- Typical Use
ACA 30-016 is designed, to bond and non-polar and polar surfaces such as polypropylene to aluminum and other metals. It will also bond metals to a variety of plastics and TPE/TPV, including Santoprene™. Since there are so many choices of metals and plastics in this class, testing is necessary to establish that a good bond is provided with a given application.
- Coating Method
The adhesive may be applied to metal foil by gravure printing, nip-fed reverse roll or wire wound bar coating methods. Brush, spray, or a paint roller may be used for unique shapes. The adhesive may be dried in a forced air oven at about 225°F. for a few seconds to yield an adhesive dry thickness between 0.3 and 0.75 mils. About 0.5 mils is a good place to start for adhesion evaluation. It may be necessary to run chill rolls on the oven output to avoid roll blocking and/or interleave a release liner.
Adhesive activation is accomplished at 400°F., 5 PSI, for 60 seconds. Conditions may differ depending upon the heat sealer and specific adherents.
ACA 30-016 is a dispersion and should be properly mixed prior to usage.
- Clean Up
Wash the equipment with water to remove the wet adhesive. The dry coating may require a toluene wash. Toluene is a flammable solvent and must be used according to OSHA safety standards.
