Ultrithane 31 is a high-build, one coat, anti-corrosive primer and topcoat, 2K high gloss metal polyurethane. This product has excellent resistance to weathering and will provide a long lasting finish.

This product can be applied direct to metal without the need of a primer. The anti-corrosive element within the paint ensures this product can be used as a 2k primer and topcoat in one.

2K High Gloss - Long Lasting Protection

Ultrithane 31 has a fine level of gloss which is long-lasting and protects surfaces when exposed to harsh chemicals. It is petrol and solvent resistant, and should any metal come into contact with a toxic substance, the coating effectively protects it against damage. It's also water-resistant, meaning the surfaces will not weather easily.

This product is highly durable and its acrylic polyurethane properties provide the right film thickness, making it the ideal choice for painting industrial tools, metal and agricultural machinery. With a smooth finish and lasting shine, this product makes any apparatus look brand new for longer. It promotes excellent adhesion on metal, stainless steel, aluminium and several other materials. When applied onto a surface free from dust, oil and other contaminates, the coating is more effective and visibly slick.

Ultrithane 31’s application is straightforward with the most satisfying results. With an airless spray, brush or roller, the coating covers all the desired areas. No special painting skills are required, which makes it all the more accessible and effortless to use. The paint provides an excellent state-of-the-art appearance as it has a high quality, glossy finish.

Colour Retention Is Key with 2K Paint

Colour retention is the key element of the formula, and only one coat is needed for rapid drying and desired results. Compatible with any RAL or BS colours, the paint is available in 5-litre or 20-litre tins. It can be used without a primer, or as a touch-up. Hiding blemishes and cracks, the coating settles firmly and conceals surfaces by adding a fresh and remodelled look.

High Build

High Solids; High Build; Glossy Finish; VOC Compliant; Direct To Metal; Anti-Corrosive Finish; Excellent Adhesion to most surfaces.

Hardener ** IMPORTANT NOTE

Requires 2K hardener. Mixing ratio advised is 4:1 - 4 parts Ultrithane 31 to 1 parts hardener. For the correct hardener see Ultrithane 31 Hardener.

When spraying 2K paints you must use a hardener with the paint to activate the first coat. Not using a hardener with this product may cause issues after use. Ultrimax takes no responsibility for issues arising with 2K paint used without the proper hardener.
