INFORMATION
White Dextrins have a appearance of the native starch
and have solubilities varying from 25-80%. It forms
a soft, light coloured get on cooling.Yellow Dextrins
ranges in colour from pale amber to dark brown and have
high water solubility. They are used to produce high
solid concentration pastes. They give very tacky solutions.

| APPLICATIONS |
| I |
Dextrins do not reacts with Chemicals. They are
very much useful and play important role to various
Industries.
|
| II |
Textile Industries: In textile printing
dextrins are used as thickner,Copper rolls get
long life in sizing and increases, adhesiveness
in finishing. They give desires feel to the fabric.
|
| III |
Dyes: Dyestuff industry is used as a
extenders.
|
| Iv |
Pharmaceuticals: Dextrains are used as
a neutrient source in preparations of certain antibiotics.
|
| V |
Foundries : For good care binding as a
binder, it imparts great compressive strength. To
give good strength to moulds and to prevent deformation
of the core. They do not make the core too dense.
So there are no trapped gases which cause blowholes.
|
| VI |
Dry Distemper : Dextrins are largely used
in dry distemper 2 to 3 % of Dextrins with chalk
and pigments act as a carrier and impart good
adhesiveness of colour to the wall.
|
| VII |
Grinding Wheel: Binder for different constituents
forgrinding wheel. Dextrin are also used a binder
for water colour Mineral aggregates, ink colour
binder, laminates, fibers paper bags & boxes,
paper tubes and cones, postage stamp, gum tape,
fireworks, cigarettes Crayons, polishing dyes. Leather
linoleum wall paper in silvering compounds and so
many other industries use dextrin. |
