APPLICATION

NOPCOTE ENA152 Can be used in the surface treatment of paper and board in the size press either by itself or in combinatin with starch, CMC, PVAcohol or synthetic rubber.

NOPCOTE ENA 512 can improve the sizing degree, reduce the dusting, increase the dirnensional stability, improve offsetprintability. NOPCOTE ENA 512 can also be used as an additive in pigmented coatings. The product can improve block-resistance, modify the tack, improve the water resistance, prevent picking of the coating on drying and calender cylinders, reduce 'missing dots' in rotogravure printing and reduce the dusting of the coating.

DOSAGE

In surface size formulations (eg. in size press) together with starch, CMC, PVA]cohol or synthetic binder : 0.5 to 4.0% - as delivered - in relation to total surface-size solution. In -all surface size formulations addition of NOPCOTE ENA 512 should be after any cooking stage. Addition temperature should be less than 40"C

In pigmented coating colours : 0.25 - 2.0 parts wax dry on 100 parts dry pigment. NOPCOTE ENA 51 2 should be added near the end of batch make-down, phor to pH adjustment.

STORAGE AND HANDLING

Avoid excessive heat or cold. Ideally, product should be stored inside at between 10degree C and 35 degree C.
