INSULATION ADHESIVE
Description:
Duro-Grip™ Insulation Adhesive is a two component
elastomeric polyurethane froth adhesive designed to adhere
both insulation and cover boards to various substrates. It can
also be used to adhere insulation boards together where
multiple layers are required.
Duro-Grip is applied in bead form directly to an approved
substrate. The “A” and “B” components are dispensed from two
pre-pressurized disposable cylinders using the hose and nozzle
kit. The insulation or cover board is placed onto the adhesive
and a chemical cure takes place several minutes after
application depending on temperature and weather conditions.
Duro-Grip contains less than 250 g/L of Volatile Organic
Compounds (VOC) and meets all VOC restrictions and
regulations in the United States. See Table 1 for VOC
information.
Duro-Grip is ideal for use when mechanical fastener penetration
into the roof deck is undesirable. Duro-Grip is approved for use
with many roof deck substrates, insulation and cover boards.
