Industrialnitrocellulose

Industrial Nitrocellulose (NC)is the reactant of nature cellulose and nitrate acid. It is a kind of white flocculus or flake fib

NC for coatings

        1. Classification

        1.1 according to specification the industrial nitrocellulose should       contain at least 25% of wetting agents that water or alcohols are usually       used as. SNC can provide nitrocellulose products containing different       kinds of wetting agents such as water, ethanol, isopropanol, n-butanol,       etc.SNC also provides nitrocellulose chips, a flaky product from plasticized       NC with (no less than) 18% of plasticizers, such as DBP, DOP, etc. after       replacing the water in NC.

         1.2 The nitrocellulose products can be classified into H-type and       L-type based on their nitrogen content and, in turn, subdivided into       different grades according to the viscosity in the standard NC Solution       (see Products Specifications).

         Features of H-type

         To form a tougher film.          Evaporate its solvents faster than L-type.          Be diluted easily with alcohols, aromatic and aliphatic solvents.          Possess more excellent mechanical performances.          Since it can be readily dissolved into esters solvents, H-type product       is also called ester-soluble nitrocellulose.

         Features of L-type

         Form a thermoplastic film. Dissolve into large amounts of alcohols       (such as methanol or ethanol) with small amount of esters.         Be diluted easily by aromatic solvents.          L-type product is also called alcohol-soluble nitrocellulose since it       can be readily dissolved into alcohols

         2. Designation

         Type + Viscosity + wetting agent

         For example: The nitrocellulose product with high nitrogen content, 1/2       second of viscosity and ethanol wetting agent is designated as H 1/2 EA.

         Type + Viscosity + wetting agent

         For example: The nitrocellulose product with high nitrogen content, 1/2       second of viscosity and ethanol wetting agent is designated as H 1/2 EA.

       3.Viscosity specification

 

         4. Each kind of nitrocellulose should conform to following viscosity       requirements

      

         Technical Specification to NC for coatings

 

          Note: 1, there is no necessary to do moisture test to NC damping with       water. If the customer has any special requirement for viscosity or other       items decision should be made by negotiation between the seller and buyer.

      5, the wetting agents included EA (ethyl alcohol), IPA (isopropanol),       n-butanol, water, etc.          The products should conform to the standard of Q/HE2—125-2000                    Classified brands according to viscosity
