- Recommended Uses
GLASSTACK 25 is a slower tacking water base insulation adhesive specially formulated for extrusion coil lines, rotobonders and spray applications where a fast dry time is not necessary when adhering fiberglass insulation to sheet metal ductwork.
- Application Instructions
Prior to application clean the surface of all oils, dirt, and foreign matter for best results.
Brush/Roller: Brush or roll adhesive to a desired thickness of 5 mils wet film thickness at a coverage rate of 90% minimum to achieve maximum performance.
Spray Gun: Binks 2001 stainless steel gun, or equivalent, with a .066SS fluid nozzle and a .066SD air cap. Operate the above spray setup at approximately 15 psi fluid pressure and 40 psi atomizing pressure. Ideal coverage is 90% of the surface for maximum bond strength.
Spray Coil Line: Use approximately 20 psi fluid pressure, and 40 psi atomizing for a standard 5 foot coil line. If this does not provide adequate coverage, increase the fluid pressure until the desired 90% coverage is reached. Higher pressures may be needed for larger machines.
Extrusion Coil Lines: Using removable extrusion heads, set the fluid pressure to a setting that will provide a constant amount of adhesive to the sheet metal surface. Typical setting would be 30 psi fluid pressure. Higher pressures may be needed for increased number of extrusion heads.
- Painting
Allow Full cure. Use only latex or epoxy paint.
