The Main Data:
Product Name: Water Repellent Agent for coating(PAPU)
Appearance: Colorless to pale yellow transparent liquid Effective Matter Content: a water soluble polyamide epoxy resin
The Main Description:
It is suitable for high-speed paper coating machine. It can be crosslinked with protein adhesive and starch adhesive. At the same time, it can also be self crosslinked to form a film with good water resistance. The film has certain flexibility and wet strength, so it can be widely used in offset printing coating adhesive (copperplate paper) and coated white board paper.
At the same time, it can also be used in the paper surface sizing agent to improve the surface strength of the paper. After coating on the paper, cross-linking occurs in the drying process with high temperature, which makes the coating obtain good wet friction resistance.
The Advantages:
- Low viscosity.
-Formaldehyde-free, ammonia-free.
-Crosslink rapidly, good water resistance without curling, suitable for coating recipe with starch.
