Air and Gas Filter Adhesives

Air and gas filters are used in virtually every industry and in many consumer and residential applications.  They include air/solid, air/liquid, air/air separation for industrial, medical, transportation, commercial and consumer markets.

Applications

• Air/liquid and air/solid
• Gas purification/permeator
• Compressor/separator
• Transportation
• Vacuum
• High or low temperature

HEPA Filter Adhesives

High Efficiency Particulate Arrestors (HEPA) filters encompass a broad spectrum of industries and applications.  They range from the strict requirements of the Class 1 cleanroom for semiconductor fabrication to the filters in consumer vacuum cleaners.  Our family of products offers a selection of key benefits such as flame retardancy, low out gassing, FDA compliance, adhesion and penetration, sealant strength, and temperature and chemical tolerance.

Applications

• HEPA – Industrial and consumer
• HEPA – Critical cleanroom

Chemical and Fluid Filter Adhesives

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
