Product Description

Ultrithane 21 - 2K High Gloss Paint

Ultrithane 21 is a high gloss, one coat polyurethane paint finish which can be applied directly to metal. It features acryl-polyurethane, high building enamel specially formulated for use with metals and alloys.

If you need a high performance paint with a high gloss finish which can withstand tough conditions, Ultrithane 21 is a great choice. This product is characterised by its high gloss retention, even when exposed to weathering.

Ultrithane 21 is recommended as an excellent top coat for metallic furniture finishing. It can also be used on chemical plants, window and door frames, agricultural equipment and many other articles.

This is a high solids compliant coating with excellent adhesion to all substrates including galvanised metal and aluminium.


Application and Preparation

Before applying on metal, surfaces should be clean, dry, degreased, without rust and/or calamine. When using on galvanised sheet, verify the perfect cleaning of the support and eliminate the white corrosion. If using on light alloys, ensure it is clean, dry and degreased.

As Ultrithane 21 is a finishing product, it doesn’t have anti-corrosive properties. However, apply Ultrithane 21 over Ultriprime 3 or Ultriprime 2 for a high build, anti-corrosive finish.

Ultrithane 21 is available in an unlimited colour range. We can colour match to an existing sample, to ensure you receive exactly the colour paint you require. Contact us to find out more about this service.



Requires 2K 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. You will receive an option to purchase hardener when you add this product to basket. You can choose to add the hardener or 'X' to add to basket without hardener. Ultrimax Coatings ltd takes no responsibility for issues arising with 2K paint used without the proper hardener.
