Epoxy.com Product #301 is a 100% solids low viscosity epoxy adhesive used to
restore cracked structural concrete by the pressure injection method and to grout cracks
in a horizontal plane by gravity.
Low viscosity exceptional flow characteristics
Surface Preparation for Epoxy
Surface must be clean and sound. Interfaces of cracks must he free of dirt, laitance,
grease, curing compounds and other foreign matter. Flushing with water through ports under
pressure may he necessary prior to epoxy injection. Cracks may be damp or wet.
Epoxy Mixing Directions
Temperature of Epoxy.com Product #301 must he 40°F. or above at time of mixing. Stir each component separately before blending.
Best if used in an automatic binary mixing system. If mixed manually mix two
parts by volume of Part A with one part by volume of B for three minutes
with a low speed electric drill motor equipped with a mixing paddle.
Application Epoxy Injection Resin
For pressure injection set ports at intervals that approximately equal the
thickness of the member to be injected in inches. Ports may need to place closer
together for very fine cracks, or may be slightly further for wider cracks. Seal
between and around each port with Epoxy.com Product #5, or #6. Inject Product #301 from an epoxy
injection machine or binary hand or pneumatic injection gun. For more information consult
Epoxy.com technical service department.
Limitations of Epoxy Injection Resin
Minimum substrate temperature must be 40° F.
Cleaning Epoxy Injection Resin from Tools
All tools and equipment should be cleaned before the system gels.Use methyl
ethyl ketone or any lacquer solvent.
