Royal-Bond is an additive that is added at the size press starch solution to improve the hydrogen bonding and further improving the paper strength. It can lead to reduced usage of starch as we all are aware that excessive use of starch leads to various unwanted issues.
In papermaking, size press plays a very important role. Over the years, its utility has become more than just surface sizing. Different additives are added at this point to improve upon various paper properties. These properties can be internal sizing (Cobb), shade, stiffness, smoothness etc.
Royal-Bond is very cost effective and is compatible with all the chemicals used in papermaking. It has chemical functional groups that enhance ‘fibre-to- fibre’ and ‘starch- to- fibre’ bonding. Its typical application of 0.15 to 0.30% leads to: improvement of Bursting Strength beyond what can be achieved by starch alone, Improves internal bonding and surface-bond strength including RCT/CMT, Improved stiffness
