Engineering Casting Resins (C.A.S.E.)

Combining durability with versatility

Numerous applications. Customized solutions.

At RAMPF, C.A.S.E stands for highly resilient elastomers, customized casting and construction materials, and an all-encompassing portfolio of innovative reaction resins.

Our RAKU® PUR (polyurethane), RAKU® POX (epoxy), RAKU® SIL (silicone), and RAKU® Melt (hotmelt) systems are used in:

  • Filters (casting, sealing air, oil, and hydraulic filters)
  • Insulating panels (gelcoat layer and foam) for refrigerated vehicles
  • Window frame bonding
  • Edge casting for laboratory equipment, hospitals, and schools
  • Elastomer molds for the cement industry
  • Abrasives

Our diversity in this field means we are much in demand as a solution partner. We tailor our product development to your specific requirements regarding both the product and the processing procedure.

Together with application expert RAMPF Production Systems, we develop products that are used on the simplest manual mixing and dispensing systems to highly automated dispensing technology.

Material, machine, process – benefit from RAMPF’s highly competent complete service.

Our solutions for your applications

Customized solutions result in high-performance products. The encompassing product range C.A.S.E. (Coatings, Adhesives, Sealants, and Elastomers) can withstand highest stresses as well as mechanical and chemical impacts. That is why our RAKU® PUR (polyurethane), RAKU® POX (epoxy), RAKU® SIL (silicone), and RAKU® Melt (hot melt adhesives) systems are used worldwide in a variety of applications.


Reactive two-component systems developed and produced by RAMPF Polymer Solutions are used, amongst others, for bonding filter end plates to the filter medium and in the manufacture of filter end plates. This is where casting systems with good flow and adhesion properties as well as high chemical resistance are required. Due to their wide range of properties and comprehensive performance spectrum, RAMPF’s engineering casting resins are used in a wide variety of industries and applications, including air filters, HEPA air filters, dust filters, oil and hydraulic filters, and filters for ventilation systems. We will find the best solution for your industry and design concept.

Edge casting

Due to their high mechanical and UV resistance, construction casting resins developed and produced by RAMPF Polymer Solutions are used to protect the edges of doors, furniture, and training equipment in hospitals, schools, and kindergartens. Thanks to their high chemical resistance, the edge casting systems can also be used for laboratory furniture. The door and furniture edges are permanently protected against mechanical damage, thus increasing their service life. Protect your door and furniture edges with construction casting resins from RAMPF Polymer Solutions.


Better than the real thing: Thanks to their excellent mechanical properties and durability, construction casting resins developed and produced by RAMPF Polymer Solutions facilitate the manufacture of bricks and concrete slabs in a wide range of geometries and structures. Wetcast molds not only have a brilliant, lifelike appearance, but also exhibit very low water absorption, very low shrinkage, and outstanding stability. The two-component polyurethane construction casting resins cover the hardness range of Shore A25 - 110 and are used for the manufacture of molds and structures for surface replication, model (clone) production, and wet mound production.

Corner angle bonding

A high-performance adhesive is required for the constructional bonding of corner angles in aluminum windows and doors. The polyurethane-based, two-component adhesive developed and produced by RAMPF Polymer Solutions meets all the requirements:  It has very good adhesion to aluminum, very good strength, is solvent-free, does not drip off, and is also moisture-resistant. The two-component RAKU® PUR adhesive from RAMPF Polymer Solutions stands for outstanding results in corner angle bonding.
