Established in 1876, Henkel can look back on a 140-year history of successful business performance. The group employs more than 53,000 people worldwide, forming a diverse team bound together by a strong corporate culture, a shared corporate objective, and common values. Henkel preferred shares are listed in the German stock index DAX. Henkel has a balanced and diversified global portfolio across three business units – Adhesive Technologies, Beauty Care, and Laundry & Home Care. Henkel Adhesive Technologies is the global market leader in the adhesives sector and offers the world’s widest range of adhesives and sealants, as well as products for surface treatment.
The Sonderhoff Group, which has been part of Henkel AG & Co KGaA since the beginning of July 2017, is a system provider for materials, machines and contract manufacturing. It specializes in customized sealing, gluing and potting solutions using FIP(F)G technology. Manufacturer of foam sealing, adhesive and potting systems based on polyurethane, silicone or PVC, as well as mixing and dosing systems for the automated application of material to industrial components – Sonderhoff supplies everything for its customers from a single source. It also offers customers contract manufacturing for foam sealing, gluing and potting of components. This ranges from sampling prototypes to small batches right up to mass production. The customer has the choice of more than 1,000 formulae, alongside multi-patented knowledge and many years of experience.
Manufacturers of liquid filtration systems in the water, food and beverage industries face the challenge of having to continually raise the reliability and efficiency of their products. But they also need to cut the maintenance costs when cleaning filtration systems. Henkel has developed a two-component epoxy adhesive, Loctite EA 9452, to meet these high requirements. This adhesive is characterized by very good acid and alkali resistance when filtering liquid substrates at pH2 to pH12. Above all, the product has a high temperature stability up to 85 C. “This allows the intervals between the cleaning cycles to be extended, reducing costs and raising production output,” says Frank Lenz, business development manager of Filtration for Europe at Henkel.
Henkel also offers Technomelt AS 5115, which is a solvent-/BHT-free hot melt adhesive based on ethyl vinyl acetate. The product is approved to VDI 6022 for use in ventilation and air conditioning systems and is also used for the bonding of clean room filters. Technomelt AS 5115 can be used up to 100 C, impressing with its excellent fungal and bacterial resistance that meets ISO 846. This reduces the effort required for cleaning and disinfecting the filter elements and apparatus.
Sealing specialist Sonderhoff is a manufacturer of two-component foam gaskets, adhesives and potting compounds as well as mixing and dosing systems. Sonderhoff’s Fermadur adhesive range bonds the folded filter pack to the interior of the filter frame and is applied using a SMART-M dosing cell. Thanks to the foamed cell structure and the resulting lower density, this product achieves high efficiencies in filter production. The amount of adhesive per filter can be reduced by up to 50 percent thanks to the foamed cell structure. This saves both money and weight, while continuing to meet the requirements for high-quality filter bonding, says the company.
