EPOXY PATCH ADDITIVE
What is Epoxy Patch Additive?
UDT Epoxy Patch additive is a very fine powder that is added to epoxy coatings (MC and MC-UV Epoxy) during the mixing process to achieve a thick-viscosity patching material.
Protecting Your Health
UDT Patch Additive contains <1% silica and is formulated to release a minimal amount of silica dust into the air during the mixing process. This is important because it dramatically reduces occupational exposure to crystalline silica dust that may be associated with an increased risk for pulmonary diseases such as silicosis, tuberculosis, chronic bronchitis, chronic obstructive pulmonary disease (COPD) and lung cancer.
Directions
Mixing:
Determine quantity of UDT Epoxy Patch Additive (Patch) to prepare based on the application.
For larger holes and expansion joints, mix at 2:3 ratio (Add 2 parts Patch to 3 parts mixed MC-Epoxy). The result of this mixture will be a thick paste that largely resists sagging in large voids.
For shallow cracks and spalls, mix at 1:3 ratio (Add 1 part Patch to 3 parts mixed MC-Epoxy). The result of this mixture will be a thin, glue-like paste.
Fill a measuring cup with the desired amount of Patch. Do not pack the patch material down when measuring.
Begin mixing the MC Epoxy at the normal ratio (2 Parts A to 1 Part B).
After mixing the epoxy for 1 minute, add the Patch Additive and continue mixing for an additional 2 minutes.
It is recommended to mix only the amount of Patch material that can be applied within 5-10 minutes.
Thinner Patch (1:3 ratio) will be usable for approximately 10-15 minutes.
Thicker Patch (2:3 ratio) sets up faster and will be usable for approximately 5-10 minutes.
Application:
Immediately begin applying mixed Patch material to the floor with a flat, metal trowel or putty knife. Pour or push the Patch material into holes and then scrape excess material from the surface. Allow Patch to dry thoroughly before grinding or sanding. If sanding or grinding is not needed, proceed to mixing and applying subsequent coating(s).
