Filtration Adhesives

Reverse Osmosis/Ultra Filtration

RO-UltrafiltrationThe reverse osmosis/ultra filtration markets require adhesives that bond well to specialized membranes in separation process filters. In addition, filter manufacturers can widely vary in their production processes so the adhesive must also be formulated to fit different assembly scenarios. Polyset custom formulates polyurethane adhesives that adhere to both of these requirements. The chemical composition of these materials have a high degree of hydrolysis resistance and very little hardness loss in water at elevated temperatures (85˚C). These adhesives are also formulated with raw materials that will pass FDA and NSF requirements.
