INTRODUCTION
"OXISTAR-HC"
is
a chlorine-free oxidised starch, developed for use in the size press and
paper coating formulations. It is from the house having unrivalled
experience in the field of manufacturing and supplying Spray Starches
viz. “DS-HIBURST” and “DS-HIBOND” as well as high quality
cationic starches “DS-CATSTAR”. Carboxylic groups make the paste of
the product more stable to retrogradation. Its paste is relatively
clearer and more fluid for better film formation. OXISTAR-HC has better
water holding capacity and films are stronger. Its use intensifies
following:
- Improved printability
and better print ink holding.
- Better surface
strength, wax pick resistance, smoothness, brightness retention
compated to DS-OXISTAR.
- Better surface sizing
/ pigmenting due to excellent film forming.
- More consistent results due
to control on viscosity.
PRODUCT DESCRIPTION
Paste
made from “OXISTAR-HC” has a greater degree of fluidity. When
compared to DS-OXISTAR, the film
produced from OXISTAR-HC is continuous and strongly adhesent.
APPLICATION
At size press for
surface sizing / additive for coating

HANDLING, STORAGE
& SAMPLING
Please take
following care during handling, storage and sampling :
- Do not use hooks, drag
the bags on truck or any other platform.
- Make sure that
unloading labour have clean hands and heads covered
with clean
cloth/cap.
- Bags should be stored
on clean platform, kept covered with
clean piece of tarpaulin. Also ensure that storage area is dry,
covered, away from humid conditions, hazardous, explosive and
aromatic chemicals.
GENERAL INFORMATION
1) In order to get the
best performance, it is recommended to store the bags in
covered dry space.
2) Shelf life, if stored properly, can be as high as 1 year.
