Pressure Sensitive Adhesives (PSA’s) are commonly used in conjunction with adhesive backed gaskets and seals. Whether the purpose is to form a structural bond, act as a manufacturing aid, or improve the sealing performance of an irregular surface, choosing the best adhesive system for an application is important. PSA’s are the most common adhesive types for gaskets. Typically supplied on the gasket, the assembler then removes a release liner to press-fit the gasket in place.

Key considerations when selecting a Pressure Sensitive Adhesive:

• Adhesion Properties – What is the gasket adhering to? Metal? Plastic?
• Temperature Capabilities – What temperature range is required?
• Chemical Compatibility – Will the adhesive be exposed to any chemicals?
• Dimensional Stability – Do you need to eliminate stretching for assembly?
• Weather Resistance – Will the adhesive be exposed to outdoor elements?
• Special Properties – Does the adhesive need to be electrically/thermally conductive, flame retardant?

PSA’s typically come in the following formulations:

• Acrylic Based – Adheres well to most gasketing materials and surfaces while offering a good operating temperature range (-50°F/-46ºC to +350°F/+177ºC intermittent)
• Silicone Based – Adheres well to silicone elastomers and fair to other surfaces. Silicone adhesives offer the widest operating temperature range, (-80°F/-62ºC to +450°F/+232ºC) but are also the highest cost.
• Rubber Based – For general use applications, typically lower performance and lower cost. Typical intermittent operating temperature range of (+50°F/10ºC to +150°F/10ºC).
