3. Solubility / thinnability
Desmodur® N 3300 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.
Desmodur® N 3300 should not be thinned below a solids content of 40 %. Prolonged solution storage with a lower binder content may result in turbidity and sedimentation.
4. Compatibility
Generally speaking, Desmodur® N 3300 can be mixed with the following products: aliphatic polyisocyanates such as Desmodur® N 100, N 75, N 3200, N 3400, N 3600 and Desmodur® Z 4470; aromatic polyisocyanates such as Desmodur® L, HL, and IL; polyester polyols such as Desmophen® 670;
polyacrylates such as the Desmophen® A products. However, the compatibility of the combinations used should constantly be tested.
Desmodur® N 3300 is incompatible with branched polyester polyols such as Desmophen® 651 or polyether polyols such as Desmophen® 1380 BT.
5.Properties / Applications
Desmodur® N 3300 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.
The main applications for systems based on Desmodur® N 3300 are air- and force-drying coatings for automotive OEM, automotive refinishing, transportation, industrial finishing, and plastics.
6. 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.
