WANNATER HT-100 is a solvent free aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI), colorless to slightly
yellowish clear liquid.
Equivalent weight approx. 193
Density at 25 approx. 1.16 g/ml
Flash point approx. 158
WANNATER HT-100 can be used as the hardener component for lightfast
two-component polyurethane coatings with high resistance to
chemicals and weathering, very good gloss retention and outstanding
Preferred co-reactants are polyacrylates or polyester polyols.
The main applications for coatings based on WANNATER HT-100 are
automotive OEM, automotive refinishing, transportation, industrial
finishing and plastics.

Storage / Solubility
Storage in original container. Protect from moisture, heat and
WANNATER HT-100 is sensitive to moisture. Storage at higher
temperatures will result in increasing of color and viscosity.
Recommended storage temperature is -20 ~ 40 C.
WANNATER HT-100 can be thinned with esters, ketones and aromatic
hydrocarbons such as ethyl acetate, butyl acetate,
methoxypropylacetate, 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

WANNATER HT-100 is not recommended to thin to a lower solid
content. Prolonged storage of a solution with a lower content may
result in turbidity and sedimentation, even condensation.
WANNATER HT-100 can be mixed with the following products: aliphatic
polyisocyanates, polyester polyols, aromatic polyisocyanates and
It can be stored at least for 9 months at room temperature if
Safety Hazards identification
May cause sensitization by skin contact. Contains isocyanates. See
information supplied by the manufacturer.
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
The safety data sheet should be observed. This contains information
on labeling, transport and storage as well as on handing, product
safety and ecology.
