Adhesive and coating systems
In metal air filters, a specific adhesive is required to bond the frame (galvanized sheet) to the metal mesh. This adhesive must withstand the harsh environmental conditions resulting from heat, pressure, or chemicals. Various filter adhesives are available, and choosing the right one requires consideration of the production process and desired characteristics of the final product (application conditions). The two-component, solvent-free polyurethane adhesives designed for metal filter assembly (air and oil) by Imen Polymer Chemie Company come in various colors, curing rates, viscosities, and hardness levels. Additionally, this product cures at room temperature, but curing is accelerated with heat. This adhesive is used in heavy-duty vehicle air filters and light vehicle oil filters.
