Today’s Resin

The Right Resin System for the Right Job

We want you to have the “Right Resin Product for the Right Job”, so we are always looking to improve our systems with new epoxy technology and new epoxy resin formulations. Today we are featuring a Methyl Methacrylate MMA not an epoxy.  We are not just about epoxy but we want you to have the right resin system for your job.

 

MMA Concrete Crack Healer and Sealer

684LV – MMA CONCRETE CRACK HEALER and SEALER replaces Epoxy.com Product #685.  MMA CONCRETE CRACK SEALER Product #684LV is a 100% reactive ultra-low viscosity methyl methacrylate resin used as a penetrating crack sealer or to fortify extremely porous concrete substrates. MMA CONCRETE CRACK SEALER Product #684LV is typically used on bridge decks, parking structures, and floors or as a general penetrating sealer to prevent moisture intrusion.

One of the major advantages of MMA CONCRETE CRACK SEALER Product #684LV is its very low viscosity.  It is about the viscosity (thickness) of diesel fuel, so it soaks into the concrete and down into small cracks quickly.  It hardens in about an hour.  When it hardens it hardens with a bond strength to clean concrete that is greater than the tensile strength of that concrete.  In other words you have just chemically welded the two sides of the crack together, so that it is as if the crack had never happened.

The very fast setting time allows you to install you flooring or sealer system the same day that you repair your crack. At Epoxy.com we are all about systems.  Combining the right resin product to create the right system for your job.
