Jotun Hardtop One

Jotun Hardtop One is a premium one-component moisture-curing acrylic polysiloxane topcoat that delivers two-pack performance without isocyanates. This high-solids coating offers exceptional gloss and colour retention in atmospheric environments, with excellent UV and chemical resistance ideal for marine, offshore, and industrial applications. Formulated for brush and roller application with low dry spray, the product cures fully through moisture exposure and remains recoatable at any stage. It generates no di-isocyanates during hotwork or welding, making it safer for demanding operational environments. Superior adhesion and flexibility prevent cracking and peeling over extended service life. Recommended for topsides, decks, superstructures, offshore platforms, refineries, power plants, bridges, and building exteriors. Pre-qualified to NORSOK M-501 Edition 6 System 1 and contributes to Green Building Standards credits. Available in tintable colours (yellows in 20L packs only). Engineered to protect metal, composite, and industrial substrates where long-term performance and aesthetic finish are critical.
