DURO-GRIP CR-20 INSULATION ADHESIVE

DESCRIPTION:
®
Duro-Grip CR-20 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.
CR-20 is applied in bead form directly to an
approved substrate. The “A” and “B” components
are dispensed from two pre-pressurized disposable
tanks 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.
A/B Tank Kit, Hose/Gun Kit, Wrench and Nozzles
CR-20 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.
CR-20 is ideal for use when mechanical fastener
penetration into the roof deck is undesirable. CR-20
is approved for use with many roof deck substrates,
insulation and cover boards.
