Commercial nitrocellulose is generally damped with alcohol or water to prevent the danger of fire accident. These damping materials, however, act as obstacles for nitrocellulose to be applied in urethane resin based formulation due to their incompatibility. Nitrocellulose can give necessary hardness, drying speed, and excellent dispersibility to the soft urethane formulation and when it is successfully applied by removing alcohol and /or water, a wide range of application becomes possible, e.g. coating material for high-performance magnetic tape.

Magnetic tapes are made by applying a coating material containing magnetic iron powder to a polyester film substrate. Extremely fast drying speed and highly uniform dispersion of the powder are very essential for its process. Our alcohol free nitrocellulose chip HC/HM series can meet these requirements and is recognized as the best binder for high-performance magnetic tapes.

This property of alcohol free and extremely low in water content also allows SwanCel a various application to the urethane based industry and expands its demands constantly.
