Rampf Polymer Solutions, a developer and manufacturer of reactive plastic systems based on polyurethane, epoxy, and silicone, has broadened its portfolio by adding high-performance assembly adhesives to its customized casting resin systems for sealing, casting, and coating.
“Our aim was to develop superior adhesive solutions for the widest possible range of assembly applica- tions,” explains Dr. Klaus Schamel, Managing Director of Rampf Polymer Solutions. “And we have suc- ceeded in developing a very broad spectrum of properties that enable us to offer our customers tailor- made, high-quality polyurethane, epoxy, hybrid, silicone, and hot-melt systems.”

Customized solutions
Dr. Wolfgang Hodek, Senior Key Technology Manager Adhesives, is confident that “our products will succeed on the market thanks to their high quality and customer-specific design. By heavily prioritizing RD and utilizing our highly effective production processes, we are able to rapidly translate the needs of our customers into high-performance products.”
The focus of further developments now lies in optimizing the mechanical properties of tough-elastic reac- tion adhesives, particularly for fiber-reinforced composite materials, “which includes using the latest raw materials in hybrid (silane-functionalized) prepolymer technology,” says Hodek.
Besides these basic products, the company is also able to provide precise solutions to meet very specific industrial requirements. “As a strong development partner with a large laboratory and comprehensive applications technology, our clearly defined aim is to lead the market in individual seg- ments,” Dr. Schamel points out.
Material and machine from a single source
The synergies utilized with Rampf Production Systems, one of the world’s leading manufacturers of low-pressure mixing and dispensing systems and renowned automation specialist, also help optimize the development, testing, and applications of adhesives. “The increasing requirements being made on bonded systems – for instance in terms of environmental influences, required strength, and curing times – call for sustained efforts to keep on optimizing adhesives. These factors can influence the processing properties, which means the mixing and dispensing systems then also need adapting accordingly,” ex- plains Bernd Faller, Managing Director of Rampf Production Systems. “A very close collaboration is essential between the adhesive manufacturers and plant manufacturers in order to develop the best so- lutions. This high degree of collaboration occurs on a daily basis between both companies.”
