LJF Custom Coatings offer high-quality, reliable Solid Polyurethane coating applications across the same broad range of OD’s and coating thicknesses as GsPU.  Predominantly used as a field joint coating for spool work undertaken, Solid PU can still be utilised as a standalone insulation coating and can be applied over corrosion-resistant primers such as FBE or other barrier layers as required.

What is Solid PU?

Solid PU is a high-performance elastomeric material known for its excellent abrasion resistance, toughness, impact strength and flexibility, Solid PU is ideally suited for components such as bend restrictors, bend stiffeners, field joints, and riser protection. Its non-foamed, dense structure ensures long-term durability under high mechanical loads and hydrostatic pressures, making it a reliable choice for both shallow and deepwater applications.

Key Properties

• High abrasion resistance – resists wear from mechanical contact
• Excellent impact strength - absorbs and dissipates energy under impact
• Superior tear & cut resistance – maintains integrity under mechanical stress and sharp edge contact
• Hydrolysis resistance – maintains mechanical properties in submerged environments
• Good flexibility and elasticity – withstanding bending and movement without cracking
• High load-bearing capacity – suitable for applications subjected to heavy loads or hydrostatic pressure
• Strong adhesion to primed steel or anti-corrosion coatings
• Thermal stability – can perform up to 125°C (dry)

Typical Applications

• Pipes
• Bends, Elbows & Fittings
• Pre-Fabricated Spools
• Risers
• Manifold Spools
• Field Joint Coating
• Half Shells

Why choose Solid PU?

Solid PU is a versatile coating solution that performs exceptionally both as a standalone insulation and protection system, and as a compatible field joint material for insulation systems using Glass Syntactic Polyurethane (GsPU) or Polypropylene. Its excellent adhesion to various substrates and seamless integration with adjacent insulation materials make it ideal for maintaining thermal and mechanical continuity across spools and pipeline joints. Whether used independently for abrasion and impact resistance, or as part of a multilayer system, Solid PU provides robust, long-term protection in demanding subsea environments.
