Transportation, industrial, and commercial customers use filters for thousands of separation and purification applications. Many of these require filters assembled with industrial adhesives and sealants.

Applications

Solvent and hydrocarbon
Oil and gasoline
Aviation fuel
Hydraulic fluid
Aviation hydraulic fluid
Coolant
High temperature
Water and brine

Reverse Osmosis Filter Adhesives

Reverse osmosis (RO) systems and the associated filter units have several demanding adhesive and sealing requirements. Component manufacturers vary widely in their production processes, and their adhesive systems must fit their assembly environment.

Reverse Osmosis Filter Applications

Reverse osmosis - sheet
Reverse osmosis - tubular
Permeators
FDA
