Formaldehyde Free Coating Insolubiliser |
Formaidehyde Free Coating
lnsolubiliser NOPCOTE 1661 is a formaldehyde free
coating insolubiliser for application in all pigmented
paper coatings. NOPCOTE 1661 provides maximum wet-rub
and wet-pick resistance by reducing the water solubility
of coating binders. NOPCOTE 1661 is formaldehyde free,
ensuring freedom from noxious and potentially harmful
fumes during curing and drying.
ADVANTAGES
- Formaldehyde
free reduces potential health risks and provides
case of storage and handling.
-
Cost effective vs. Formaldehyde resins and competitive
formaldehyde free resins.
-
Does not increase viscosity of starchbound,coatings
- More
rapid cure at lower temperatures vs. Formaldehyde
resins.
-
Light colour with no residual formaldehyde odour.
-
Provides maximum wet-rub resistance vs. Formaldehyde
resin and competitive formaldehyde free resins.

APPLICATION
To ensure desired wet rub resistance, NOPCOTE
1661 should be added at approximately 20%
of the known requirement for M.F. resin, on a solids
basis. For new applications, the approximate addition
level is 2.5 - 5 % NOPCOTE 1661
on coating binder solids.
NOPCOTE 1661 should be added to
the coating makedown following the addition of all
binders.
NOPCOTE 1661 cures during drying
of the coating. Wet rub resistance can be expected
off the driers with maximum resistance in 24 hours. |
PACKAGE,
STORAGE AND HANDLING
