Introduction
PRINTBOND-50 increases the strength properties of board / paper and decreases the air permeability to a greater extent than a film of starch alone at the paper surface. Although it is not added in the wet end, it has a close relation and interaction with wet end additives. Like any wet end sizing agent, it reduces the tendency of water to penetrate into paper.
PRINTBOND-50 is very effective in a wide pH range i.e. for acidic, neutral or alkaline base paper. Its effectiveness greatly improves if the paper has enough internal sizing.
PRINTBOND-50 can be used conveniently in combination with other surface sizing additives. All these features make PRINTBOND-50 a great spray additive to achieve:
1. Increase internal strength properties
2. Excellent improvement in sizing, resulting in reduced sizing chemical consumption in wet end
3. Increase stiffness
4. Improved ply-bond adhesion
