Temperature of Product #3899 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.
Application Epoxy Primer
Apply by brush, roller or squeegy at a rate of 250-300 SF per square foot.
For more information consult Epoxy.com technical service department.
Limitations of Epoxy Injection Resin
Minimum substrate temperature must be 50° 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.
Environment & Health
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.
Ratio of 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.
Application Temperature
The recommended substrate temperature is 60° - 80°F, but no less than 50°F.
