HARDENER

    Hardener is an essential additive in the curing process of polyester and gelcoat resins. It initiates the chemical reaction that transforms the resin from a liquid into a solid, durable structure. The most commonly used hardener is MEKP (methyl ethyl ketone peroxide), typically added at 1–3% of the resin amount. Accurate dosing and thorough mixing ensure a successful result and safe handling.
