Product/Package Notes:

PowerPatch® Transformer Leak Repair comes in several field-friendly forms.

PowerPatch® EPCT comes in a side-by-side cartridge (shown above) that mixes the two parts as they are applied. A plunger tool is required for application.

PowerPatch® EP is a thicker paste that comes in premeasured Part A and B cups. The two parts are hand mixed before application.

PowerPatch® EPSC is a slower-curing version recommended for large repairs where more pot life is needed.

The PowerPatch® Sealant is provided in kits with the preparation and patching materials necessary for a good repair. See details in the product table below.
