Applications

Delta Duct Glue 81-10 is widely used in HVAC systems where fiberglass wool, glass wool, or similar insulation materials are bonded to interior or exterior surfaces of metal ducts. It is suitable for:

Bonding fiberglass or glass wool insulation to GI ducting
Bonding insulation to metal duct interiors
General-purpose ducting adhesive applications
Hot and humid climate HVAC installations

Method of Application

Apply Delta Duct Glue 81-10 evenly using a brush, roller, or pressure feeding equipment on both surfaces.
Allow the solvent to fully evaporate before bonding.
Assemble surfaces using normal hand pressure for effective adhesion.
For fibrous wool applications, apply adhesive evenly on the GI sheet and wait for 5–10 minutes before attaching the insulation. :contentReference[oaicite:2]{index=2}
