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.
