WESCAT®
Cationic potato, quaternary amine, high-performance wet-end starches.
WESCAT® provides performance chemical characteristics in a modified starch.
Successful applications of WESCAT® starches include:
- Fine papers: Retention of fillers and fines, mechanical dry strength properties.
- Kraft paper for bags: Mechanical dry strength properties, porosity and dewatering.
- Kraft liner: Mechanical dry strength properties, retention and dewatering, internal bond.
- Board: Retention of fines, dewatering, internal bond.
- Newsprint: Mechanical dry strength, surface strength (linting, picking).
 Additional Properties of WESCAT® starches:
WESCAT®
is a potato starch derivative which was developed to increase the
retention of fillers and fines and/or increase the mechanical dry
strength properties of paper and board. Potato starches have natural
phosphate groups that cereal starches lack. This gives WESCAT® starches
a natural amphoteric conformation.
WESCAT® is a quaternary
amine cationic starch that retains its effectiveness over a large pH
range making it very beneficial for use in acid, neutral, and alkali
paper making.
WESCAT® retains all types of fillers, such as clays, titanium dioxide, carbonates, sulphates, etc.
WESCAT® starches work especially well in ASA size emulsification applications due to the tight control of viscosity available.
WESCAT®
starches are custom made for each customer's application. Our sales and
service personnel work closely with mills and their chemical vendors to
optimize the wet end starch for each paper making application.
WESCAT®
is available in low nitrogen to high nitrogen, low viscosity to high
viscosity depending on the needs of individual mills or paper machines.
WESCAT® cationic potato starches are solving problems in paper
mills. If you have a need for a superior wet-end starch, please
contact our experienced sales or service departments. |

The molecular weight of the potato amylose molecule is five times greater than that of corn.
A higher Molecular weight provides better bonding and lower retrogradation rates.
Enhanced bonding strength is the primary benefit of using potato starch over cornstarch.
In many applications, potato starch is the better choice!
