LORD Fusor
®
117 Plastic to Metal Cross Bonding
Adhesive
(Slow)
LORD Fusor
®
117 plastic to metal cross bonding adhe-
sive is formulated to bond plastics such as SMC, carbon
fi ber, Metton
®
, fi berglass, ABS, polycarbonate, acrylic,
etc., to bare metal. It can also be used for plastic-to-
plastic bonding and metal-to-metal bonding.
Usage
Metal Preparation
1. Grind the surface of all mating fl anges (not greater
than 1 inch [25.4 mm]) to which LORD Fusor cross
bonding adhesive will be applied. Make sure to
remove any adhesive, e-coating, corrosion protection
or galvanized coating. If metal has a pewter appear-
ance, then not all of the galvanized coating has
been removed. The metal should be shiny in appear-
ance. If sectioning, the seam will need a 10° bevel
for a smooth transition into the existing panel (see
Illustration A).
2. Pre-fi t the new panel to ensure proper alignment.
Plastic Preparation
1. Clean the area to be bonded with plastic & rubber
cleaner.
2. Sand the bond areas with 80-grit sandpaper.
Product Preparation
1. Remove the cap and nose plug from the LORD Fusor
cross bonding adhesive.
2. Insert the LORD Fusor two-component adhesive
cartridge into the dispensing gun.
3. Squeeze a small amount of LORD Fusor cross
bonding adhesive from each side of the cartridge.
This will level the plungers and ensure that adhesive
is coming out of both sides of the cartridge.
4. Attach the mixing tip and dispense a small amount of
material, which is about the width and length of the
mixer, to verify that the adhesive is evenly mixed and
that the color is consistent.
Application
1. Apply a 3/8 to 1/2 inch (9.5 to 12.7 mm) bead of
LORD Fusor cross bonding adhesive to the prepared
mating surfaces (see Illustration B).
2. Secure the panel using clamps. Apply screws or
rivets in hard-to-clamp areas. After the panel has
been positioned, do not pull it away from the vehicle.
If repositioning is necessary, slide the panels against
one another. This maintains contact between the two
surfaces.
3. Allow adhesive to cure 1 to 1-1/2 hours before
unclamping. Remove all excess adhesive from the
sectioned area. It is critical to check the sectioned
area for a smooth transition to prevent ghost-lines
after painting. If necessary, additional grinding can
be done to ensure a smooth seam. Skim-coat the
section seam with fi ber-fi lled body fi ller, rough sand,
and blend with conventional body fi ller. Wait 8 hours
before painting and baking.
4. The adhesive will be a little “tacky” on the surface
after full cure. This is a normal property of the
adhesive.
5. Remove the mixing tip after usage and reinstall
the nose plug and cap to avoid adhesive cross
contamination.
