Epoxy.com Product #3301 is a 2-component, low viscosity, 100% solids, epoxy injection resin for concrete and wooden substrates.
Epoxy.com Product #3301 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.
Surface must be clean and sound. Interfaces of cracks must be 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.
Temperature of Product #3301 must be 60°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.
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 Product #2005, or #2006. Inject Product #3301 from an epoxy injection machine or binary hand or pneumatic injection gun. For more information consult Epoxy.com� technical service department.
Minimum substrate temperature must be 50° F.
All tools and equipment should be cleaned before the system gels. Use methyl ethyl ketone or any lacquer solvent.
This is a solvent free and Nonyl Phenol free product, and practically odorless during application. Follow the appropriate Occupational Health and Safety guidelines applicable to the location where the application is undertaken. For more information, please refer to the safety datasheets for the individual components.
2 parts of component A are mixed with 1 part of component B, by volume.
Add Hardener B to Base A. Mix with slow speed drill and appropriate mixing paddle taking care not to entrain air. May also be mixed by appropriate static mix tube.
The recommended substrate temperature is 60° - 80°F, but no less than 50°F.
Mixed product should be used within 40 minutes at a temperature of 70°F. At higher temperatures the application time is shorter.
Approximately 12 hours. The product is fully hardened after 5 - 7 days.
