The clarity is one of finishing character that is very important in the wood finishing. The clarity is how clear the finishing film is. The finishing with low clarity will feature a finishing with a dull appearance, while the high clarity finish will show clear finishing that can display the beauty and richness of the wood color. The clarity of the finishing layer is one indicator of the quality of the finishing layer. A wood with nice grain pattern and good color finishing will be looked awful if the finish has low clarity. In the other hand the nice grain and rich color of the wood will be maximally displayed with a high clarity film layer.
Clarity is sometimes associated with the gloss of the finishing. But actually they are two different things. Gloss is a measure to the shiny of the surface, while the clarity is how clear the finishing is. It is true when the higher finish will make the finish is more clear and bright. The high gloss will do little to increase the clarity, but it is not much. The high quality finish with high clarity has to be built with a correct finishing system
Here are the things that will affect the clarity of the finish layer.
- The finishing process.
- The type clear coating is used.
The clarity of the clear coating depends on the mixed resin therein. The NC clear coating is a finishing material that will produce the highest clarity. The NC finish will be able to produce a very clear and natural looked finish and show the beauty of patterns of the wood grain and color. The other type of clear coating will produce a layer of finish with different clarity. The finishing materials made from 2 components such as AC and PU can not produce a clear film layer as clear as NC. The chemical reactions during the drying process would affect the clarity of the coating film formed. The water based clear coating will also generated a little haze in its coating film. The acrylic and butyrate clear coating will also produce a little white haze on its finishing film, since that it more proper to the white finish. Each type of finishing materials each have advantages and disadvantages, then we need to choose the best suit materials according to the finish expectation.
- The existence of oil solvent in the finishing layer.
- The wet wood.
