When selecting a coating for outdoor surfaces like patios, driveways, pool decks, and commercial spaces, it’s critical to choose a material that can withstand prolonged exposure to sunlight. Many traditional coatings experience fading, yellowing, and structural breakdown due to ultraviolet (UV) radiation, causing premature wear and costly repairs.
At Tru Grit Coatings, we take UV resistance seriously by incorporating advanced UV stabilizing agents into our Tru NanoX Polyaspartic 85 resins. These high-performance coatings provide long-lasting durability, color retention, and superior adhesion, even in the harshest outdoor conditions.
The Impact of UV Exposure on Coatings
Why UV Rays Cause Damage
Sunlight emits ultraviolet (UV) radiation, which interacts with materials at a molecular level. In standard coatings, UV exposure can break chemical bonds, leading to:
Color Fading – The breakdown of pigments and binders results in loss of vibrancy.
Yellowing – UV light causes oxidation in certain polymers, creating unwanted discoloration.
Brittleness & Cracking – Over time, UV exposure depletes plasticizers, leading to loss of flexibility and eventual cracking.
Delamination – A compromised surface can lose adhesion, leading to peeling and flaking!
Many traditional coatings—including epoxies and urethanes—suffer from these UV-related issues, making them less ideal for outdoor use.
How Tru NanoX Polyaspartic 85 Resins Achieve UV Stability
Unlike traditional coatings, Tru NanoX Polyaspartic 85 is engineered with a multi-layered UV protection system to block, absorb, and neutralize UV radiation before it can cause damage.
Advanced UV Stabilizers for Maximum Protection
Our polyaspartic resins are fortified with organic UV stabilizers, specifically hindered amine light stabilizers (HALS) and UV absorbers (UVA). These compounds actively intercept UV rays before they can degrade the coating.
Hindered Amine Light Stabilizers (HALS) – HALS work by neutralizing free radicals, the unstable molecules formed when UV rays break apart polymer bonds. This process prevents oxidation and extends the lifespan of the coating.
UV Absorbers (UVA) – UV absorbers, such as benzotriazole derivatives, absorb harmful UV rays and dissipate the energy as harmless heat. This prevents UV light from reaching the coating’s chemical structure.
By combining HALS and UVA technology, Tru NanoX Polyaspartic 85 resins achieve superior protection against fading, yellowing, and cracking, ensuring long-term performance.
High-Solid Polyaspartic Chemistry
Traditional epoxy coatings have a tendency to chalk and yellow when exposed to UV rays. Polyaspartic resins, on the other hand, are formulated with high-solid aliphatic compounds, meaning they offer:
Stronger molecular bonds that resist UV degradation.
Improved flexibility to withstand temperature fluctuations and outdoor stress.
Superior adhesion to concrete, preventing peeling or delamination.
Reinforced Crosslinking for Long-Term Durability
The chemical structure of our Tru NanoX Polyaspartic 85 resins allows for enhanced crosslinking, forming a dense, high-performance film over the concrete surface. This strengthens adhesion, repels moisture, and provides superior weather resistance.
The Benefits of Tru NanoX Polyaspartic 85 for Outdoor Applications
By using scientifically advanced UV protection methods, Tru Grit ensures that outdoor spaces maintain their aesthetic appeal and structural integrity for years to come.
Key Benefits:
