Vibra-Tite 989 Technical Data

Polyurethane Laminating

Product Data Sheet

Product De scription

Vibra-TITE 989 is a 1-component liquid adhesive
based on polyurethane. It is a moisture-curing,
medium open time structural assembly system.
Unlike contact adhesives, which require the coating
of both substrate surfaces, 989 requires only a single
side. There is no need for additional handling and
expensive drying ovens to flash off solvents before
engaging the bond. Standard packaging includes 5
gal. pails, 55 gal. drums, and Intermediate Bulk
Containers (275-330 gallon totes).

989 is designed to bond well to wood, lauan,
fiberboard (MDF), fiberglass reinforced plastic
(FRP), expanded polystyrene (EPS), polyurethane
foam, particleboard, high pressure laminate (HPL),
plywood, masonry, stone, ceramic and multiple
surface-treated metals and plastics.

Typical Applications

Interior & Exterior wall panels
Architectural panels
Insulated cooler and cold storage building walls
RV Motorized & Travel Trailer walls, roofs, & floors
Manufactured & Modular Housing construction
Residential & Commercial entry doors
Lamination of Structural Plastics
House boat composite wall lamination
Garage door section lamination

Procedure for Application

All bonding surfaces must be free of oil, grease, dust,
lubricants, and should be of sound quality. Remove
any surface contaminants with compressed air, brush
or solvents. Aluminum surfaces and certain other
metals must be epoxy/ conversion coated or primed
for best adhesion. Uncured adhesive can be removed
with solvents such as dibasic ester (DBE), propylene
carbonate, or citrus-based products. Cured adhesive
can be removed with recommended specialty
solvents or mechanically.

Storage

989 can be applied by roll coating, bead extruder, or
manually by hand. Recommended coating weights
will typically range between 10 and 20 grams/ ft²
depending on substrates used. Moisture is required to
efficiently cure the adhesive, usually 10% of the
applied weight of the adhesive is recommended.
Elevated temperatures will acce le rate adh es iv e
curing, and will reduce/ shorten open time. Intimate
contact pressure between the substrates is necessary
while adhesive is curing, 3 to 10 psi for soft core
materials, 50 psi for all other materials

989 should not be stored at temperatures above 85°F.
Properly stored in cool, dry conditions, the unopened
pails and drums have
