From large lacquer to wood wax oil-the road to ideal paint (part 2)

Ten: Piano baking varnish

Piano baking varnish is a coating method that maximizes the protective effect of the paint film, and the process is very complicated.
First, you need to apply putty on the wood board as the bottom layer of the spray paint; after leveling the putty, let it dry, polish and polish it smoothly; then repeatedly spray the primer 3-5 times, and polish with water sandpaper after each spray; finally, again Spray 1-3 times of bright topcoat, and then use high temperature baking to cure the paint layer.

Compared with ordinary high-gloss spray paint, piano baking paint has two essential differences.
First, piano lacquer has a very thick primer layer.
In fact, if the surface layer of real piano lacquer is cracked hard, it will crack like enamel, instead of peeling off like a normal lacquer layer; second, Piano paint is a baking process, not a spray painting process, and has undergone a high-temperature curing process.

Because of this difference, compared with ordinary spray paint, piano paint is much higher in brightness, compactness, and especially stability.
If mechanical damage does not occur, the surface of piano paint will still be as bright as many years.
New, and ordinary brightness spray paint has long been oxidized and penetrated.

Piano baking paint is a term that is often misused.
As the cost of real piano baking paint is very high, the so-called piano baking paint on the market is actually a "polyurethane paint (PU) spray paint" process.
This paint is very close to the top paint composition of piano paint (the spray paint used in piano paint is "unsaturated polyester paint (PE)"), but compared with the piano paint process, this process does not have a spray primer, and It is not a paint baking process and has not undergone a high-temperature curing process, and the stability of the polyurethane paint itself is not as good as that of the unsaturated polyester paint.
The actual cost is much lower than the real piano paint, most of the "piano paint" we have seen are of this kind.

Eleven: Wood wax oil

The main components of wood wax oil are linseed oil, thistle oil, sunflower oil, soybean oil and carnauba wax.
The principle of action is equivalent to the improvement of the traditional combination of tung oil + beeswax.
The oil component can penetrate into the wood to moisturize and maintain the wood, reflecting the natural texture and texture of the wood; the wax component is firmly combined with the wood fiber, preventing liquid water from penetrating into the wood, and increasing the hardness and hardness of the wood surface.
Smoothness.
The main composition of wood wax oil is vegetable oil, and the tinting uses iron oxide and other pigments to eliminate toxic and harmful volatiles such as benzene and formaldehyde from the raw materials.
Therefore, its environmental protection performance exceeds that of water-based paints, and whether it is manufactured or used From a different perspective, wood wax oil consumes less environmental resources and is more beneficial to ecology and health.

It is no longer a fully enclosed paint film to protect wood products.
It is a pioneering work in the coating industry for wood wax oil.
Wood treated with wood wax oil not only has a unique natural texture, but also provides a skin-like touch.
The usual paint will form a plastic-like film on the surface of the wood, making it easy to touch no matter what kind of wood.
It is a cold polymer material.

The wood products treated with wood wax oil are closer to people, and the construction operation is very simple.
Just wipe 1-2 times with a brush or a clean cotton cloth.
After drying, use a scouring pad to polish and finish.
There is no technical difficulty for anyone, and it is very suitable for DIY, which will make the maintenance and maintenance of furniture a healthy and happy thing.

Judging the paint effect will emphasize the hardness and abrasion resistance of the paint film, but the anti-wear principle of wood wax oil is different from it, which can be described as rigid and flexible.
Although the paint film of polyurethane paint is hard, it looks smooth and shiny, it is easy to leave scratches during use, and it is difficult to repair.
After ten years, you may not bear to see it.
At this time, the only way is to ask professionals to wear off the paint film and renew it.
Painted.
The wood wax oil penetrates into the surface of the wood, and the opposite is done, using the flexibility of the wood itself to resist abrasion, there will be no obvious scratches, it is very easy to repair, you can do it yourself, so there is no problem in using it for decades.
Different people have different opinions.

The main purpose of using wood wax oil is for health, environmental protection and natural texture, but its application is still limited.
The protection principle of wood wax oil determines that it is only suitable for solid wood.
For wood board, density board, plywood, etc.
, which are widely used in the market, wood wax oil cannot exert its effect.
Even for solid wood, wood wax oil has different effects on different types of wood.

It is especially important to note that wood wax oil cannot hide the ugliness, and even deepens the color difference of the wood itself.
This may be the main reason why most furniture brands are reluctant to use wood wax oil.
But in our opinion, this shortcoming is also its advantage.
Wood is a natural material.
Of course, what appears in front of people is not only a perfect texture, but also tree knots, tree tumors and even insects.
If we look at it with awe and make good use of it, it will not only beautify life, It will also help us map out the path to understanding life forms.

Concluding remarks:

The exploration of ideal paint has a tortuous and long road.
The lacquer that has been used for thousands of years has always been regarded as the representative of the ideal paint.
However, the development and progress of the chemical industry in the past 100 years and the diversification of social needs have led to the gradual disappearance of lacquer from people's vision.
While modern coating products are widely used, humans are paying more and more attention to environmental protection and health issues, which promotes the transition of solvent-based coatings to water-based systems.
In the 1980s, wood wax oil appeared in Europe and quickly became popular.
It satisfies people's inherent needs in pursuit of nature and truly returns to the tradition of early plant coatings.
