Description
Product description
Aliphatic polyisocyanate (low-viscosity HDI trimer).).
Use as the hardener component for flexible, lightfast polyurethane coating
systems.
systems.
Solubility / thinnability
HDT LV 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
solvents.
HDT LV should not be thinned to below a solids content of 40 %.
Prolonged storage of a solution with a lower binder content may result in
turbidity and sedimentation.

Storage
- Storage in original sealed Covestro container.
- Recommended storage temperature: 0 - 30 °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.

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
HDT LV is used primarily as the hardener component for lightfast
two-component 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 HDT LV are
air- and force-drying coatings for automotive OEM, automotive refinishing,
transportation, industrial finishing and plastics.
On account of its low viscosity, HDT LV is particularly suitable for
the formulation of high-solids coatings and can also be used as the hardener
for aqueous two-component polyurethane coatings.
