Desmodur N 3600 wannate HT-600 TPA-100 HDMI Hardener
A hardener is a component of certain mixtures. ... A hardener can be either a reactant or a catalyst in the chemical reaction during the mixing process. In other combinations, a hardener is used as a curing component. A hardener may also be known as an accelerator.
1. Characterization
Aliphatic polyisocyanate (HDI trimer).
As the hardener component for lightfast polyurethane coating systems.

3. Solubility
Desmodur® N 3600 can be thinned with esters, ketones, and aromatic hydrocarbons such as ethyl acetate, butyl acetate, PMA, 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 hydroxyl or amino groups). Aliphatic hydrocarbons are unsuitable as solvents.
4. Thinnability
Desmodur® N 3600 should not be thinned to below a solids content of 40 %. Prolonged solution storage with a lower binder content may result in turbidity and sedimentation.
5. Compatibility
Generally speaking, Desmodur® N 3600 can be mixed with the following products: Aliphatic polyisocyanates like Desmodur® N 100, N 75, N 3200, ultra N 3300, N 3400 and Desmodur® Z 4470; aromatic polyisocyanates like Desmodur® L/ultra L, HL and IL/ultra IL; polyester polyols such as Desmophen® 670 and polyacrylates. However, the compatibility of the combinations used should be tested.
Desmodur® N 3600 is incompatible with branched polyester polyols such as Desmophen® 651 or polyether polyols such as Desmophen® 1380 BT.
6. Properties
Desmodur® N 3600 is primarily the hardener component for lightfast two-component polyurethane coatings with high chemical and weather resistance, good gloss retention, and outstanding mechanical properties. Preferred co-reactants are polyacrylate or polyester polyols.
7. Applications
The main applications for systems based on Desmodur® N 3600 are air- and force-drying coatings for automotive OEM, automotive refinishing, transportation, industrial finishing, and plastics.
Because of its low viscosity, Desmodur® N 3600 is particularly suitable for formulating high-solids coatings. It can also be used as the hardener for aqueous two-component polyurethane coatings.
8. Storage
- Storage in original sealed Covestro container.
- Recommended storage temperature: 10 - 30 °C.
- Protect from moisture, heat, and foreign material.
General information: The product is sensitive to moisture and should therefore be stored in tightly sealed containers. Storage at elevated temperatures will lead to an increase in viscosity and a reduction of the NCO content.
