FIELDS OF APPLICATION
Sintoren 204 is generally applied to the paper surface together with
starch. The result of application is increased tear strength, reduction
of dust production and better printing properties.
These effects are particularly marked for office and administration
papers.
As an amphoteric surface sizing agent Sintoren 204 is primarily
characterised by the following properties:
-usable over a wide pH (3-10) range
-compatible with a large number of cationic and non ionic additives
(basic dyes, cationic starches, PVA)
-supports the effect of optical brighteners
-high tolerance of electrolytes
-also effective in impurity loaded size press circulations
-low tendency to foam.
Sintoren204 is very effective on raw papers manufactured from both acid
and neutral stocks. The addition of aluminium sulphate to the paper pulp
is not necessary but does not interfere. There are no problems in using
chalk as a filler for the paper mass.
The amount applied is 0,5 - 2,5 % Sintoren 204 respect to oven-dried
paper depending on the raw paper, presizing of the mass and the size
value required. The optimal amount and working conditions should be
determined by machine trials.
DELIVERY FORM AND SAFETY MEASURES
Sintoren 204 may be delivered in drums, 1000 kg container or
tanks. In the handling of Sintoren 204 avoid contact with eyes,
skin, mucous membranes and wounds. Wear gloves and goggles and follow
other instruction contained in the safety data sheet.
STORAGE
Sintoren 204 can be stored at temperatures between + 2°C and + 30°C
for at least 6 months. Protect from frost
