KTR800

ACRYLIC CAULK KTR800
Duct Sealant for Air conditioning ducts

The acrylic sealant is fire-resistive, fibrated, water based, indoor/outdoor vapor barrier duct sealant for low, medium and high velocity heating and air conditioning ducts. It should perform as a tough and flexible adhesive and sealant, forming a durable seal against air leakage when used with or without reinforcing tape or membrane.
