Lacquer thinner is the thinner that is special designed to thin the lacquer. Lacquer is finishing a material that is dry and forming hard film layer by evaporation his thinner. According to this definition the lacquer are: nitrocellulose coating, acrylic clear coat, butyrate clear coat, vinyl material and the other 1 component coating materials. While the other coating that is dry film by chemical reactions such as: Polyurethane, Acid curing, Precatalyzed and Polyester are not included in the lacquer category.
The main function of the lacquer thinner is to reduce the viscosity of the lacquer so that it can be applied easier. The original lacquer is a viscous material that can not be applied by spray gun. Spray gun as the main equipment for lacquer application only works well to the materials with low viscosity (about 14 second with Nk # 2 viscosity cup). The application by brush also can not give good layer when the viscosity of the material is too thick.
Instead of reducing the viscosity the lacquer thinner also work to give some specific characters at the mixture. The lacquer thinner is also used to make better flow and adjust the drying time of the lacquer.
Lacquer thinner does not leave at the film resulted; it will evaporate in the drying process. Lacquer thinner is just a “vehicle” that deliver the lacquer to his destination without form the film layer. Although it just a vehicle, but the lacquer thinner play important role in the finishing process. Many finishing problems occur because are caused by inappropriate thinner, on the other hand, there are many adjustment can be made in the lacquer application by select and modify the lacquer thinner.
How lacquer thinner is made.
Lacquer thinner is made by a mixture of several solvents. The composition of the lacquer thinner could be varied from one supplier to another. The composition of lacquer thinner is highly dependent to the type and ingredient of lacquer that will reduced. Since the composition of the lacquer is different from one manufacturer the other, then the composition of the lacquer thinner is also varied form one manufacturer to the others.
Basically the lacquer thinner is made of three kind of material, the solvent, latent solvent and diluent.
Tips on using lacquer thinner
- Latent solvent
- Additive materials
Tips on using lacquer thinner
- Use lacquer thinner according to the lacquer materials used.
- Do some test and experiment before use the thinner in the large scale.
When we decide to change the lacquer thinner we must do some test first before use it in the large volume application. Mix some material with the thinner and see the results. View the physical properties and looked of mixtures such as: the clarity, solubility, and viscosity of the mixture. Then we still need to test it by applied the mixture on some piece of wood panel. See the result such as the drying time, the flow, the appearance, etc. After we are confident that the mix is working well, then we can start to use the material on a larger scale.
