(4) Applying resin
CAUTION: Observe the following precautions when applying epoxy resin during floor-
leveling work.
• Good ventilation must be provided since the epoxy resin is a volatile
chemical.
• This job must be performed with a plastic floor-covering sheet laid on
the floor.
• Gloves, eye protection, etc. must be worn when handling the resin.
• Before mixing the liquid agents, they must be accurately weighed using
an oil replenishment container.
• The oil replenishment container that has been used for weighing must
not be used to apply the resin.
1. Place the epoxy resin (main agent) and the diluent into a basin and mix them
thoroughly. It is recommended that an electric mixer be used for mixing because
the viscosity of Epichlon 830 (main agent) is higher than that of Epichlon 857. After
thoroughly mixing the epoxy resin and the diluent, add the hardener and the
pigment and mix thoroughly again. The proportions of the components in the
mixture should be as follows:
Mixture proportions (by weight) : Epoxy resin (Epichlon 830)
2. Pour the liquid mixture into the frames.
Since the resin has a certain degree of viscosity, the mixture must be poured
evenly. The amount of mixture poured should be such that the minimum thickness
of the resin is about 5 mm.
3. Allow about one hour after the start of pouring to observe closely for leakage of the
resin from the frames. If leakage is seen, immediately seal the leak using adhesive
tape or caulking compound (joint sealant).
4. After pouring has been completed, apply a spray lubricant CRC-556 to the epoxy
resin surface. This eliminates any bubbles from the resin surface to ensure a
smooth finish.
(5) Finishing the resin surface
1. After allowing the resin to stand for 48 hours or more, check that the surface has
become hard (press the surface with a push-pull gauge and confirm that the surface
is not dented).
2. Remove the frames. Remove the gantry-to-couch epoxy resin passageway using a
saw.
3. Remove any rough edges or bulges from the corners and the surface using a
grinder. Finish the entire surface so that it is flat and smooth.
