Stoppani Epoxy Thinner
Epoxy thinner for the spray and brush application of epoxy products.
2K epoxy primer. Used for hull protection in the paint processes on steel, wood, zinc-coated steel and gelcoat boats. It can be used on the ships bottom (under the waterline) as well as on topside ( above the waterline). On fibreglass boats it avoids osmosis formation and helps antifouling adhesion.
