Jotun Hardtop AX Polyurethane Topcoat 20L

High Performance Acrylic Polyurethane Topcoat for Marine and Protective Coatings

Jotun Hardtop AX is a two-component acrylic polyurethane topcoat designed to deliver a durable, high quality finish in marine and protective coating systems. Supplied in a 20L kit, it is engineered for professional use where long lasting colour and gloss retention are required.

This topcoat provides a smooth, aesthetic finish while offering resistance to weathering and environmental exposure. It is commonly used as the final coat in coating systems applied to steel and other substrates in marine and industrial environments.

Hardtop AX is suitable for use over compatible primers and intermediate coats, forming part of a complete coating system designed for long term protection and visual performance.

Designed for spray, brush or roller application, it delivers consistent results when applied in accordance with Jotun specifications.

Recommended Thinner

Jotun Hardtop AX requires Jotun Thinner No.10 when thinning is necessary for application.

• Formulated for polyurethane coating systems
• Ensures correct viscosity for spray, brush and roller application
• Maintains finish quality and coating performance
• Suitable for cleaning application equipment

Important: Always follow the Jotun technical data sheet for thinning ratios. Do not substitute with No.7 or No.17 thinners, as this may affect curing, gloss and long term durability.
