Customer Reviews
FEIYANG did offer their professional services and products to us. That is why we have had a long-term and stable business with them for several years. Nowadays, we are more like partners instead of just one of their distributors. Also, I hope we can expand markets in the future together.

—— USA Distributor

Feiyang is a reliable supplier, not only their product quality but also their professional technical support and service. We have done business together for six years already, which contributed to the growth of our business from nothing to several containers annually. We are so happy and lucky to have Feiyang as our partner.

—— European Distributor

We are very happy to be one of Feiyang's distributors in Australia. They are pretty nice supplier. They always do their best to meet our requirements. Our customers also trust Feiyang's high-quality product and out-standing service. Looking forward to developing more business together.

N3600 Aliphatic polyisocyanate HDI trimer​
 
1. Characterization
Aliphatic polyisocyanate (HDI trimer).
As the hardener component for lightfast polyurethane coating systems.
 
2.Properties & Applications
Desmodur® N 3600 is used primarily as the hardener component for lightfast two-component polyurethane coatings with high resistance to chemicals and weathering, excellent gloss retention, and outstanding mechanical properties. Preferred co-reactants are polyacrylate or polyester polyols.
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.
 
3. Solubility / thinnability
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.
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 such as Desmodur® N 100, N 75, N 3200, ultra N 3300, N 3400 and Desmodur® Z 4470; aromatic polyisocyanates such as 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 constantly be tested.
Desmodur® N 3600 is incompatible with branched polyester polyols such as Desmophen® 651 or polyether polyols such as Desmophen® 1380 BT.
 
6. Storage and storage time
- 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.
 
Covestro represents that, for nine months following the day of shipment as stated in the respective transport documents, the product will meet the specifications or values outlined in section "specifications or characteristic data" above, whatever is applicable, provided that the product is stored in full compliance with the storage conditions outlined in and referenced under section "storage" above and is otherwise handled appropriately.
The lapse of nine months does not necessarily mean that the product no longer meets specifications or the set values. Covestro does not make any representation regarding the product after the lapse of the nine months, and Covestro shall not be responsible or liable in any way for the development failing to meet specifications or the set values after the reverse of the nine months. However, before using said product, Covestro recommends totestinguch a product to see if it still meets the specifications or the specified values.
