H.B. Fuller EV Seal 500

H.B. Fuller EV Seal 500 is a thermal plastic hot melt PSA designed for use in gasketing and sealing applications. It is especially suitable for sealing battery pack modules where accessibility and serviceability are a high priority. With the resealable nature of this material, repeated opening and closing of a battery enclosure is simple, easy, and reliable. The EV Seal 500 offers a robust solution for preventing dust and moisture intrusion into any enclosure. This material is recommended for use with steel, aluminum, and cast iron.

Application Method
  1. Coating surface area should be clean and free of any oils, residues, dust, or any other contaminants
  2. Apply to primary substrate. Primary substrate is the preferred substrate in which the material will remain permanently adhered. Secondary substrate will be married to the primary and material will release from during servicing.
  3. Apply using appropriate Hot Melt dispensing equipment. Adjust heating and pressure parameters to achieve appropriate flow rate.
  4. Allow 5 minutes for material to cool to room temperature prior to assembly of enclosure.
