Why are fluorocarbon coatings popular in exterior wall painting?

"The advantages of fluorocarbon coatings for exterior walls"

01 

Scope of application of fluorocarbon coatings for exterior walls

As a recognized weather-resistant product, fluorocarbon coatings are currently used more and more on exterior walls, including:

1.

2.

At present, the refurbishment period of ordinary building exterior walls is shorter than ten years.

Now it seems that the exterior wall fluorocarbon paint is not only suitable for all kinds of public buildings: such as: office buildings, schools, hospitals, etc.

Therefore, we believe that the fields where coatings can be used for on-site construction of exterior walls are actually suitable occasions for fluorocarbon coatings

Scope of application of fluorocarbon coatings for exterior walls

Contrast tiles and tiles

Compared with the curtain wall of public buildings, it is used in many civil building surface brick products and has always been the darling of the decoration field

First: the ceramic tiles have safety problems.
Before their service life, due to various factors such as construction technology, meteorology, etc.
, the tiles will fall off, which constitutes an incident of injury
.
In reality, the durability of rigid decorative materials such as tiles, mosaics, and marble does not mean durability.
The deterioration of the atmospheric environment and the characteristics of the body material are destined to have a much shorter service life than expected
.
In the past, people thought that exterior wall coatings had good effects, but exterior wall coatings were very easy to age and fade.
They had to be repainted within a few years.
The old cost was naturally high
.
In fact, in the 1980s and 1990s, there was no serious concept of exterior wall coatings beforehand, and the standards were not unified.
The quality of paint production companies was uneven, and some low-quality and low-grade paints did fade within 1 to 2 years after painting.
coating or fall off
.
At present, due to the rapid development of coating technology, coatings are fully surpassing ceramic tiles in terms of color and decorative effects, and their color retention can often reach more than 8-10 years, and fluorocarbon paints can be used for more than 20 years
.

Second: The tiles fall off and the exterior walls are cracked
.
Water leakage is a major criticism of tiles
.
Today's coatings are not limited to decorative effects, but their expansibility has been effectively developed.
The full range of coatings has elastic waterproof performance and adhesion
.
Effectively solve a series of problems such as peeling, cracking, and water leakage of the outer wall over time
.

Third: The cost of ceramic tiles and the cost of paint are not comparable at all, and the economics of paint conform to the concept of environmental protection
.
It is practical and oriented towards fashion and simplicity
.
Ceramic tiles are expensive and have many shortcomings
.
The overall promotion of exterior wall coatings is the general trend, and we can see the evolution of the use of exterior wall decoration materials in China
.
Even the actual material cost of fluorocarbon paint is not high
.
Due to the long life, the "full life cycle cost" of fluorocarbon paint is lower
.

Fourth: Although the country has no compulsory regulations for the time being, relevant regulations have been issued in various places: the use of exterior wall tiles is prohibited on the exterior walls of buildings where there are pedestrians or crowds of people (except for the ground floor or outer wall facing materials of the podium)
.

Contrast curtain wall

As a high-end decoration, curtain walls are generally used in public buildings, and the price is high.
The cost of glass curtain walls is generally more than 1,000 yuan/m2, and the cost of aluminum and stone curtain walls is also hundreds of yuan.
Although many high-end real estates are also used now, the price is relatively high.
Compared with the large number of other civil buildings, the utilization rate is not high
.

In fact, no matter how regular the curtain wall is cleaned, the maintenance cost is not low.
Aluminum curtain walls and stone curtain walls also have great pollution problems.
If they are not solved well, their aesthetics will be greatly reduced
.

Simply put, the safety of the tile system and the price of the curtain wall system are the main reasons why these systems are far less widely used than coating systems
.

The advantages of fluorocarbon paint compared to other coatings on exterior walls

Ordinary paint is currently the mainstream of exterior wall applications.
At present, latex paint, real stone paint, and colorful paint belong to the most used varieties
.

Latex paint is actually a general term for a large category of products.
The products vary greatly in price and quality.
From the point of view of definition, water-based exterior wall fluorocarbon paint can also be regarded as a latex paint, but its overall performance belongs to this type of paint.
The best variety
.
Relatively speaking, the general performance of high-end products with certain well-known brands on the market is also guaranteed.
Outdoor use is still guaranteed for 5 years, but in view of the low overall threshold of latex paint
.
The standard lower limit of weathering life is 250 hours, and the lower limit of water-based fluorocarbon paint is 3000h, so the outdoor service life can be imagined
.

Real stone paint is popular on exterior walls due to the texture of its surface and the fidelity of imitation stone.
In fact, the main problems faced by real stone paint are:

1.
It is easy to get dirty.
The texture of the surface of real stone paint is rough, so it is easy to accumulate dust.
Even if stain-resistant varnish is used, it is generally difficult to completely solve it;

2.
Real stone paint is a large category.
If natural stone is used as the color, there may be radiation risks.
If color-dyed sand or pigmented quartz sand system is used, the weather resistance is also poor, and the color will fade in a short time.

.

As the new darling of the construction market in the past two years, colorful lacquer is widely used in large-scale high-rise residential areas because of its more realistic effect of imitation stone
.
The industry standard HG 4343 requires the weather resistance of the coating to reach 1000h, which is considered to be greatly improved compared to latex paint, but the requirement is only 1/4 of that of fluorocarbon paint.
In fact, the effect of outdoor use is not ideal.
Relatively speaking, colorful paint The color of the exterior wall is more vivid than that of the general latex paint, so the weather resistance problem is actually more prominent
.
In addition, the current real-variety sand-in-water products of colorful lacquer have the problem of poor stain resistance of real stone lacquer
.

The overwhelming advantages of fluorocarbon paint in weather resistance and the good stain resistance of the fluorocarbon surface itself make fluorocarbon paint have a much higher level than other commonly used coatings on the market in terms of outdoor durability and easy maintenance
.

I think in view of the advantages of these two important indicators, fluorocarbon paint has extremely suitable application value in exterior walls
.
