Pulage Steel Cabinets' Climate Shield for Indonesian Environment

Electrostatic Powder Coating Technology: The "Climate Protection Shield" of Pulage Steel Filing Cabinets, the Core Code for Adapting to the Indonesian Environment

In Indonesia's climate environment characterized by perennial high temperature and humidity, salt spray in coastal areas, and termite infestation in inland regions, the "durability" of steel filing cabinets has long exceeded the simple requirement of "load-bearing" and become a core consideration for enterprises and institutions when purchasing. Electrostatic powder coating technology is precisely the "key technology" that enables Pulage steel filing cabinets to resist Indonesia's extreme climate and achieve long-term stable use—it not only endows products with excellent appearance and texture but also builds an all-round protective barrier. Pulage's proficient application and high-standard adherence to this technology have made its products stand out in the Indonesian market.

Electrostatic Powder Coating Technology: The "Advanced Protection Technique" for Steel Filing Cabinets

Electrostatic powder coating is an advanced surface treatment process. Its core principle is to charge dry powder coatings through an electrostatic generator so that they are uniformly adsorbed on the surface of grounded steel filing cabinet workpieces. Then, the workpieces are baked in a high-temperature curing oven (usually 180-200°C), where the powder particles melt, level and cure to form a dense and uniform protective film.

Compared with traditional spray painting processes, it has three core advantages that perfectly meet the usage requirements of steel filing cabinets:
1. Superior coating performance: The cured coating has extremely strong adhesion, with a hardness of over 2H, and outstanding scratch and impact resistance. Minor friction in daily office use will not easily leave marks; at the same time, the coating has no pinholes or bubbles, and its compactness is far superior to spray painting, which can effectively isolate external corrosive media such as moisture and oxygen.
2. Environmental protection and health: The whole process does not use solvent-based coatings and has no VOC (Volatile Organic Compounds) emissions. It neither pollutes the environment nor releases harmful gases like traditional spray painting, ensuring fresh air in the office and conforming to the concept of "green office" for modern enterprises.
3. Higher cost performance: The utilization rate of powder coatings is over 95%, and excess powder can be recycled and reused, reducing material loss; in addition, the coating has a long service life, no need for frequent repainting and maintenance, and the long-term use cost is lower.

The "Irreplaceability" of Electrostatic Powder Coating Technology in Indonesia's Climate Environment

Indonesia's climatic characteristics put forward "severe tests" for the surface treatment process of steel filing cabinets, and the characteristics of electrostatic powder coating technology precisely solve these pain points:
1. Resist high humidity and mold: Indonesia's annual relative humidity maintains at 75%-90%, especially in the rainy season and coastal cities (such as Jakarta and Surabaya). Humid air can easily penetrate traditional coatings, causing steel to rust, coatings to peel off, and then mold to breed, polluting internal documents. The dense coating of electrostatic powder coating can completely isolate moisture, and even in a high-humidity environment for a long time, there will be no "rust return" or "bulge" phenomenon, protecting the cabinet itself and internal documents from the root cause.
2. Combat salt spray corrosion: Indonesia has a long coastline, and the air in coastal areas contains a large number of salt spray particles, which are highly corrosive and can quickly erode the surface of ordinary steel, leading to rust spots and coating peeling on filing cabinets in a short period. The electrostatic powder coating technology adopted by Pulage has passed professional salt spray tests and can resist salt spray corrosion for more than 500 hours, far exceeding industry standards. Even when used in offices by the sea, it can maintain a good appearance for a long time.
3. Adapt to high temperature and temperature difference: The maximum daily temperature in Indonesia often exceeds 38°C. Although the day and night temperature difference is not extreme, long-term high temperature will accelerate the aging, fading and cracking of traditional coatings. Electrostatic powder coating has excellent high-temperature resistance, can maintain color stability and no coating cracking in Indonesia's high-temperature environment, and its service life is 3-5 times longer than that of traditional spray-painted filing cabinets.
4. Assist in termite prevention: Although steel itself does not attract termites, after traditional coatings fall off, wooden accessories or residual wood chips at steel joints may still become a "breakthrough" for termites. The complete coating of electrostatic powder coating can seal all gaps on the steel surface, preventing termites from contacting wooden components, and forming a double guarantee with the "termite-proof" characteristics of steel materials.

Pulage: Creating "Protective Grade" Filing Cabinets Adapted to Indonesia with Proficient Technology and High Standards

As a brand deeply rooted in Indonesia's office furniture market, Pulage is well aware of the importance of electrostatic powder coating technology for products to adapt to the local climate. Therefore, it has established a set of "super industry standard" control systems from raw material selection, process flow to quality inspection, demonstrating its proficient application and ultimate pursuit of this technology:

Strict selection of high-quality raw materials, controlling quality from the source

Pulage insists on using epoxy resin powder coatings that meet international standards. Such powders have stronger corrosion resistance, weather resistance and adhesion. Compared with ordinary polyester powders, their protective effect in Indonesia's high-humidity and salt spray environment is improved by more than 40%. At the same time, the cabinet base material uses high-quality cold-rolled steel plates with a thickness of 1.2-1.5mm to ensure that the base material itself is free of rust and impurities, providing a good foundation for subsequent spraying.

Refined pre-treatment process, building a "basic defense line" for spraying

70% of the effect of electrostatic powder coating depends on pre-treatment. Pulage has established six strict pre-treatment processes: degreasing → water washing → pickling → phosphating → passivation → drying: high-temperature degreasing removes oil and dust on the steel surface, pickling removes oxide scale, and phosphating forms a uniform phosphating film on the steel surface, which greatly improves the adhesion between the coating and the base material. Even after long-term high temperature and humidity, the coating will not fall off. This process has two more key procedures than the industry's conventional "degreasing → phosphating → drying", ensuring that every workpiece can meet the spraying standard of "zero impurities and high adhesion".

Advanced equipment and proficient technology to ensure uniform and dense coating

Pulage has imported German electrostatic spraying equipment and adopted a combination of "automatic spraying + manual touch-up spraying": automatic spraying ensures uniform coating on large areas of filing cabinets, and manual touch-up spraying accurately covers hidden parts such as corners and joints to avoid "missed spraying" and "thin spraying" problems. During the spraying process, technicians strictly control the powder charging voltage, powder output and spray gun distance to ensure that the powder is uniformly adsorbed on the workpiece surface, and the coating thickness is controlled at 60-80μm—this thickness can not only ensure protective performance but also avoid incomplete curing due to too thick coating.

Multiple quality inspections, adhering to "high-standard delivery"

Before leaving the factory, each batch of Pulage filing cabinets undergoes three core inspections: ① Adhesion test: no coating peeling after grid cutting with a hundred-grid knife and tape sticking; ② Salt spray test: no rust spots on the surface after 500 hours in a salt spray test chamber; ③ Weather resistance test: no fading or cracking of the coating after 1000 hours of exposure to simulated Indonesian high-temperature and high-humidity environment. Only products that pass all inspections can be put on the market.

It is Pulage's proficient application of electrostatic powder coating technology and adherence to high standards that have made Pulage steel filing cabinets widely recognized in the Indonesian market—whether in the salt spray environment of coastal cities or the high-temperature and high-humidity areas of inland, Pulage filing cabinets can maintain a good appearance and dry interior, effectively protecting enterprises' contracts, archives and other important documents, and becoming the preferred brand of "climate-adaptive" office furniture for Indonesian enterprises.

In the future, Pulage will continue to deepen the optimization and upgrading of electrostatic powder coating technology, continuously improve the protective performance of products in combination with subtle changes in Indonesia's climate, and provide more Indonesian enterprises with durable, safe and environmentally friendly office storage solutions based on "technology as the foundation and quality as the soul".
