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
