Bayhydrol? A 2646
Solubility / thinnability The product issoluble in water.
Properties / Applications On account of itsoutstanding mechanical and
chemical resistance, the product is particularly
suitable for the formulation of hard, high-gloss
sealers for mineral substrates and reactive resins
(EP, PUR). Furthermore, excellent accentuation of
the grain of the substrate (e.g. colored coatings)
is achieved.
The binder can also be used for the formulation of
high-grade low VOC coatings for use on substrates
such as wood, metal, plastic, etc.
The product can also be combined with other water-
reducible binders. On account of the many potential
co-reactants, compatibility testing should always
be carried out.
The high reactivity enables short drying times,
which contribute to enhanced productivity.
The viscosity of the product is largely governed by
the pH. As the pH may decrease during storage, a
decrease in viscosity is also to be expected. The
viscosity can be restored to its original value by
the addition of small amounts of triethanol amine.
Dowanol? PnB and triethanolamine are OH-functional
cosolvents/amines that react with isocyanates. They
are therefore reactive thinners and not
VOC-relevant pursuant to the Decopaint Directive
2004-42-EC.
Storage - Storage in original sealed Bayer MaterialScience
containers.
- Recommended storage temperature: > 0 - 30 °C.
- Protect from frost, heat and foreign material.
General information: The product is sensitive to
frost. Prolonged freezing can damage the product
irreversibly. Prolonged storage at higher temperatures
may result in a decrease of viscosity and/or an
increase of average particle size, possibly resulting
in sedimentation or coagulation.
The viscosity of the product is largely governed by
the pH. As the pH may decrease during storage, a
decrease in viscosity is also to be expected. The
viscosity can be adjusted to its original value by
the addition of small amounts of an aqueous 10 %
solution of Triethanolamine.
Contamination with certain bacteria, fungi or algae
may render the product unusable.
Storagetime Bayer MaterialScience represents that, for a period
of six months following the day of shipment as stated
in the respective transport documents, the product
will meet the specifications or values set forth in
section "specifications or characteristic data" above,
what ever is applicable, provided that the product
is stored in full compliance with the storage
conditions set forth in and referenced under section
"storage" above and is otherwise handled appropriately.
The lapse of the six months period does notnecessarily
mean that the product no longer meets specifications or
the set values. However, prior to using said product,
Bayer MaterialScience recommends to test such a product
if it still meets the specifications or the set values.
Bayer MaterialScience does not make anyrepresentation
regarding the product after the lapse of the six
months period and Bayer MaterialScience shall not be
responsible or liable in any way for the product failing
to meet specifications or the set values after the
lapse of the six months period.
Safety Hazards identification
Not classified as a hazardous product as per Council
Directive 2006/121/EC or 1999/45/EC.
The safety data sheet should be observed. Thiscontains
information on labeling, transport and storage as well as
on handling, product safety and ecology.
