Unmatched UV Stability
Silicones are 100% UV stable, meaning they don’t degrade, chalk, or become brittle under prolonged exposure to sunlight.
Why it matters:
Metal roofs get intense UV exposure. Alternative coatings like acrylics or hybrids tend to chalk or lose elasticity over time—silicone doesn’t.
Waterproof & Impermeable
Silicone coatings are hydrophobic. They repel water and remain flexible even when submerged or exposed to ponding.
Why it matters:
Although ponding water isn’t typical on pitched metal roofs, wind-driven rain, laps, gutters, and fixings are all vulnerable points. Silicone’s waterproofing helps seal those areas without degrading.
Extreme Flexibility
Silicone coatings remain elastic in a wide temperature range (often -50°C to +150°C), accommodating metal roof movement (expansion/contraction) without cracking.
Why it matters:
Metal roofs expand and contract daily. Brittle or semi-rigid coatings will eventually fail at laps, joints, and fixings. Silicone handles dynamic movement exceptionally well.
Proven Reliability
Silicone coatings can last 25+ years without significant degradation, even in harsh industrial or coastal environments.
Why it matters:
Specifiers and industrial building owners want long-term protection and fewer lifecycle interventions—silicone is one of the few materials that can deliver on that promise.
| Advantage | Silicone Coatings | Hybrids / Others |
|---|---|---|
| UV Resistance | ✅ Excellent | ⚠️ Moderate |
| Water Resistance | ✅ Total barrier | ⚠️ Water-resistant only |
| Flexibility | ✅ Very high | ⚠️ Medium |
| Fire & BBA Certification | ✅ Often available | ❌ Rarely available |
| Long-Term Performance | ✅ 20+ years proven | ⚠️ 10–15 years typical |
| Movement Accommodation | ✅ Excellent | ⚠️ Variable |
Summary
Silicone coatings are chemically engineered for longevity, movement, and environmental resilience.
For metal roofs, where durability, movement, and weather resistance are mission-critical, silicone-based systems offer the most reliable, certifiable, and specification-friendly solution available.
Our Silicone Products
Did you know that Liquasil’s silicone roof coatings and liquid gutter liner are made to our own exacting recipes and are built from the ground-up at polymer level?
Some roof coating manufacturers simply dilute silicone sealant with huge amounts of solvent and then call them coatings.
The difference is remarkable, which is why most installers rave about the quality of Liquasil systems.
