New adhesives to optimize filter manufacturing

Filters are used in many different areas and applications to clean air and liquids. When producing consumer and industrial goods, adhesives play a decisive role. To meet the high expectations of industry, Henkel invests in research and develops new technologies. At the FILTECH 2011 trade fair, Henkel will be presenting an up-to-date product portfolio for construction of modern filter systems.

Henkel will be presenting a cold-cure rigid polyurethane foam adhesive for effective end-cap bonding of liquid and air filters namely Macroplast UK 8524. When compared to conventional products, this adhesive offers numerous benefits: Unlike PVC plastisols, Macroplast UK 8524 can be used and cured at room temperature. This reduces both the cure time and high temperature required which results in significant energy cost savings during the manufacturing process. It also lowers production costs and has a positive impact on environmental performance. Further cost savings are achieved thanks to the rigid foam adhesive’s processing properties: Macroplast UK 8524 foams without needing any further additives, achieving a volume increase of up to 270 percent and forms a closed-cell glue foam with a density of 0.4 g/cm³. As a result, less adhesive has to be used than before, reducing product costs by up to about 30 percent. Another feature worth mentioning is the adhesive’s excellent resistance to engine oil, which makes it suitable for use in automotive industry applications as well.

In addition Henkel has also developed two other adhesives, Macroplast UK 8630 and 8640 which were specifically engineered for use in transport and other applications. These polyurethane-based products are permanently resistant to bio-diesel and other bio-fuels, thus ensuring the durability of fuel filters in retrofitted vehicles. Another plus is their high temperature stability: With a glass transition temperature (TG) of over 100°C, the adhesives can be used in many different applications. 

Another product from the Macroplast range that will be showcased at FILTECH 2011 is primarily intended for stabilizing water filters. The larger the diameter of the filter, the more unstable it becomes in use. Filters for water and beverage production are frequently very large, and have to withstand high pressures. Henkel has responded to the special needs of the industry by adding a new product to its standard range – Macroplast CR 3526/4200. This is a rigid filter adhesive for stabilizing large-diameter filters. Manufacturers benefit from this new technology by achieving better quality and hence greater durability of the filters.

Different applications need different adhesives, and Macroplast UK 178 is the preferred choice for spiral wound reverse osmosis filters. This adhesive has already established itself in the USA and Asia in water purification and gas cleaning filters. Macroplast UK 178 meets the highest standards and has been certified in accordance with the U.S. drinking water standard NSF 61. As this product has been very successful overseas, Henkel is now introducing this adhesive in Germany as well.

Visitors can learn all about the latest product innovations and how Henkel adhesives have made a positive contribution to the filter industry at stand B5 in Hall 1 at FILTECH 2011.
