my plug as I have done on my first plug with good results. As soon as I started to brush it on, it started to separate. I was able to wipe it off very easly before it cured. However, I am wondering if it could have been the pigment additive.

This is only the second mold that I have done. The first one worked fine other than my plug construction, and plug surface quality was poor. So, this time, I did a lot research on construction techniques and proper plug surface requirements. After reading about different mold release types, I choose to use a liquid type. From what I have read, you can achieve a better molded part surface finish.

Any input would be great.

Thanks,

Lee Adams

Hi Lee,

No problem at all. I appreciate that the split of the forum into an Easy Composites support section (staffed by myself and colleagues) and then a general forum (not staffed by ourselves) is a little confusing. We are of course very much hear to help you with any queries you have on your Easy Composites products and if there's a bit of overlap with products from other manufacturers then we'll try to help there too but it is a little harder.
