Polyurethane for preventing refrigerant leakage.

Polyurethane for preventing refrigerant leakage.

We recommend Polyurethanes for leak prevention in heat exchangers.

About half of the heat exchangers we are currently painting are for the purpose of preventing refrigerant leakage. In an environment containing acids, sulfur, and ammonia, corrosion occurs in the copper pipes of the vent section, leading to pinholes and resulting in the leakage of refrigerants and Freon. Polyurea prevents the occurrence of corrosion, thereby preventing Freon leakage. Although measures against Freon leakage are becoming stricter, we recommend Polyurea for preventing leakage in heat exchangers, which are one of the components that are difficult to replace. Please note that copper pipes that have already begun to corrode may experience leakage during the painting process, so as a rule, we do not paint anything other than new parts. *For more details, please refer to the PDF materials or feel free to contact us.

Polyual for reliable salt damage protection for outdoor units.

Polyual for reliable salt damage protection for outdoor units.

Suppressing the year-on-year changes in electricity usage! Measures can also be taken for cases and copper pipes with special paint.

In Okinawa, a region affected by severe salt damage, neither salt-resistant nor heavy salt-resistant specifications are used. Instead, a special coating known as "Okinawa coating" is used to protect the aluminum fins. However, the thin salt-resistant and heavy salt-resistant specifications, which are only a few microns thick, deteriorate and peel off almost completely within a year under direct sunlight. The aluminum fin deterioration prevention paint "Polyual" is 20 microns thick, similar to the Okinawa coating, making it less susceptible to UV damage and providing long-lasting durability. 【Brigold's Solution】 ■ A world-leading technology used for 30 years in 50 countries ■ A dedicated protective agent for aluminum fins that reliably protects the fins ■ High thermal conductivity that maintains and restores the performance of aluminum fins ■ Outdoor units in use can also be painted ■ Repairs through touch-ups provide semi-permanent protection for the fins *For more details, please refer to the PDF document or feel free to contact us.

Polyurethane for salt damage prevention in microchannel heat exchangers.

Polyurethane for salt damage prevention in microchannel heat exchangers.

It protects the heat exchanger of the air conditioning and refrigeration refrigerator permanently!

If you continue to use fins that have deteriorated due to salt damage, it may lead to unexpected increases in electricity consumption and sudden high-pressure cuts, resulting in operational losses, which can significantly impact management. Microchannel heat exchangers, as their name suggests, have very fine piping through which the refrigerant passes. Therefore, if a refrigerant leak occurs, the small amount of refrigerant leaks slowly, making it difficult to detect until there is an increase in electricity consumption and further operational losses. In response, we propose our aluminum fin deterioration prevention coating, "Polyual." 【Brighgold's Solutions】 ■ World-leading technology used in 50 countries for 30 years ■ A protective agent specifically for aluminum fins, ensuring effective protection ■ High thermal conductivity to maintain and restore the performance of aluminum fins ■ Repairs through touch-ups to protect fins semi-permanently *For more details, please refer to the PDF document or feel free to contact us.

[Polyurethane Construction Proposal] Indoor Equipment Measures for Food Manufacturing Facilities

[Polyurethane Construction Proposal] Indoor Equipment Measures for Food Manufacturing Facilities

Proposal for the installation of polyurethanes to prevent deterioration caused by salt and corrosive gases!

"Polyual" is a corrosion prevention coating for aluminum fins patented by Blygold. It is known that in working environments such as pickle manufacturing, seafood processing, cyanide fumigation warehouses, fermentation equipment for beer, sauce production, mushroom cultivation, photo development equipment, and hair salon permanents, the deterioration of indoor units is severe. Regular and careful maintenance of air conditioning indoor units primarily involves cleaning, and measures against salt and corrosive gases are not taken. In such operations, the generation of gases that corrode aluminum often leads to the resignation of replacing fins every three years, and many people opt to install expensive stainless steel or copper fins. By applying our product, a coating film is formed on the surface of the aluminum fins, helping to prevent deterioration. [Features] - Suppresses the growth of bacteria and mold on aluminum fins of heat exchangers - Addresses heat exchangers that cannot be protected even with cationic coatings - Protects outdoor units in salt damage areas where salt damage occurs even with heavy salt damage specifications - Repairs through touch-up, providing semi-permanent protection for fins - Maintains high thermal conductivity, allowing for thick coating films and heat exchange performance, etc. *For more details, please refer to the PDF document or feel free to contact us.

Comparison with stainless steel fins and copper fins

Comparison with stainless steel fins and copper fins

Comparing "stainless steel fins," "copper fins," and "polyural"! Detailed explanation provided.

Stainless steel fins deteriorate under severe salt damage conditions, and their low thermal conductivity is well known. Copper fins excel in thermal conductivity due to their close contact with copper tubes, but they are expensive, and the salt resistance of copper is not much different from that of aluminum, resulting in a deterioration rate that is said to be about half that of standard aluminum fins (deterioration between dissimilar metals can be avoided). Under conditions where standard aluminum fins deteriorate in three years, copper fins will deteriorate in about five to six years. Therefore, we propose our aluminum fin deterioration prevention coating, "Polyual." 【Features of Polyual】 ■ Provides semi-permanent protection ■ Maintains and restores the initial performance of fins ■ Effectively protects the air conditioning unit from salt damage and polluted gases ■ Protects thoroughly from the inside of the fins to the ends ■ Shuts out the intrusion of salt damage and pollution *For more details, please refer to the PDF document or feel free to contact us.

Can it be overcoated with cation?

Can it be overcoated with cation?

A detailed explanation of whether topcoating can be done on cationic electrodeposition coating!

We often receive inquiries about whether it is possible to apply a topcoat over cationic electrodeposition paint. The answer is yes, and there are successful cases. However, when a topcoat is applied over cationic paint, the adhesion is dominated by the cationic layer, which is prone to cracking. If the cationic coating cracks or peels, the topcoat may also tear, and in this case, it will not be covered by warranty. Using a thin pre-coat film with salt damage resistance reduces the risk, but the adhesion will still be weaker compared to painting directly on aluminum or copper. Considering the costs, we recommend painting directly on aluminum or copper. *For more details, please refer to the PDF materials or feel free to contact us.*

Comparison with cationic electrodeposition

Comparison with cationic electrodeposition

Comparing "cationic electrodeposition" and "polyurethane"! A detailed explanation will follow.

Cationic electrodeposition is an excellent rust prevention technology; however, in the case of heat exchangers, a film thickness of 20 microns, which is expected to provide sufficient rust prevention, can affect thermal efficiency, leading to an increase in electrical material quantity and potentially requiring larger equipment. Therefore, we propose our aluminum fin deterioration prevention coating, "Polyual." 【Comparison】 <Cationic Electrodeposition / Polyual> ■ Application: At manufacturing / At manufacturing, installation site - Since thinner is used for Polyual application, if installed indoors, painting must be done outdoors before installation. ■ Film thickness: 8–30 microns / 20–25 microns ■ Thermal conductivity: Low / High - Polyual has thermal conductivity equivalent to aluminum. ■ Repairability: Not possible / Possible *For more details, please refer to the PDF document or feel free to contact us.

The necessity of the aluminum fin deterioration prevention paint "Polyual."

The necessity of the aluminum fin deterioration prevention paint "Polyual."

A detailed explanation of environmental factors that induce malfunctions and the importance of air conditioning units!

Environmental factors that significantly impact the performance and lifespan of heat exchangers in outdoor units of air conditioning systems include not only salt damage and volcanic gases from hot springs but also acid rain, exhaust gases, and various airborne impurities from agricultural and industrial production. On the other hand, it is said that many malfunctions in air conditioning equipment stem from heat exchangers and aluminum coils, and failures in components like compressors are often caused by performance degradation of the heat exchangers or overload due to clogging. Maintaining the heat exchangers of outdoor units, which process an amount of air equivalent to a full Tokyo Dome in just one week, is directly linked to the longevity of the air conditioning units, especially when compared to the heat exchange devices of indoor units that are protected by filters. Therefore, we propose our aluminum fin deterioration prevention coating, "Polyual." **Features of Polyual:** - Provides semi-permanent protection - Maintains and restores the initial performance of fins - Effectively protects the functionality of air conditioning units from salt damage and polluted gases - Thoroughly envelops the fins from the inside to the edges for protection - Shuts out the intrusion of salt damage and pollution *For more details, please refer to the PDF document or feel free to contact us.*

Comparison with precoat

Comparison with precoat

Comparing "Precoat" and "Polyural"! Detailed explanation to follow.

The outdoor units designed for salt damage resistance and heavy salt damage resistance use aluminum fins that are pre-coated with a polymer, which protects the aluminum from salt damage and other hazards. However, while the thickness of the Polyual membrane is 20 to 25 micrometers, the pre-coat is only about 2 to 3 micrometers thick. After being exposed to salt damage for 3 to 5 years, rust may occur, or the pre-coat membrane may degrade due to ultraviolet rays. Additionally, since the pre-coat involves processing aluminum sheets coated with polymer, the cut surfaces, internal cutouts, and contact points with copper pipes are exposed to the outside air, making them entry points for salt damage and corrosion. The aluminum fin deterioration prevention coating "Polyual" addresses these issues. [Overview] The Polyual coating membrane is applied after the heat exchanger assembly, ensuring that both the contact points with the copper pipes at the fin tips and the internal cutout areas are well protected. In the salt damage specification pre-coat, these areas are exposed to outside air. *For more details, please refer to the PDF materials or feel free to contact us.
