About this opportunity
The Department of Energy has published a Special Notice for a licensing opportunity related to a low-cost hot melt adhesive with improved adhesive strength. This technology offers a simplified processing method compared to traditional liquid-based adhesives, forming strong bonds quickly upon cooling and allowing for easy disassembly when necessary.
The purpose of this Special Notice is to seek potential partners interested in licensing this hot melt adhesive technology. The adhesive exhibits exceptional adhesion on various materials, including stainless steel, aluminum, and cast iron, while providing a facile disassembly capability. The technology leverages a polymer composite that melts at 100 degrees Celsius, creating chemical bonds that significantly improve adhesion between polymers and metal surfaces. Contractors have until September 29, 2024, to express their interest in this licensing opportunity. There are no set-aside requirements, and the Department of Energy is open to collaborating with a wide range of industries, such as packaging, manufacturing, hygiene, welding, woodworking, and electronics.
Notice text
Adhesives for metal parts typically are liquid-based which require complex processing. This technology is a hot melt adhesive that is mixed and applied in a solid form and after the heating and cooling cycle creates strong bonds with the substrates in a matter of seconds. These adhesives show excellent adhesion on the metal surface such as steel while they can be readily removed on demand. These adhesives can also adhere to aluminum, wood, paper.
Description
This technology is a high-performance hot melt adhesive (HMA), which is useful for a variety of applications where simplified processing, streamlined manufacturing, and end-product protection are paramount. One of the unique features of hot melt adhesives is their ability to form bonds quickly upon cooling, which is especially beneficial in situations where adjustments or repositioning of components are required. They create strong bonds in a matter of seconds. They also possess a reversible quality that enables them to be washed away or reactivated when necessary, allowing for easy disassembly without damaging the materials. This technology creates a hot melt adhesive using a polymer composite that uses temperature of 100 degree C to melt the material between the substrates where the strong bond to substrates will be created upon cooling. The adhesive resists corrosion and forms chemical bonds that significantly improve adhesion between the polymers and metal surfaces. HMA exhibits exceptional adhesion on stainless steel, aluminum, and cast iron, while providing a facile disassembly capability.
