-
How does Cilbond® perform in extreme conditions?
Cilbond® adhesives are designed and formulated using in-house made unique polymers and are made under stringent process conditions. Hence, Cilbond® adhesives perform well under stress, vibration strain, and temperature fluctuations compared to the traditional Rubber to Substrate bonding systems.
-
What are the benefits of using Cilbond® over traditional adhesives?
Cilbond® offers several key advantages:
- Rubber bonding to metals without the need for primers
- High durability in dynamic and static loads
- Resistance to oil, chemicals, and high temperatures
- Simplified application and processing
-
Can Cilbond® be used as a structural rubber metal bond solution?
Yes, Cilbond® is trusted worldwide for structural rubber metal bond applications, including bushings, mounts, and dampers. It ensures long-lasting bonds that withstand mechanical and environmental stress.
-
What types of industries use Cilbond®?
Industries that benefit from Cilbond® include:
- Automotive (engine mounts, suspension bushings)
- Aerospace (vibration dampening components)
- Industrial (rollers, isolators)
- Construction (sealing and vibration control)
- Oil & Gas (Stators)
- Power Grid (Connectors)
-
How does Cilbond® compare to general-purpose metal and rubber adhesives?
Unlike general-purpose metal and rubber glue, Cilbond® is purpose-formulated for bonding rubber to metals and offers enhanced chemical resistance, longer service life, and better adhesion under dynamic stress.
-
Does Cilbond® support bonding without primers?
Yes. Many Cilbond® products enable direct bonding to metals including steel, aluminum, and other alloys — simplifying the manufacturing process while ensuring strong rubber metal adhesive performance.
Cilbond® one-coat systems eliminate the need for a primer, offering the same environmental resistance and rubber tear strength as conventional two-coat systems. H.B. Fuller's innovations reduce material usage, application, and drying times without sacrificing quality.
-
What support is available?
H.B. Fuller offers extensive technical support by providing product recommendations, conduct application specific technical service projects, process reviews and root cause analysis. Our Technical Service and Analytical labs can provide a variety of technical support based on customer needs.
-
Can Cilbond® handle dynamic loads and stress?
Yes. Cilbond® adhesives are tested for high dynamic stress and fatigue resistance. Whether you're bonding rubber to metal in moving parts or static mounts, Cilbond® maintains bond integrity even in extreme environments.
-
Do you have water-based and solvent-based options available?
Yes, we have a variety of water-based and solvent-based options depending on our customers’ unique needs. Our water-based portfolio supports is ideal for customers, manage their EH&S requirements – including increasing safety, reducing VOCs, and managing overall costs.
-
What extreme conditions must brake pads endure, and why are strong adhesives critical in these applications?
Brake pads must withstand rapid temperature fluctuations ranging from sub-zero to 750°C within seconds. Additionally, they are exposed to harsh contaminants such as oils, fuels, and salt spray, making it essential for bonded pads to maintain integrity under extreme heat, chemical exposure, and corrosive environments. High-performance adhesives are crucial to ensure durability and safety.
-
What type of products does Cilbond® offer for bonding brake pads?
Cilbond® offers a range of water-based bonding products specifically formulated for use in both Original Equipment Manufacturer (OEM) and Aftermarket brake pads. These products are designed to surpass automotive industry standards and outperform traditional solvent-based adhesives.
-
What are the key features of Cilbond®'s brake pad adhesives?
