Description

Cyanoethyl Starch is a chemically modified starch derivative where hydroxyl groups are substituted with cyanoethyl groups, significantly altering its physical and chemical properties. This modification enhances its solubility in organic solvents and imparts unique rheological and film-forming characteristics, making it a valuable specialty polymer. It is primarily utilized in advanced material science, serving as a key component in the formulation of adhesives, coatings, and specialty paper products for industries seeking performance-enhancing additives.

Application

• As a specialty binder and thickener in high-performance adhesive formulations, particularly for non-aqueous systems.
• Key component in the production of specialty paper coatings and sizings to improve strength, printability, and water resistance.
• Used in the formulation of dielectric materials and electronic coatings due to its film-forming properties and compatibility with other polymers.
• As a rheology modifier and stabilizer in certain industrial and cosmetic gel preparations.
• Intermediate in the synthesis of other functionalized starch derivatives for research and development purposes.
• Potential use as a controlled-release matrix in pharmaceutical and agrochemical applications.
