Product description


Aliphatic polyisocyanate (HDI biuret).

As the hardener component for lightfast polyurethane coating systems.

Solubility / thinnability
Desmodur® N 100 can be thinned with esters, ketones and aromatic
hydrocarbons such as ethyl acetate, butyl acetate, methoxypropyl acetate,
acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, toluene,
xylene, solvent naphtha® 100 and mixtures thereof. Generally speaking, it has
good compatibility with the solvents listed. However, the solutions formed must
be tested for their storage stability. Only PU grade solvents should be used
(max. 0.05 % water, absence of reactive groups such as hydroxyl or amino
groups). Aliphatic hydrocarbons are unsuitable as solvents.
Desmodur® N 100 should not be thinned to less than 40 % non-volatile content.
With time, lower binder content can lead to turbidity and sedimentation.

Compatibility
Generally speaking, Desmodur® N 100 can be mixed with the following
products: aliphatic polyisocyanates such as Desmodur® N 3200, ultra N 3300,
N 3400, N 3600 and Desmodur® Z 4470; aromatic polyisocyanates such
as Desmodur® L/ultra L, HL and IL/ultra IL; polyester polyols such as
Desmophen® 651 and 670; polyacrylates and polyether polyols such as
Desmophen® 1380 BT. However, the compatibility of the combinations used
should always be tested.

Storage
- Storage in original sealed Covestro container.
- Recommended storage temperature: 5 - 25 °C.
- Protect from moisture, heat and foreign material.
General information: The product is sensitive to moisture. Storage at higher
temperatures will result in increase of color and viscosity. Storage at significant
lower temperatures will result in solidification. This solidification is reversible
by briefly heating the product without adversely affecting the quality of the
product.


Storage time
Covestro represents that, for a period of nine 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 nine months period does not necessarily mean that the
product no longer meets specifications or the set values. However, prior to
using said product, Covestro recommends to test such a product if it still
meets the specifications or the set values. Covestro does not make any
representation regarding the product after the lapse of the nine months period
and Covestro 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 nine months
period.


Labeling and statutory requirements
This product data sheet is only valid in conjunction with the latest edition of the
corresponding Safety Data Sheet. Any updating of safety-relevant information
– in accordance with statutory requirements – will only be reflected in the Safety
Data Sheet, copies of which will be revised and distributed. Information relating
to the current classification and labeling, applications and processing methods
and further data relevant to safety can be found in the currently valid Safety
Data Sheet.


Further information
The product is used mainly as a hardener in coating materials or
adhesives. The handling of coating materials or adhesives containing reactive
polyisocyanates and residual monomeric HDI requires appropriate protective
measures referred to in the safety data sheet. These products may therefore
be used only in industrial or trade applications. They are not suitable for use
in homeworker (DIY) applications.

Applications


Desmodur® N 100 is used primarily as the hardener component for lightfast
two-pack polyurethane coatings with high resistance to chemicals and
weathering, very good gloss retention and outstanding mechanical properties.
Preferred co-reactants are polyacrylate or polyester polyols.
The main applications for systems based on Desmodur® N 100 are as air- and
force-drying coatings for automotive and industrial finishing, for wood, furniture
and plastics and for corrosion protection.
