116
Product description
Vulkem
®
116 is a one-part, moisture-curing, gun-grade
polyurethane sealant. It is durable, flexible, and offers excellent
performance in dynamic joints.
Features and benefits
Vulkem 116 has demonstrated superior primerless adhesion
to porous substrates for 30 years, and is the choice for sealing
expansion joints in commercial construction applications.
Vulkem 116 is also suitable for certain water immersion
applications and is rated for 25% movement capability. The
cure of the sealant can be accelerated with the addition of the
Vulkem Catalyst 45/116.
Uses
Vulkem 116 is an excellent general-purpose sealant designed
for use on poured and precast concrete, masonry work, window
and door perimeters, and similar types of construction joints. It
is designed for use on exterior applications but can be used on
interior applications with proper ventilation.

Joint design
Vulkem 116 may be used in any vertical or horizontal joint
designed in accordance with accepted architectural/engineering
practices. Joint width should be 4 times anticipated movement,
but not less than 1/4” (6.4mm).
Joint backing
Closed cell or reticulated polyethylene backer rod is
recommended as joint backing to control sealant depth and
to ensure intimate contact of sealant with joint walls when
tooling. Where depth of joint will prevent the use of backer
rod, an adhesive backed polyethylene tape (bond breaker tape)
should be used to prevent three-sided adhesion. All backing
should be dry at time of sealant application.
