How to Plate Bond in 10 Minutes

These are the alternatives to avoid the hazards of hot work and allow you to repair structures and equipment that maybe there is not enough material to weld.

Plate bonding is a cold-applied composite repair method where a metal plate is permanently bonded over damaged or weakened areas of equipment using high-performance composite repair materials.

Why choose plate bonding over welding?

Avoid Hot Work Hazards

No sparks, no flames, making it ideal for hazardous or flammable environments
Eliminates need for hot work permits

Minimize Downtime

Cold-applied, fast-curing systems get equipment back online faster
With USI’s training, maintenance teams can complete the work without bringing in a certified welder

Stronger than welds in many situations

Excellent adhesion and mechanical strength
Distributes stress across the bonded area without heat distortion
Non-corrosive

How it’s done – 5 Easy Steps

Surface Preparation – Substrate and Plate

Degrease the surface using a suitable solvent like USI’s Universal Cleaner to remove oil, grease and contaminants.
Mechanically abrade the area using an angle grinder fitted with a coarse pad or grinding disc. USI suggests a MBX bristle blaster for the best surface profile. You can also manually abrade the surface with a wire brush, sandpaper or metal file. Always follow the TDS for surface preparation.
Remove all loose debris and clean again with solvent to ensure a clean bonding surface.

Dry Fit Check

Position the plate over the damaged area and mark its placement
Ensure proper alignment, surface contact and accessibility for application

Product Mixing

Select the appropriate Resimac product based on the application (Resimetal 101, Resimetal 104 XF, Resimetal 106 XF)
Mix the base and activator thoroughly until a consistent color and texture are achieved in the trio on the TDS.

Application

Apply a uniform layer of mixed product to both the substrate and the back of the plate
Use a trowel or spatula to ensure even coverage and eliminate air pockets
Firmly press the plate into position, sliding slightly to seat the bond.

Clamping (if required)

Apply mechanical pressure using clamps, weights or magnets to hold the plate in place during cure (especially for vertical or overhead surfaces)
Maintain pressure according to cure time guidelines

Curing

Allow the repair to fully cure before returning to service
Cure time varies by product and environment but typically ranges from 6 to 24 hours
For faster returns to service, optional heat curing may be used if appropriate

Final Inspection

Verify bond integrity, inspect for gaps or voids, and test hardness (if required)
Optional: Apply a protective topcoat or corrosion-resistant finish. Resimac has many different overcoat protection options, each tailored to a different environment. Make sure to talk to a USI expert technical advisor to get the right coating for your environment.
