N3300 ISO 14001 Aliphatic Isocyanate Hardener For Lightfast

N3300 Aliphatic polyisocyanate HDI trimer

^{1. Characterization}

Aliphatic polyisocyanate (HDI trimer).

As the hardener component for lightfast polyurethane coating systems.

^{2.Properties / Applications}

^{Desmodur® N 3300 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 3300 are air- and force-drying coatings for automotive OEM, automotive refinishing, transportation, industrial finishing, and plastics.}

^{3. 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.}

^{4. Specification}

^{5. 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.}

^{6.Properties & Applications}

^{Desmodur® N 3300 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 3300 are air- and force-drying coatings for automotive OEM, automotive refinishing, transportation, industrial finishing, and plastics.}

^{7. Storage & 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 six 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 six 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 six months. Co vestro shall not be responsible or liable in any way for the development failing to meet specifications or the set values after the lapse of six months. However, before using said product, Covestro recommends testing such a product to see if it still meets the specifications or the set values.}

Learn polyaspartic knowledge: Polyaspartic FAQ

Shenzhen Feiyang Protech Corp., Ltd. specializes in researching and producing polyaspartic polyurea resin and other new chemical products. We are recognized as a "National Special New Key Little Giant" and a "State-level High-tech Enterprise", with more than 50 polyaspartic polyurea invention patents. We also participated in the preparation of 13 industry standards for polyaspartic polyurea materials as a leading company in this field, ranking No.1 in the Chinese market.

In the coating industry, polyaspartic polyurea is used in construction machinery, automobile, containers, fan blades, marine heavy corrosion protection, and high-end industrial and commercial floor coatings. In the adhesive field, it is mainly used in sealants, stone adhesives, electronic adhesives, film circuit packaging adhesives, and other high-end applications. In the waterproofing materials sector, it is primarily used in hydroelectric dams, water parks, building waterproofing repair materials, and other areas. In the structural materials field, it is applied to curling tracks, artificial ice skating rinks, and other structural materials.

Polyaspartic polyurea is considered a high-end new material in the strategy of manufacturing power. We have broken the foreign technology monopoly and filled the domestic market gap. Due to its comprehensive characteristics of "Environmental protection, Energy saving, and Long durability", polyaspartic polyurea can contribute to the realization of genuine carbon neutrality in the coatings, adhesives, and materials industries.

Since 2012, Feiyang polyaspartic ester resin has been supplied overseas. It has been widely used to replace Bayer's current polyaspartic system in many coating companies and has been applied in anti-corrosion and waterproofing by international coating companies.
