Do not leave any filler on the surface of the material in the automatic spraying line. Otherwise, the adhesion will be poor.

OVERALL BODY STAIN

Also known as background coloring or material coloring, the background color gradually approaches the color of the sample and is usually painted.

Alcohol colorant (ALCOHOL STAIN)

Dissolve the acid dye in an alcohol solvent. Because alcohol has high compatibility with wood, it has good permeability, fast drying, and excellent coloring effect on hardwood. It is usually used for background coloring (full spray), filling dyeing, coloring stains and toners. This coloring agent is usually used instead of lint coloring agent.

No hair dye (N.G.R STAIN)

It is a combination of acid dyes and metal salts, and is soluble in hair alcohol-based diluents. (Mixed solvents such as ethanol, methanol, toluene, etc.) Generally, the full spray method is used, and white water can be used to prevent the drying speed.

Advantages: no swelling, no hair, no spitting, high air permeability, fast drying, bright color, good light resistance.

Disadvantages: difficult to brush, high price, and alcohol in the solvent. If it is not sufficiently dried, a reactive coating such as PU is applied to the reaction sheet, and the coating film is prone to wrinkles.

Understand and master the terminology used by automatic coating equipment, it is easier to improve coating efficiency and coating effect in daily operations. Experience slowly accumulates. As a numerically controlled automatic spraying equipment, its operating essentials have gradually accumulated.
