Applications & Uses

Limitations

• Systems may be pressure-tested 36 hours after application, above 60°F (16°C).
• Make certain this product is completely dry and the area free from solvent odor if food is involved.

Preparation and Application Information

Material preparation

• Do not thin.
• Stir well, but do not use sticks or boards w hich w ould splinter or otherw ise contaminate the product.
• Apply only to clean, dry, oil-free surfaces.
• Keep container closed w hen not in use.

Application 

• Apply by brush or extrusion.
• Brush: On spiral duct, apply a thick coat of 32-14 to the male end of the coupling prior to slipping the straight run of spiral duct over it. Brush excess 32-14 over the exterior of the joint and over the heads of all metal screw s after they are in place and the joint is mechanically fastened. On the flanges of rectangular ducts, both flange faces should receive a coat of 32-14 before joining w ith the flange gasket. Join and bond w hile sealant is still w et (0 – 3 min.). If the material should skin on the surface after application, this may be broken by a slight tw isting action of the metal duct or a fresh application over the first coat.
• Power extrusion: High velocity duct sealant may be applied using a w ide variety of power (pressure) extrusion equipment suitable for use w ith solvent-based sealants. Average viscosity: 100,000 – 150,000 cps. (Brookfield).

Cleaning Information : Use a solvent such as chlorinated solvent (non-flammable) or mineral spirits (flammable) for cleaning tools and equipment.

Features & Benefits

Product Highlights

• Foster® High Velocity Duct Sealant 32-14 is a fast setting, elastomeric compound designed as a joint sealant for high velocity air conditioning ducts installed indoors.
• It may be used with or without reinforcing tapes. It has a mild “paint type” odor and applies cleanly without stringing. Mechanical fasteners of the type and number normally used for duct assemblies are required to provide rigidity to the duct system.
• Foster® High Velocity Duct Sealant 32-14T can be used to adhere duct fabrics and flexible tubing runouts to high velocity ducts and to mixing boxes or air diffuser heads.
