What is the minimum flash point required for liquid adhesive coatings used on filters?

The minimum flash point required for liquid adhesive coatings used on filters is crucial because it indicates the temperature at which the adhesive can form flammable vapors. A flash point of 325 degrees is typically considered safe for many industrial applications, including the production of filters where a balance between effective adhesion and safety is necessary.

Selecting a flash point above this level, such as 350 or 400 degrees, may not only be unnecessarily stringent but could also lead to issues with the adhesive's performance or application processes at lower temperatures. Furthermore, a lower flash point, such as 250 degrees, poses a significant fire hazard during usage, making it unacceptable for high-performance applications that adhere to safety standards. Thus, a minimum flash point of 325 degrees ensures that the adhesive remains effective while minimizing risks associated with flammability.
