Compatibility: Compatible to the pigment and additive that in the application of coated paper and paperboard

Application: XSB-Latex PC-798A is the mid to higher hardness latex, the modified formula from PC-798, where applied in the top coat of the coated paper, can provide the anti speckle print property, higher bond strength, also can enhance the paper stiffness and gloss based on the good ink absorbency.
The coating should adjust in the alkalescence before adding PC-798. Please avoiding the excessive sheer force during dispersion.

Storage: The products should be storage in the temperature of 6 – 30°C with good ventilation. The storage life is 6 month since the production date.

Package: XSB-Latex has three kind of packaging:
Plastic drum: 200 KG
Cubic plastic drum with discharge hole: 1000 KG
Tank truck

Transportation:
All the XSB-Latex transportation should be handled with care and prevent inversion.

3. Other items should pay attention:
1). The XSB-Latex can not be stirred if the latex temperature below 6°C, for which should be stirred after the temperature slowly increased.
2). If the latex frozen, please increase its temperature slowly, so can be in normal application when most of the latex dissolved.
3). Please avoid the contact with polyvalent ion, which will cause the emulsion breaking.
4). Please avoid the mix with strong acid alkali.
5). Strongly avoid the mix with cation gum rosin that is the additive in the paper making, this will destroy the emulsion stability.
