For the research and development of powder coatings for general use, Zhang Xiaofan basically doesn't pay much attention to it.

It is not because the profit margin of general-purpose coatings is low, but because after so many years of continuous discussion, each company has its own set of technical systems.

As a result, ordinary coatings are indeed very mature in all aspects, and it takes not only time to make innovations, but also great opportunities.

Zhang Xiaofan is now more concerned about some special-purpose powder coatings.

It can not be said that it is a special purpose, but a field where powder coating is difficult to penetrate.

This piece of car topcoat.

It is powder coating, which few companies in the world can relate to.

Do what others can't do, this is what Zhang Xiaofan wants to do.

The application of powder coatings instead of paint to automotive topcoats has been able to be carried out on a small scale for ten years.

The world's strongest R&D solid powder coating company, Feibao powder coating (the actual name is Tiger), was also really developed in about 18 years, which can be applied to the powder coating on the surface of automobiles.

This is a very big technological innovation, and it marks a big step forward in the real sense of powder coating instead of paint.

What Zhang Xiaofan wants to do is to develop a car topcoat that can replace paint when the raw materials of this brother are very backward compared with ten years later.

This is not only a technological progress, but also a leap in thinking, a fundamental understanding of powder coatings.

Automobile topcoat has always been a strategic place for all super-large paint and coating companies.

Many domestic enterprises, because of the lack of automotive paint and coating technology, so they cooperate with some foreign paint companies to establish a new brand, and specialize in automotive paint coatings.

From this point, we can deeply understand how profitable the car paint will be.

Whether it is from the perspective of his own reputation or from the perspective of making money, Zhang Xiaofan has a reason to vigorously develop this coating.

Leaving some people to dig deep into the potential of wheel coatings, and some people, Zhang Xiaofan gave the task of developing automotive topcoats.

However, what really needs to be developed for this car topcoat is still that layer of colored paint.

The layer of transparent paint on the surface of the car topcoat can be completely replaced by the transparent paint of the wheel hub.

In fact, car topcoats also need three layers of coating.

The first and third layers can be completely replaced by the first and third coats of wheel paint.

The first layer of primer is applied to the car topcoat.

The main role is not to fill in the defects of the substrate, but to increase the adhesion between the coloring layers of the substrate.

As for the coloring layers.

There will be a lot of varieties, our common pearlescent blue glitter, pearlescent brown glitter, pearlescent silver glitter, pearlescent red glitter.

In fact, it corresponds to the color of steam, blue, brown, silver and red.

If you don't look closely at these colors, you won't be able to see the glittering pearlescent pigments inside.

When you look closer, you'll notice, especially when the sun is shining, when the pearlescent colors are colorful.

In fact, if you look far under the sun, you can still feel the charm of pearlescent pigments.

However, this time the time was not urgent at all, so Zhang Xiaofan did not have the idea of leading the team in person.

With the research experience of wheel coatings, he believes that the technicians below should have a basic understanding of automotive surfaces.

The biggest difficulty in the coloring of automobile topcoat is how to knead the paint particles and pearlescent pigments together.

Because the pearlescent pigment content used in car topcoats will be very large.

Moreover, the dry mixing method is still used for paint particles and pearlescent pigments worldwide.

As a result, paint particles and pearlescent pigments are separate components that are mixed together.

When spraying, it is easy to cause one-sided color, and the surrounding color is not the same.

This is because the coating particles and pearlescent pigments are not the same when spraying.

In some places, the petition rate of pearlescent pigments is more, and in some places, the powder rate of pearlescent pigments is less, which will make the color different in these two places.

At present, this situation is very common in the paint market, so the application range of pearlescent coatings is still very narrow.

Occasionally we can see it on the guardrail, but not much else.

After explaining the technical difficulties, Zhang Xiaofan asked the technicians below to study it by themselves.

After all, Zhang Xiaofan can't help much with this kind of thing now.

The performance of raw materials at present and those in the next few decades is not half a star.

The technology of pearlescent coatings in Zhang Xiaofan's memory is relatively high-end, and that is because of the support of high-end raw materials.

However, many high-end raw materials have not been developed, so we need to rely on the wisdom of these technicians to solve this problem.

After the development of more high-end raw materials in the future, they have a certain amount of technical accumulation, and at this time, they may not need Zhang Xiaofan to provide technical support, they can solve the problem of adhesion between pearlescent pigments and paint particles.

And now Zhang Xiaofan has time to wait.

He has to wait until the cooperation between Fangnan Wheel and BMW is more deep, so that he can have the opportunity to contact BMW or other automobile companies.

Recommend powder coating topcoat to them, and it is best for Zhang Xiaofan to design a very reasonable process.

Otherwise, why should others believe you, and why are they willing to change paint to powder coating.

Car topcoats are not like wheels.

It is acceptable for automobile companies to have defects on the wheels, after all, when people buy cars, they rarely notice the paint defects on the wheels.

But if there are coating defects in the car topcoat, such as not enough gloss, not reflecting the human figure, or not beautiful enough, or not full enough, these flaws can be seen by others at a glance.

Don't underestimate the flaws in front of the car, a very beautiful car model is one thing, and the car topcoat also accounts for a large proportion.

Imagine a BMW car, the paint on it is the kind of hand-painted that we are commonly used to, with no gloss at all, and the surface is uneven.

Would you still buy it?

At this time, you don't have to think about it, even if your model is good, they won't buy it.

On the one hand, buying a car is for the sake of mobility, and on the other hand, it is definitely for the sake of face.

If you have too many flaws in the car topcoat, it looks completely incompatible with high-end cars, even if you are a BMW in that brand, but others may think that your car is a fake BMW, or it is a second-hand BMW completely.

In this case, where do you let others have face? I can't find the latest chapter of the book I want to read?cough cough, it's not a problem, I recommend a public account, there is a young lady here to help you find the latest chapters, and accompany you to talk awkwardly!
