Aniline, dye, organic pigmented stain in the wood finishing

Aniline, dye, organic pigment

Aniline stain or dye stain is one type of stain is widely used in the finishing process for wood furniture. Aniline or dye is one type of organic pigments that is most used in the wood finishing industry. This stain can be recognized by its strong, bright, and transparent appearance. In addition, this stain also will not settle if it is solved in the appropriate solvent. The particles of dye stain are very small sized make this material can be perfect dissolved in the solution.
The aniline stain are preferred because it can make a bright, transparent and strong coloration. You can view it in the properties of pigment stain. Now the finishing material manufacturer is currently providing this stain type in many colors. We as finishing people can easily choose the most suitable stain as needed. If we purchase this material in large quantities many finishing industry players are willing to mix the stain within the color we need.
But we need to know that the aniline has low resistance to the UV rays. This aniline stain is not recommended for staining to the outdoor finish.  The colors produced will quickly fade when used in the outdoor products. For the outdoor finish, the inorganic pigmented stain or special organic pigment are recommended.
Although this stain has been available in a variety of colors but sometimes the finishing people prefer to mix this stain himself. A dye with the primary colors can be diluted and mixed to form the desired stain color. (We can use the principle of triangle color theory to do the mixing color). The aniline pigment is available in 2 forms: the aniline powder and high-concentrate liquid aniline. The powder should be dissolved first in an alcohol liquid before being mixed to make the desired color. While the liquid form dye can be directly mixed to produce the desired color. The mixture can be diluted again with various solvents to be arranged so it can be applied in accordance with needs.

  
Water based stain
 
A dye mixture can be thinned with water to make water based stain, of course we need some additive material to add the solubility. Water based stain can be applied directly on the wood with very attractive staining results. The resulting color is a bright, transparent, and enhances the beauty of the grain pattern of the wood. The stain that consist small particles of pigment can penetrate in and wood and color to the pores and grain. This stain can be applied by spray brushed or wiped with good results.

Non-grain raising stain (NGR stain)

The problem with this stain is the water in the mixture will raise the wood fibers and produce a rough surface. The uses of this stain will require an extra sanding and clear coating application to produce a smooth surface. To reduce the raising wood fibers, the finishing material industry make a stain that is known as a non-grain raising stain. Stain is made from aniline pigment diluted in alcohol and some toluene. This stain can reduce wood fibers rises when it applied. It will produce a smooth surface finish quickly. But since it dries quickly, this stain cannot be applied by wiping or brushing.  The spray application by spray is the recommended way of application for this stain.

 
Pad stain, shading stain
 
Pad stain is a dye stain is primarily used to color on the clear coating. This stain is widely used for adding color to produce balanced and equal color to a furniture product in the final finishing. The additions color by this stain (shading) is usually done on a sealer or top coat before the final top coat. The bright and less cover character of this aniline stain will reduce the risk of  "too close stain"  which will and reduce the beauty of wood grain character appearance.
Pad stain is can be applied by padding. The padding technique can be used to adding the color or to produce special effects finishing required.
