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 can lead to unexpected increases in electricity consumption and sudden high-pressure cuts, resulting in operational losses. Issues with air conditioning and refrigeration equipment can significantly impact management. Microchannel heat exchangers have very fine piping through which the refrigerant passes, making it difficult to detect leaks when they occur, as small amounts of refrigerant leak slowly. By the time you notice it, there may already be an increase in electricity consumption and further operational losses. Therefore, we propose our aluminum fin deterioration prevention coating, "Polyual." 【Brighgold's Solution】 - World-leading technology used in 50 countries for 30 years - A protective agent specifically for aluminum fins, ensuring reliable protection - High thermal conductivity that maintains and restores the performance of aluminum fins - Repairs through touch-up, providing semi-permanent protection for the fins *For more details, please refer to the PDF materials or feel free to contact us.

Polyurethane for preventing refrigerant leakage.

We recommend Polyurethanes for preventing leaks in heat exchangers.

About half of the heat exchangers we are currently painting are for the purpose of preventing refrigerant leakage. In an atmosphere containing acids, sulfur, and ammonia, corrosion occurs in the copper pipes of the vent section, leading to pinholes and resulting in refrigerant and Freon leakage. Polyurethane prevents the occurrence of corrosion, thereby preventing Freon leakage. Although measures against Freon leakage are being tightened, we recommend polyurethane 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; therefore, as a general 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 of 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 employed to protect aluminum fins. However, the thin salt-resistant and heavy salt-resistant specifications, which are only a few microns thick, deteriorate and peel off almost entirely within a year under direct sunlight. The aluminum fin deterioration prevention paint "Polyual" is 20 microns thick, similar to Okinawa coating, making it less susceptible to UV damage and providing long-lasting durability. **Brighgold's Solutions** - World-leading technology used in 50 countries for 30 years - A protective agent specifically for aluminum fins that reliably protects the fins - High thermal conductivity maintains and restores the performance of aluminum fins - Outdoor units in use can also be coated - Touch-up repairs provide semi-permanent protection for the fins *For more details, please refer to the PDF document or feel free to contact us.*

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, it is possible and there are proven results. However, when a topcoat is applied over cationic paint, the adhesion is dominated by the cationic layer. If the brittle cationic coating cracks or peels, the topcoat may also tear, and in such cases, 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 direct painting 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

Comparing "cationic electrophoretic painting" and "polyurethane"! Detailed explanation to 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 effect, 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 and installation site - Since thinner is used for Polyual application, if installed indoors, it will need to be painted 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.

Comparison with stainless steel fins and copper fins

Comparing "stainless steel fins," "copper fins," and "polyural"! A detailed explanation will follow.

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 significantly 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 would 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's function from salt damage and polluted gases ■ Thoroughly envelops and protects the fins from the inside 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.
