TPO (Thermoplastic Olefin) roofing systems have become a top choice for commercial applications, known for their durability, energy efficiency, easy installation, and cost-effectiveness compared to other roofing materials. A crucial component of TPO roofing installation is the adhesive used to secure the membrane to the substrate. The advent of adhesive-coated TPO roofing discs has significantly enhanced the installation process, offering numerous advantages.
Understanding TPO Roofing Systems
TPO is a synthetic roofing membrane composed of rubber, ethylene-propylene, and polypropylene, which are chemically combined. Its popularity is attributed to its resilience against harsh weather, UV resistance, and excellent energy efficiency. Ensuring the proper installation of TPO roofing systems is vital for their longevity and performance.
TPO Roofing Disc Adhesive: Key Insights
Adhesive-coated TPO roofing discs offer a streamlined installation process. These discs can feature pressure-sensitive adhesives (PSA) or B-staged adhesives that are thermally bonded using induction welding techniques. While PSAs do not require special equipment, they lack the strength and durability provided by induction welding, which bonds the anchor to the membrane in seconds.
Simplifying Installation with TPO Roofing Discs
Using adhesive-coated TPO roofing discs offers several benefits for contractors and roofing professionals:
Enhanced Efficiency: Traditional adhesive application methods, such as using rollers or sprayers, can be time-consuming and messy. TPO roofing discs with B-staged adhesives can be applied in various temperature ranges and environments. The induction welding process allows for immediate heat activation, regardless of environmental conditions that might hinder the use of spray-on or pressure-sensitive adhesives. UNICHEM’s TPO adhesives require induction welding and specialized equipment, where electrical stimulation heats the metal disc, activating the adhesive and bonding it to the membrane.
Improved Accuracy: The adhesive discs are secured to the roof using manufacturer-recommended fasteners in a specific pattern. Pre-measured and pre-cut with pre-applied adhesive, these discs ensure consistent application thickness and eliminate the risk of over- or under-application. Once the induction welding process is completed, a permanent, highly durable bond is created between the disc, roofing anchors, and the TPO membrane, resulting in a uniform bond across the entire roof surface.
Environmental Benefits: Pre-applied adhesive on TPO roofing discs eliminates VOCs (volatile organic compounds) produced by spraying solvent-based adhesives. These discs are not susceptible to foaming in high humidity climates or premature drying in hot climates, making them an eco-friendly solution that aligns with the growing demand for sustainable roofing practices.
