Solubility Properties 
     

CORONATE 2384 is used as a curing agent for non-yellowing polyurethane coatings. Compared with curing agents of biuret and urethane adducts, it has unique and excellent characteristics. Because of its excellent heat resistance and compatibility with polyols and solvents. CORONATE 2384 is widely used in industry. It is used in motorcycle and automobile parts, automobile repair, woodworking, etc.

CORONATE 2384 is soluble in most ester solvents, such as ethyl acetate and butyl acetate; it is also soluble in aromatic hydrocarbons, such as toluene, xylene and other solvents. However, alcohols such as methanol, ethanol, etc. are not suitable for dissolving isocyanates.

when diluted
CORONATE 2384 can be diluted to 20% solids. However, please carry out a compatibility test with the diluted solvent first to confirm that it will be used later. When CORONATE HX is diluted below 20% solid content, turbidity and precipitation will occur. Please use a solvent with a moisture content of 0.1% or less.

compatibility
CORONATE 2384 has excellent compatibility with other CORONATE, NIPPON series products, polyester, acrylic resin, alkyd resin, fluoride. However, please conduct a compatibility test before mixing.

 

 application
      CORONATE 2384与丙烯酸系多元醇组合成的双组分型涂料具有优良的耐候性和抗磨损性,被用于汽车修补用涂料、工业用涂料等。
       CORONATE 2384与醇酸系多元醇组合成的双组分型涂料被应用于工业用、木工用涂料等。
       CORONATE 2384加入含有硝基纤维素系、醇酸系树脂或聚乙烯树脂的涂料时,能明显的提高涂料的物理性能,如抗溶剂性。但是,使用时必需对每种混合做非常仔细的兼容性实验。

  Precautions for use
· Storage conditions
Since CORONATE 2384 is an active isocyanate compound, it is very easy to react with OH groups. Storage must pay attention to keep away from moisture and store in airtight containers. For long-term storage, please keep it in a temperature environment of 15~25℃.
· When using and repacking
Isocyanate is a very active substance. When reacting with water, not only insoluble substances, such as urea groups, but also CO2 gas will be produced. When isocyanates are stored in a sealed container in which water is mixed, the internal pressure of the container increases due to the generation of gas, and the container may rupture. There is a problem of deterioration due to the action of moisture in the air when a small amount is taken several times from a container. Therefore, before opening and then sealing, it must be fully replaced with dry air, and great care must be taken to prevent moisture from mixing.
· When diluted
When CORONATE 2384 is diluted with solvent, not only should pay attention to the water content in the solvent, but also pay attention to prevent water from mixing in the dilution operation. The dilution work should be carried out in a dry room.

safety
①CORONATE 2384 must be careful when using it because it contains isocyanate.
②When using, please follow the requirements of the material safety data sheet (MSDS).
③ This product is flammable. Please use it in a fire-free place.
④ This product should avoid contact with eyes or skin. Please wear protective equipment such as safety glasses and gloves when using it.
⑤When spraying the paint containing this product, please wear protective equipment such as protective glasses and gas masks in order to prevent steam and fog from entering the eyes or nose.
⑥ The free isocyanate content of this product is below 1%. Long-term storage will not increase.
