Frequently Asked Repair Adhesive Questions

Below are best practices on preparing two-component (2-part) adhesive and seam sealer cartridges for best results:

• Insert the cartridge into the dispensing gun with the proper mix ratio set up
  • When using 1:1 mix ratio cartridges of Fusor products, set the plunger for 1:1 cartridges
  • When using 2:1 mix ratio cartridges of Fusor products, set the plunger for 2:1 cartridges
  • Remove any cap and plugs
• Level the plungers by applying pressure to the gun until both sides of the material flow through the openings in the cartridge
• Attach the mix tip
  • Apply pressure to the gun forcing the material through the mix tip
  • Run out a mixer's length of adhesive on scrap material to ensure a complete mix
• Watch the video showing proper preparation of a two-part adhesive

Fusor products are tested with fully cured 2K (two-component) epoxy and 2K (two-component) urethane primers. Fusor products have not been tested with acid-etch primers.

Following are best practices for preparing Fusor Foam cartridges for best results:

• Remove any necessary panels and use a drop cloth to protect the surrounding area against accidental drippage.
• Remove cap from the Fusor foam cartridge and cut off the end of the cartridge tip.
• Insert the cartridge into a manual dispensing gun.  Note:  Due to the thin viscosity of the material, a pneumatic gun is not recommended.
• Holding the cartridge upright gently squeeze out a small amount of material to ensure that foam freely flows from both ends of the tube.
• Attach the mix tip.
• Apply a bead of Fusor foam between the vibrating panels or dispense a stream of material to fill a void.  Note:  When filling voids, build a dam to locate the foam where desired.
• Avoid dispensing material too quickly.  Foam will expand approximately 10 times its original volume to fill voids or eliminate vibration.
• Watch the Fusor Acoustical Foam Fill video.

Remove the mix tip immediately after usage and install supplied cartridge plugs to avoid pressure build-up.

Following are best practices for applying Fusor HD Sprayable Seam Sealers:

• Ensure the gun tip and nozzle are free of debris prior to spray application.
• Completely remove cartridge foil from the barrel bottom.
• Cut off the cartridge nipple at the extreme edge allowing most of the threads to be visible.
• Purge out any air prior to spraying by pushing in cartridge piston by hand until some product comes out.
• Tighten the gun barrel collars securely on both ends after cartridge insertion to prevent air leakage and spattering.
• Air pressures set between 25-40 psi (0.17-0.28 MPa) at the wall work best.
• Practice sprayable bead patterns before applying by spraying out on a scrap panel or cardboard.
• Start by adjusting the air control valve wheel from closed to slightly open, and then adjust as desired.  The fluid control can be adjusted for more product flow.
• To change a cartridge that has not been completely emptied, unscrew both collars and remove the barrel, and then slip the cartridge out of the barrel. Doing this eliminates the possibility of seam sealer leakage and prevents a mess inside the barrel.
   

Following are instructions and settings recommended for Fusor HD sprayable Seam Sealers:

• To apply a textured wheelhouse pattern or stone guard look, turn the airflow and hand-wheel counter clockwise approximately ½ turn and spray from a distance of 4-6 inches (10-15 cm) as desired.  The fluid control works well at about seven turns.  Adjust the air pressure at the line to 25 psi (o.17 MPa) for a narrow fan pattern and up to 40 psi (0.28MPa) for a wider spray pattern.  Adjust hand wheel as desired.
• For common floor seams, turn the airflow hand wheel counter clockwise approximately ¼ turn and spray from from a distance of ½-1 inch (1.302.5cm).  Adjust air pressure at the line to 40 psi (0.28 MPa) and set the fluid control knob to about seven turn.  Adjust hand-wheel as desired. Note: These are beginning settings - adjustment will be needed in your specific application.
• Watch our video.
   

Following are best practices for metal bonding with Fusor Adhesives:

• Grind the surface of all mating flanges (not greater than 1 inch (25.4mm) to which LORD Fusor metal bonding adhesive will be applied.
• Make sure to remove any adhesive, e-coating, corrosion protection or galvanized coating.  If metal has a pewter appearance, then not all of the galvanized coating has been removed.
• The metal should be shiny in appearance.
• Prefit the panel to ensure proper alignment.
• After the adhesive is applied to mating surfaces and panels are properly positioned, clamp the panels tight.  Glass beads in the adhesive will prevent over clamping.
• When bonding sectioning joints with the overlap technique, remove all excess adhesive from the sectioned area.  Check the sectioned area for a smooth transition to prevent ghost-lines after painting.  Skim coat the section seam with a fiber-filled body filler, rough sand, and blend with conventional body filler.
• Wait 8 hours before painting and baking.

Fusor 208B should be applied with the "buttering" method.  Apply a small amount of adhesive to the bonding flange of both panels. Quickly spread adhesive over all bare metal as a priming operation. This technique improves strength and ensures coverage of all bare metal flanges.

Watch the Fusor 208B video.
 

Yes. Rivet bonding is a method of joining metals which involves the installation of structural rivets used in conjunction/combination with a structural adhesive.

LORD Fusor 108B/109B and 112B/113B metal bonding adhesives are recommended to use for rivet bonding structural and non-structural body panels, depending on temperature and work time needed. Fusor 108B metal bonding adhesive is approved by Ford Motor Company for repairs on the 2015 Ford F-150 military-grade aluminum alloy cab by their dealers and independent body shops.

Procedure for Rivet Bonding with LORD Fusor Adhesives

For best results:

• Insert the coaxial cartridge into the #313 (manual) or #314 (pneumatic) rod driven dispensing gun. Pneumatic, non rod driven , 1K caulking guns should not be used. Cordless, battery powered, rod driven applicators are acceptable as well.
• Remove cap and plugs and level the plungers by applying pressure to the gun until both sides of the material flow through the openings in the cartridge
• Attach the mix tip
• Apply pressure to the gun forcing the material through the mix tip
• Run out a mixer's length of adhesive on scrap material to ensure a complete mix

If material has been in the mixing tube for longer than a half hour it should be replaced before applying adhesive to make a repair.

Fusor 2098 is not just strong, but tough. The tensile strength of the adhesive is similar to other high-quality aftermarket adhesives but when put into a peeling situation the toughness shows. Impact wedge peel, or IWP, is the measurement which illustrates this and Fusor 2098 provides 30N/mm (30 Newton millimeters) where most adhesives are in the 5-6 N/mm range. This is a tremendous increase and why it is so "tough". This toughness is why it is so crucial to replace all OE applied crash durable adhesives with Fusor 2098.
 

The 2098 bond removal is really no different than any other adhesive. Where a 2-T (2 "thicknesses" or layers of metal) overlap exists, use an electric heat gun to slightly soften the adhesive and then use a chisel action to break the adhesive bond. When a 3T or 4T panel overlap exists it is recommended to perform the removal cold as heat input could damage adhesive between the other layers.  Make sure to remove all old adhesive before installing the new panel and always check with the vehicle manufacturer for their position on use of heat.

Always follow manufactures repair guidelines for proper methods. Where no guidelines exist, duplicate the original OEM build process.

Fusor 2098 adhesive squeeze out can be painted after 48 hours room temperature cure or 2 hours of 140F° accelerated cure. To improve cycle time it is recommended to simply remove all squeeze out, wipe any adhesive residue from the surface using a solvent, and then apply a 2K sealer.

• Immediately - it may be welded immediately as there are no flammable vapors to flash off.
• 1-hour - while not critical, it is best practice to fully lock down the adhesive via the welding while in the work time window - after the hour point the STRSW will weld through the adhesive, but the ability to pull a tight bond line changes as the material may begin to harden.
