Elastomeric Bitumen-Polymer Hybrid Coating
(UV-Stable Color-Integrated & Metal-Restoration Specification)
Product Overview
The definitive high-performance restoration solution for aging structural roofscapes. This single-component, water-based system utilizes an advanced Hybrid Matrix, encapsulating high-grade emulsified bitumen within a UV-stable, weather-resistant polymer lattice. Specifically engineered for the seamless revitalization of concrete and metal roof assemblies, it creates a high-build, “rubberized” shield that integrates architectural aesthetics with professional-grade waterproofing.
Core Advantages
▪ UV-Stable Color Integration: Unlike traditional black bitumen coatings, this hybrid technology
allows for a range of architectural colors without compromising the membrane’s integrity. The integrated pigments are shielded within the polymer matrix, ensuring long-term color retention
and superior resistance to solar degradation in exposed environments.
▪ Aggressive Cross-Material Adhesion: Engineered with a high affinity for diverse substrates, particularly aging metal and concrete. The modified bitumen core ensures a permanent, molecular-level bond, preventing delamination and inhibiting rust propagation on metal decks.
▪ Extreme Thermal Resistance Spectrum: With a performance range from -15°C to 110°C (5°F to 230°F), the membrane maintains its elastomeric memory without becoming brittle in winter or flowing in intense summer heat. It effortlessly accommodates the extreme thermal cycling
common in metallic structures.
▪ Reinforced System Longevity: Optimized for use with non-woven reinforcement fabrics to
create a high-strength, fully-adhered Liquid Applied Membrane (LAM). This system-based approach provides massive tear resistance and long-term durability for high-exposure renovation projects.
Engineered Applications
▪ Seamless restoration and waterproofing of aging corrugated metal and standing-seam roofs.
▪ High-productivity refurbishment of commercial concrete roof decks and fiber-cement panels.
▪ Architectural waterproofing for exposed structures requiring specific color aesthetics.
▪ Energy-efficient “Cool Roof” upgrades (when utilizing high-reflectance light color specifications).
System Integration: The Architectural Metal-Restoration Matrix
To fully capitalize on the aesthetic and waterproofing capabilities of a colored Bitumen-Polymer hybrid, you must confront the brutal physical realities of aging metal roofs. Corrugated metal is plagued by multidirectional thermal expansion, active oxidation (rust), and thousands of vibrating mechanical fasteners. Applying a water-based liquid coating directly over expanding seams or active rust is a fatal engineering contradiction. Eliminate flash-rusting, reinforce structural joints, and secure your architectural finish by integrating these mandatory components:
Active Rust Encapsulation & Fastener Detailing:
Must pair with: Ultra-Performance MS Hybrid Liquid Membrane
Why it’s critical: This hybrid coating is water-based. Applying any water-borne system directly to oxidizing metal or exposed fasteners invites immediate “flash-rusting” and coating delamination. This primer-less, UV-stable MS Hybrid liquid must be deployed first as a detailing weapon to chemically encapsulate surface rust and perfectly seal all exposed screw heads. It provides an impenetrable, rust-arresting foundation before the water-based bitumen is applied.
Thermal Expansion & Metal Seam Reinforcement (The Skeletal Matrix):
Must pair with: High-Tenacity Elastomeric Flash-Bond Matrix
Why it’s critical: A metal roof acts like a massive thermal engine, expanding and contracting violently between -15°C and 110°C. While the hybrid coating possesses extreme elastomeric memory, a thin liquid film cannot bridge a moving 5mm metal lap seam in isolation. This cold-applied, non-woven butyl tape must be centered over all horizontal and vertical metal overlaps. It creates a high-tensile structural “skeleton” that absorbs severe thermal shear, while its fleece surface completely fuses with the liquid coating.
Vibrational Penetration & HVAC Gas-Lock:
Must pair with: Architectural High-Performance PU Sealant
Why it’s critical: Metal roofs magnify the mechanical vibration of heavy HVAC units, exhaust vents, and skylights. Brushing a liquid membrane against a vibrating metal curb guarantees fatigue cracking. This Class 25 F dynamic polyurethane sealant must be heavily extruded around all roof penetrations and flashings prior to coating. It acts as an independent, high-mass elastomeric shock-absorber that isolates kinetic energy from the continuous waterproof skin.
