Where do you have to study and use water-grained powder coating in your life?

Water-rippled powder coating, also known as water ripples, is a kind of powder coating with a highly decorative powder coating
after the powder coating is applied to a film, and the coating is similar to the water ripple pattern.

China's land and wealth of cultural origins are rich, and the domestic names of water-grain powder coatings are different, among which powder coatings with the title of water pattern, cotton paint, wrinkles, leather grain, cloth pattern, mesh pattern, tortoise pattern are the most common
.

Because water-patterned powder coatings have a strong decorative effect, coupled with water-patterned powder coatings on product design technology, manufacturing equipment and coating technology are high requirements, plus the cost and price of such powder coatings are higher than conventional powder coatings, can be used in different environments inside and outside, so water-patterned powder coatings are often promoted and applied online coatingol.

as a high-grade and highly decorative powder coating in the market.

Preparation of powder coating appearance and effect of water-based powder coating coating

Water-patterned powder coating has a water-like ripple-like effect, see Figure 1~Figure 4 comparison chart
.
It can be seen that water-grained powder coatings can form an effect with large ripples to smaller cotton lines, with a very rich textured appearance
.

Because water-grained powder powder coating has rich colors, from black to white, from red to green, from blue to yellow, from dark colors to bright colors can be achieved, see Figure 5 ~ Figure 8
.

Water-patterned powder coatings have a shiny, soft luster, or a lifeless dry sheen
.
The perfect combination of texture effects, color and gloss can achieve endless variations, almost meeting the needs
of color and texture of the painted object.
Obviously, from bright to antique colors, water-patterned powder coatings can give an almost perfect visual feel
.

The appearance of water-grained powder coating can give people the desired "touch feeling", which can be very smooth and delicate, or very rough, which can meet the needs
of product designers for touch.
After the water-pattern powder coating is painted, a coating film is formed on its surface, which brings people the enjoyment of beauty and greatly prolongs the service life
of the product.

With the continuous improvement of people's material living standards, the demand for spiritual aspects is getting higher and higher, and the gorgeous appearance and bright and dazzling colors of the product water pattern coating can make people feel pleasant
.

Water-patterned powder coating design and manufacturing technology

Water-based powder coating products, like other texture powder coatings, are divided into two base material types for indoor applications only and general for indoor and outdoor environments
.

Water-patterned powder coating only for indoor applications, mainly epoxy resin-dicyandiamide as the main base, sometimes using a small amount of medium and high acid value polyester resin to adjust the appearance effect of the product coating, production and coating stability, the baking process of the binder in the process of acetylacetonate aluminum (known as cotton agent or water pattern agent) catalyzed to form a water-pattern effect of the coating appearance
.

When designing such powder coatings, special attention should be paid to the use of inferior epoxy resins mixed with intermediates in China, so as not to cause poor product batch stability and unstable
coating performance.

When designing such powder coatings, a small amount of 4/6 type polyester resin with an acid value of about 50mgKOH/g is often used to adjust the appearance and intrinsic properties of the coating, and the appropriate use is often unexpected
.

In particular, epoxy resin type water-patterned powder coatings use a catalyst of aluminum acetylacetonate, which often causes nosebleeds, pink eye and other occupational diseases that endanger health in production operators during use, and will cause blindness of production workers in severe cases, which has been found in the domestic powder coating manufacturing industry and coating application industry
.

Therefore, with the increasing attention to occupational health today, the hazards of such water-patterned powder coatings have attracted more and more attention, and such epoxy-type water-patterned powder coatings with aluminum acetylacetonate as catalyst will slowly fade out of the application market
.

Water-based powder coatings based on epoxy resin are limited to indoor applications
because they cannot meet the requirements of outdoor application environments for product weather durability.

Therefore, the water-based powder coating that can be used in the outdoor environment with polyester-amino resin as the main base material has not withdrawn from the Chinese market under the situation of high cost and high price, and has always played a role in the market as the hegemon of high-grade powder
coatings.

With the successful development, promotion and application of domestic hydroxyl-terminated special polyester and tetramethoxymethylglyceron products, Creamyth WL32-18A, Creamyth WL64-96A, Creamyth WL52-98A three Creamyth®®®®WL series products have been launched successively with the in-depth study of such powder coatings, and with the continuous decline of raw material prices, It has opened the door
for the widespread promotion and application of polyester-amino resin waterborne powder coatings in China.

Due to the water-based powder coating prepared by Creamyth®WL series amine blocking sulfonic acid catalyst, it has the characteristics of environmental friendliness and health safety for production and operation workers, which has attracted more and more attention
from the industry.

Water-based powder coatings based on polyester-amino resin can form a variety of texture effects, have a full range of colors, have a wide range of gloss adjustment, and have excellent outdoor weather durability, so that such water-based powder coatings can be used in a wide range of indoor and outdoor application environments and occasions
.

Whether it is a water-patterned powder coating based on epoxy-dicyandiamide, or a water-patterned water-patterned powder coating based on polyester-amino resin, it puts forward high design requirements for product designers, and good product design thinking and experience can bring higher and better production and application stability
for product manufacturing and coating applications.

In addition, although all powder coating manufacturers can use their own original equipment to prepare water-based powder coatings, the same formula and the same raw materials will always get a coating with a significantly different water-pattern effect in different powder manufacturers
.

Therefore, paying attention to the research of powder coating preparation process and equipment will be more conducive to the preparation and application
of water-patterned powder coating products.

Water-based powder coating applications

Coating powder coatings is the final step
in the production of all products.
After the product is painted, a coating film is formed on its surface, which brings people the enjoyment of beauty and greatly prolongs the service life
of the product.
In order to make the performance of the coating film meet the corresponding use requirements, the appearance and intrinsic quality
of the coating film should be ensured.

Appearance quality includes color, flatness, gloss and impurity content; The intrinsic quality includes physical and chemical properties, mechanical properties and special properties
.

In the actual coating work, there are quite a few products that require coating, first of all, to ensure that the product has a good decorative effect, and secondly, to require the coating film to have a certain protective function
.

Because with the continuous improvement of people's material living standards, the demand for spiritual aspects is getting higher and higher, gorgeous appearance, bright and dazzling colors, can make people have a pleasant feeling
.

Polyester-amino water-pattern powder coating has excellent diversity of touch due to its rich variety of texture appearance, rich and diverse colors, a wide range of gloss adjustment, excellent coating mechanical and chemical properties, excellent outdoor weather durability, excellent coating performance and suitable for cold furnace curing, elegant and solemn
appearance.
Excellent
scratch resistance, weather resistance and wear resistance.

In line with SGS green environmental protection, no damage
to the human body.
Excellent workability and good

See Figure 15~16
.

06Building aluminum profiles, guardrails and horticultural facilities

Outdoor building hardware, aluminum, guardrails and horticultural facilities and other powder coatings have high requirements for outdoor weather resistance, mechanical mechanics and other comprehensive performance requirements, and the early water-based powder coatings can not meet their application requirements
.

However, with the development of powder coating raw material technology and the richness of types, with the development of polyester-amino weather-resistant powder coating design, manufacturing and application technology, the weather resistance, chemical resistance, mechanical and mechanical properties of water-patterned powder coatings have all gained a leap.

Therefore, polyester-amino weather-resistant waterborne powder coatings are gradually used in the building materials industry to meet people's aesthetic needs, and it is believed that water-based powder coatings will be widely used in the construction field
in the near future.
See Figure 17~18
.

07 Automotive industry

The application of powder coatings in auto parts began in the mid-70s of the 20th century, such as for suspension parts, engine bodies, oil filters, wipers, air purifiers and brake pipes and other components, and its preferred variety is epoxy powder coatings;

Powder coatings for external metal components such as shock absorbers, door and window components, wipers, luggage racks, automobile chassis, steel rings, bumpers, etc.
, polyester or acrylic are the preferred systems
.

Almost all external metal components can be powder coated, roof fences, doors and windows components are typical exterior decoration parts, the color is usually black or dark gray, requiring UV aging resistance and excellent
aesthetics.

Waterborne powder coatings are suitable for automotive parts and decorative parts, and can provide excellent decorative, anti-corrosion, weather resistance and stone chip resistance
.

Development of water-based powder coatings

Epoxy resin water-patterned powder coating for indoor metal products, because it is prepared by using aluminum acetylacetonate as a catalyst that is still irreplaceable and indispensable raw materials, in the mass production and coating application of such products, it is very easy to cause serious occupational diseases such as nosebleeds, tears, pink eye and other serious occupational diseases for production and operation employees, which seriously endangers the health of production and operation employees, and more terrible, it will cause some employees to be blind
.

After long-term in-depth research, Shang Xinxue, which has very mature design and development experience in China, has developed Creamyth®32-18A, a catalyst to replace imported amide-blocked sulfonic acid catalyst 32-18A, since 2010, and has been widely promoted and applied
at home and abroad.

Subsequently, in 2012 and 2013, two amene-blocked sulfonic acid catalyst products were launched successively, Creamyth 52-98A and Creamyth 64-96A, which expanded the limitations and application scope of Creamyth®®®32-18A products, which are the first in China and some products are the first in the world
