Adhesives & Binders
Dextrin are prepared by heat treatment in presence of chemicals to suitably modify characteristics and properties of starch. They find application in dyes, adhesives, foundries, fire-crackers, oil drilling and many other industries.
Unlike starch dextrin are soluble in water. The severity of the treatment determines the degree of solubility, which is the basis of classifying or grading dextrin. Finished dextrin are very fine powder varying in color from pure white to yellow to dark brown.
|Appearance||White / Cream White|
|Moisture soluble||10 to 12|
|pH||2.5 to 3.0|
|Acidity for 5gms using NaOH||1.00ml|
|Mesh size-pass through 85 mesh||99.80|
|Soluble||50 to 60|
It is widely used in the manufacture of:
The advantage of dextrin in the dye stuff industries are so well recognized that good many large scale manufactures have taken to using highly soluble dextrin as diluents to standardized the dyes with respect to the range of color. Dextrin washes out quickly and easily and do not react with chemicals used in the process.
