PIR Duct Adhesive is inflammable, one component adhesive based on Synthetic with special tackifier and additives. It is specially developed for polyurethane and polyisocyanurate (PIR) foam in air duct system. It is very good in film forming nature which gives uniform bonding to most of substrate like cross-linked polyethylene, EPDM & similar substrate.
It is a Synthetic rubber based Adhesive and has excellent wet tack and excellent Adhesion and High Strength with Phenolic Vs Phenolic, PIR v/s PIR & PU v/s PU. It is excellent bonding to Porous and Non Porous Surface and has very high Resistance to Heat and Chemicals.

In HVAC system assembly, HVAC Adhesives are beneficial instead of welding in improving the manufacturing processes in many of the industrial use cases. HVAC adhesives are used in low pressure molding, metal surface treatments, insulation bonding, elastomeric sealants and machinery adhesives applications.
