Yellow Dextrin

Dextrins 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.
Description: -
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.
Applications:-
Adhesive Industries:
The Adhesives Industries uses large amount of yellow dextrin in the preparation of liquid
and dry adhesives. Dextrin goes in to the solution instantly and with a lesser quantity of
water, because of their greater adhesive strength and fluidity.
Dextrin is widely used in the manufacture of:-
Spiral convolute tubes.
Carbon paper manufacturing, abrasive and in dry distemper.
Machine labeling of tins cartoon packages envelop corrugated boxes.
Also used by crackers manufacture due to adhesives properties & also explosive character
In Paper tubes and paper cones.
In book binding cartoon sealing pasting match head and matchbox making.
As core binder in Refractory and foundry operations.
Chemical & Dyes Industries
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
Foundries
Yellow dextrin serves as an excellent binding agent for sand cores in foundry operations
