Review: Great product. - Great product and great for thinning epoxy primer. If you are brushing or rolling epoxy primer then use this thinner.
Review: Pretty much eliminates air bubbles in epoxy resin - Also, it cuts the amount of needed resin by at least a third if not in half. I think a lot of epoxy resin producers make the substance way too thick on purpose so that you have to use twice as much. Still, the biggest advantage is that it pretty much eliminates air bubbles. Only point to note is that it increases cure time by quite a bit, almost doubles it. But for me, it’s worth the wait. I have read that there is another substance that can be used that is cheaper. But this is readily available and it works.
