Product Description
Epifanes Epoxy Primer, White, 750ml (EXPW.750) is a tough, modern two‑component zinc‑phosphate epoxy primer formulated for use above and below the waterline. It provides excellent filling properties, strong adhesion, fast drying, and easy sanding.
This primer offers outstanding rust protection on steel, deep penetration and sealing on wood, and superior adhesion and osmotic protection on fiberglass (FRP). With sufficient film build, Epifanes Epoxy Primer can fully seal a surface against water intrusion and provides excellent scratch resistance above the waterline.
Epifanes Epoxy Primer is unique in that it is recoatable with both one‑component and two‑component Epifanes paints, making it highly versatile for new construction, repair, and maintenance of existing epoxy systems.
Package includes 600ml Component A and 150ml Component B (4:1) for a total mixed volume of 750ml. Download the technical data sheet here.
