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

fiber, 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-filled 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.
