Please clean the surface where PLASEAL NF-23 will be
constructed, and be free of water and dust.
NITTO CHEMICAL INDUSTRY CO.,LTD.
Application Procedure①
Please construct NF-23 so that any cables do not touch
rectangular / circular coaming.
If a cable needs to be spaced from any other cables or
rectangular /circular coaming, spacer can be used to make
space.
Metal parts can be used at the deck division for ease in
construction.

Application Procedure②
-
Please construct NF-23 without any space, especially at the
surrounding of any cables.( For example, a stick or suitable
instrument can be used in order not to make any space. )
Fill with PLASEAL NF-23 up to the edge of rectangular / circular
coaming and cover the surface of edge with it.
Total area of several bundled cables should be as follows or
less.For rectangular coaming approx.105㎜×365㎜ ( height×width )For
circular coaming approx.105㎜×110㎜ ( height×width )
NITTO CHEMICAL INDUSTRY CO.,LTD.
Application Procedure③
Notes・Since PLASEAL NF-23 is a dry-hardening type putty
(fire-resistant putty）,
it should start hardening from the applied surface. Please make
sure that it might take several months for fully hardening based on
applied thickness, temperature and humidity.It should still have
high fire-resistant performance even though the applied putty
hasn’t fully hardened yet.(When you apply 100㎜ of PLASEAL NF-23 to
φ130 at an ambient temperature of 20 degrees C / humidity of 65％,
it takes about a month for hardening of 10㎜ from the applied
surface, and about 4 months for fully hardening.)
・The warranty period for PLASEAL NF-23 is 6 months after
production, and is valid if products remain sealed and are stored
at room temperature avoiding direct sunlight.
・Avoid using PLASEAL NF-23 outdoors and in a place where water
splashes directly.
・It is recommended to use some waterproof sealing materials or
coating materials like NAICOAT SB-61(waterproof type ; Nitto
chemical Industry co.,ltd. ) at high humidity area in order to
cover the surface of PLASEAL NF-23 from moisture. (If it is exposed
under high humidity for a long time, this might cause dripping and
seeping from the surface.)
