PLH53-9 Epoxy Sealer Primer Descriotion

Overview
Two-component epoxy sealer primer formulated for penetration and sealing on cement concrete substrates and wood, with good adhesion and sealing performance.
It is specified as a dedicated compatible sealer primer for substrates such as cement mortar, concrete, and fiber cement boards.

Composition
Epoxy resin, solvent, additives, and imported curing agent; supplied as Part A and Part B.

Typical uses

  • For cement mortar, concrete, and fiber cement boards as a compatible sealer primer for subsequent coatings.

  • It is also stated to be suitable for porous substrates and for steel structure anti-corrosion/anti-rust as well as concrete corrosion protection.
