Water filter enhanced by H.B. Fuller adhesives.

Liquid Separation and
Water Filter Adhesives

According to a 2014 World Health Organization and UNICEF Report, 748 million people lack access to an improved drinking water source. UN-Water statistics state that “water scarcity already affects more than 40 percent of the people on the planet.”

Our membrane separation adhesives for RO membranes and hollow fiber filters are designed to help remove contamination and provide clean drinking water. These liquid filter adhesives are accompanied by a field proven longevity and safety performance record, and they are part of our global supply network.

We utilize our global manufacturing expertise to provide local service and filter know-how.
