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

NOPCOTE 1661 is packaged in 200 litre Polythene lined drums net 250 kg weight, Although freezing does not damage the product, it is recommended that inside storage with a minimum 5 degree C temperature be used.

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.
