Foster® 32-17 SAFTEE™ DUCT SEALANT



FOSTER ® SAFETEETM DUCT SEALANT

Foster ® SafeteeTM Duct Sealant is a fire-resistive, fibrated water based, indoor/outdoor vapor barrier sealant for low, medium and high velocity heating and air conditioning ducts. It performs as a tough and flexible adhesive and sealant, forming a durable seal against air leakage when used with or without reinforcing tape or membrane. Mechanical fasteners of the type and number normally used for duct assemblies are required to provide rigidity to the duct system.

Safetee Duct Sealant has excellent weather resistance, low water vapor permeance and good water resistance, allowing it to be used outdoors and in high humidity environments. It is U.V. resistant. When dry, it may be painted with good quality water base paint.

Safetee Duct Sealant may be pressure tested within 16 hours dry time above 70ºF (21ºC) and below 60% RH. It quickly forms a strong bond to galvanized, aluminum or mild steel metal ducts. It has a mild odor when wet.

Safetee Duct Sealant will meet all SMACNA pressure classes up to 10" w.g. and SMACNA seal classes A, B, and C on ducts constructed to SMACNA standards. It has been tested up to 15" w.g. and passed with no sealant blow out.

Safetee Duct Sealant complies with current requirements regarding use in meat and poultry processing areas under federal inspection. Letter of compliance is available upon request.

Safetee Duct Sealant meets requirements for LEED IEQ 4.1 Low-Emitting Materials, Adhesives and Sealants. VOC: 45 g/l, less water and exempt solvents.

LIMITATIONS
Store and apply between 40ºF (4ºC) and 100ºF (38ºC), protect from freezing until dry. To resist rain washoff, allow at least 12-15 hours drying time above 40ºF (4ºC), with a relative humidity of 50%. Higher humidity or lower temperatures may retard drying. Always test foil and paper facings for acceptable adhesion. Outdoor horizontal surfaces must always drain completely. At pitch of at least 1/2 inch per foot (4cm/m) is required. If used between impermeable surfaces, drying time will be extended. TM TradeMark of H.B. Fuller Construction Products Inc.
