| NOPCOTE C-104 |
Paper coating Lubricant |
| NOPCOTE C-104 is a
liquid, 50% solids calcium stearate dispersion for
use in starch, protein or latex coatings. It improves
the application of coating and imparts a superior
finish to coated paper. Among its outstanding features
are its economy and case of use.
By lubricating the coating, NOPCOTE C-104
improves flow and levelling characteristics, making
possible smooth, even application. It also plasticises
the dry coating and improves its printabildy, gloss
and smoothness.
Like all NOPCOTE calcium stearate
dispersions, NOPCOTE C-104 has
a small average particae size to provide mayimum
dispersion stability. It also gives low residue
levels on a 325 mesh screen.
NOPCOTE C-104 prevents dusting
at the supercalenders and during slitting and printing
operations, resulting in higher operating speeds
In certain grades of paper, superealendering can
be omitted, since NOPCOTE C-104
gives a high finish with machine calenders alone. |

APPLICATION
NOPCOTE C-104 is normally used at
a level of 0.5 - 1.5 % on the weight of the dry solids
in the coating. Being a mobile liquid, no predispersion
is necessary. It may be mixed directly with the coating
colour at any convenient point in the make-down of
the colour. When starch is the adhesive, however,
it should not be added until the starch has been cooked.
NOPCOTE C-104 dispersion is stable
in the presence of alkalis and dilute acid solutions.
It should not be subjected to strong acid solutions,
since decomposition of the calcium stearate will
result.. |

PACKAGE,
STORAGE AND HANDLING
NOPCOTE C-104 dispersion is shipped
in 200 litre lined steel or plastic drums or 1000
litre plastic cage containers. The product can also
be shipped in bulk road tankers. Storage of the bulk
material should be in tanks which can be stirred.
Freezing seriously damages the product. Protect against
low temperatures in storage. Containers should be
kept tightly closed when not in use to avoid evaporation
losses.
In hot climates, the product should be stored in
the shade and, preferably, inside a building.
Additional handling information is contained in
a material safety data sheet which is available
on request. |
