What is UV Stable Resin?

Resin bound patios, driveways, paths and paths are long-lasting and easy to maintain.

There are two main types of driveway resin: non-UV stable and UV stable polyurethane. UV stable resin has a higher quality resin and is therefore more expensive.

What is the real difference between these two? The difference is quite obvious. UV stable polyurethanes or aliphatic (to the scientists out there), retain their clear colours and are not affected by UV radiation. Non UV polyurethanes which become darker brown under UV light (aromatic, to the scientists) turn a deeper brown. UV is required if you want the resin-bound surface to retain its original colour. UV is also important if you’re using a light-coloured aggregate mix. Without UV, your finished product won’t look like it.

Non-UV is acceptable when the aggregate blend is yellow/brown. But, unless the entire surface is exposed to UV, there will still likely be substantial colour variation from shading (which is highly probable; parked cars or gates, trees and plants pots, etc.). ).

According to some sources, Non-UV stable resins can be brittle due to UV exposure. However, the industry was originally completely Non-UV. It has been proven strong and durable. Non-UV resin often outperforms UV stable resin. Remember to only use proven materials.
