Detailed Product Description


The nitrocellulose products can be classified into H-type and L-type based on their nitrogen content


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.
