Pettit 97 Epoxy Thinner is a strong, fairly fast-evaporating thinner that allows two-part epoxies to flow out smoothly and yet flashes out fast enough to prevent sags.
Recommended use, add up to 10% Epoxy Thinner to epoxy primers and topcoats when necessary.
Among other uses, this product can be used to thin Pettit Protect and Tie-Coat Primer.
