Yellow Dextrin By Shubham Starch Chem (P) Ltd.

Yellow Dextrins are prepared by roasting starch in the presence of acid, which chemically changes the character and properties of starch. They are intermediate between starch and sugars derived from starch. They are starch converted products, which find applications in dyes, adhesives, foundries and other industries.

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.

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. It gives high green bond strength necessary for the mould to remain intact during handling.

Color Industries

Dextrin is largely used in dry distemper. five to ten % of dextrin, mixed with chalk and pigment, acts as carrier and impact good adhesion of the color to the wall.
