How to Improve the Weathering Durability of Exterior Coatings?

UV Stabilizer Solutions by SONGWON Trusted by Global Coating Leaders

🌞 UV Radiation – The Invisible Enemy of Exterior Coatings

In outdoor environments, coating systems must endure harsh conditions such as:

• UV radiation (UV-A & UV-B) – degrades the polymer matrix, causing loss of gloss, embrittlement, and cracking
• Oxygen, heat, and light – trigger photo-oxidation reactions
• Moisture, acid rain, salt, and pollutants – reduce adhesion and protective function

Consequences of UV degradation:

• Fading and discoloration
• Surface chalking, microcracks
• Decreased gloss and aesthetic value
• Loss of barrier function → substrate corrosion or degradation

🔬 The Role of UV Stabilizers in Coating Protection

To extend the service life of exterior coatings, modern formulations rely on UV stabilizers – functional additives that interrupt the photo-degradation process.

There are two primary classes:

1. UV Absorbers (UVA)

• Absorb harmful UV radiation (typically 280–400 nm)
• Convert UV energy into harmless heat
• Protect resin and pigment from direct exposure

🔍 Common chemistries: Benzotriazoles, Benzophenones, Triazines

2. HALS (Hindered Amine Light Stabilizers)

• Do not absorb UV directly
• Scavenge free radicals formed during photo-oxidation
• Interrupt chain degradation reactions
• Regenerative: HALS can repeatedly neutralize degradation intermediates

➡️ Combining UVA and HALS offers synergistic protection, ensuring long-term color retention, gloss, and film integrity in demanding outdoor applications.
