DESCRIPTION
BOSS® 350 Flame Retardant Duct Sealant is high performance, flame retardant duct sealant designed for use in high, medium or low velocity heating and air conditioning systems. BOSS® 350 provides excellent strength, flexibility and resistance to heat and cold, forming a seal against air leakage. BOSS® 350 Flame Retardant Duct Sealant cures to a tough, tackfree, flexible sealant and remains flexible at low and high temperatures. Do not apply below 40°F (4.4°C). Do not thin. Use in conjunction with metal fasteners to hold assembly together
HOW TO USE
BOSS® 350 Flame Retardant Duct Sealant should only be used where slight joint movement is anticipated. In extremely deep joints, use foam joint filler. Tooling is recommended and, if possible, should be completed in one continuous stroke. Tool joints within ten minutes of application. If masking tape has been used to obtain a cleaner joint it should be removed before the tack-free skin forms.
CAUTION:
Do not apply when building material or air temperature is below 40°F (4.4°C). BOSS® 350 is not recommended for continuous water immersion.
