UV Resin vs Non UV resin

The difference between UV stable and non-UV stable resin-bound gravel lies in how the resin reacts to sunlight (UV rays) over time. Here's a breakdown of both options:

UV Stable Resin Bound Gravel

• Definition: UV stable resins are designed to be resistant to the harmful effects of UV rays from the sun. This means they maintain their color, clarity, and integrity when exposed to sunlight.

• Benefits:

  1. Color Retention: UV stable resins prevent yellowing or discoloration caused by UV exposure, which helps maintain the aesthetic appeal of the surface for many years.

  2. Durability: The resin is less likely to degrade or become brittle when exposed to UV rays, offering a longer lifespan for the resin-bound gravel surface.

  3. Low Maintenance: Since UV stable resins are resistant to environmental factors like sun exposure, they require less maintenance over time to preserve their appearance.

• Drawbacks:

  1. Higher Cost: UV stable resins tend to be more expensive than non-UV stable options, as they are made with advanced formulations that offer better resistance to UV degradation.

  2. Application Sensitivity: Proper installation and curing are still important to ensure optimal performance of the UV stable resin.

Non-UV Stable Resin Bound Gravel

• Definition: Non-UV stable resins do not have the same protection against UV rays, which can lead to color fading and degradation over time.

• Benefits:

  1. Lower Cost: Non-UV stable resins are generally cheaper than their UV stable counterparts, making them a more budget-friendly option.

  2. Suitable for Shaded Areas: If the resin-bound gravel will be installed in areas that are shaded most of the time (e.g., under trees, covered areas), UV degradation is less of a concern, and non-UV stable resin may work well.

• Drawbacks:

  1. Discoloration: Over time, the resin will likely begin to yellow or fade due to UV exposure, especially in areas that get direct sunlight. This can lead to a less attractive surface.

  2. Degradation: Non-UV stable resins are more susceptible to becoming brittle and breaking down when exposed to sunlight, which can reduce the overall lifespan of the surface.

  3. Higher Maintenance: Since non-UV stable resins degrade faster, the surface may require more maintenance or re-coating sooner than UV stable resin.

Which Should You Choose?

• UV Stable Resin Bound Gravel is generally the better option for outdoor installations that will be exposed to the sun. It's particularly important if you want to maintain the color and appearance of the surface for a longer time with minimal maintenance.

• Non-UV Stable Resin Bound Gravel may be acceptable for shaded areas or in applications where budget is a major concern and long-term aesthetics are not a priority.

In summary, UV stable resin offers better durability, aesthetic retention, and overall performance, especially in areas exposed to sunlight. Non-UV stable resins, while more affordable, can suffer from discoloration and reduced lifespan when subjected to UV exposure.
