What is UV Stable Resin?

Resin bound patios, pathways, and driveways will last many years. They are also hardwearing and require little maintenance.

Non-UV stable polyurethane and UV stable resin are the main types of resin that driveways can be made from. UV stable resin has a higher quality resin and is therefore more expensive.

What is the real difference between these two? It’s quite simple. UV stable polyurethanes, or aliphatic to scientists, retain their clear colour and are unaffected by UV radiation. Non-UV polyurethanes, on the other hand, turn a darker brown when exposed to UV light. UV is required if you want the resin-bound surface to retain its original colour. It is important to use UV when you are using light or coloured aggregates. Otherwise, the final product will not look the same.

Non-UV can be fine if the aggregate is yellow/brown. However there is a possibility of colour variations due to shading. ).

Sources claim that Non-UV-stable systems can become brittle from UV exposure over time. However, the industry began as 100% Non-UV and has proven to be durable and strong. Non-UV resins are often stronger than UV stabilised resins. Use materials with a proven track record.
