Nowadays, many machinery and instruments require water, moisture, and corrosion resistance to achieve longer service life. Dry film oil has become a widely used lubricant in the industry, capable of meeting these consumer demands. Dry film oil is a specially formulated, clean, dry-film lubricant. After drying, this fast-drying lubricant forms a transparent, dry, and non-sticky lubricating coating on the surface of the workpiece. Below, we explore the performance features of dry film oil together with the technical experts from EUBO.
Dry Film Oil
Versatile Surface Penetration and Bonding
Dry film oil can penetrate and bond to surfaces of metals, paper, wood, rubber, plastics, glass, and most other components requiring lubrication. It forms a non-sticky lubricating film that prevents direct contact between friction surfaces, thereby reducing wear.
Excellent Wear Resistance and High-Temperature Performance
Offers outstanding wear resistance, water resistance, and acid/base wash resistance, and can withstand temperatures up to 380°C.
Non-Flowing and Dust-Resistant Film
The coating does not flow, does not attract dust or dirt particles, is non-flammable, odorless, and highly safe.
Excellent Thermal and Chemical Stability
When applied to electronic components, it can naturally form an insulating layer. For parts where oils or other lubricants cause contamination, curing, or viscosity changes that prevent proper lubrication, dry film lubricants are the ideal solution.
Additional Key Features
Resistant to dust, low torque, suitable for high and low temperatures, non-oily, noise-reducing, and addresses issues such as diffusion and contamination associated with traditional oil-based lubricants.
In addition to the points mentioned above, dry film oil possesses many other performance advantages that are not listed here.

PUR Hot Melt Adhesive (full name: moisture-curable reactive polyurethane hot melt adhesive) is a high-performance adhesive that is solid at room temperature and melts into a liquid upon heating. Its unique reactive curing mechanism allows it to rapidly cure under the influence of ambient moisture, forming a strong chemical structure. PUR hot melt adhesive exhibits excellent adhesion to a wide range of materials, including metals, plastics, glass, and rubber, and is widely used in fields such as lithium batteries, automotive, and home appliances.
Reasons for Using PUR Edge-Folding Adhesive in Polymer Lithium Batteries
In traditional pouch cell manufacturing, the edges of the cells are sealed with adhesive tape to maintain the cell’s appearance and dimensions, as well as to prevent external short circuits. While this method is effective, the increasing demand for higher energy density in lithium batteries has led to the gradual replacement of tape sealing with adhesive-based edge-folding processes. The adhesive edge-folding process optimizes the battery structure, improving volumetric energy density while reducing production costs. This new process not only enhances production efficiency but also increases automation levels on the production line and improves the yield of quality products.
The application of PUR edge-folding adhesive in this new process addresses the limitations of traditional edge-sealing methods in terms of stability and production efficiency, making it the preferred solution for side bonding in polymer lithium batteries.
Advantages of EUBO PUR Edge-Folding Adhesive
The main advantages of PUR edge-folding adhesive lie in its excellent high-temperature peel resistance and strong adhesion, ensuring secure bonding of battery sides even under high-temperature operating conditions and preventing bond failure. In addition, the adhesive features fast curing, low odor, and a solvent-free, environmentally friendly formulation. These properties not only meet safety and environmental standards but also enhance production line automation, reduce manual operations, and improve production efficiency and product yield.
Features of UR 6136 PUR Edge-Folding Adhesive
Excellent Adhesion: Provides outstanding bonding strength to various aluminum-plastic film substrates, ensuring dimensional stability of the battery.
High-Temperature and Weather Resistance: After curing, the adhesive maintains its strength under high-temperature conditions and exhibits excellent weather resistance, suitable for a variety of environmental conditions.
High Mechanical Performance: The cured PUR adhesive has good toughness, able to withstand vibration and mechanical stress, preventing bond failure due to external forces.
Environmentally Friendly and Solvent-Free: Formulated with 100% solid content and no solvents, compliant with environmental standards, with no harmful gas emissions, ensuring production safety.
Application Scenario:
The UR 6136 PUR adhesive is primarily used for side edge-folding bonding in polymer lithium batteries, ensuring stable cell edge sealing, preventing cell deformation or short circuits, and thereby enhancing battery safety and performance.
With the continuous development of industry, high-temperature greases are being used more widely, playing an especially important role in large-scale industrial equipment. However, during use, it is often observed that high-temperature grease gradually depletes. What causes this loss? Below, EUBO experts provide a detailed explanation.
The main causes of high-temperature grease loss include:
1. Internal Structure Degradation of the Grease
High-temperature grease, when exposed to heat and air over extended periods at friction points, can experience oxidation of the base oil and thickener, which damages the soap structure of the grease. This oxidation process causes the grease to soften, eventually leading to loss.
2. Impact of Operating Load
Continuous operation at friction points subjects high-temperature grease to constant shear stress, gradually damaging the thickener structure. Over time, the grease softens and is lost, significantly reducing its lubrication performance.
3. Environmental Factors
Metal particles generated during machinery operation can catalyze grease oxidation, producing organic acids that further compromise the stability of the grease, resulting in structural failure and loss.
These are the three main factors that lead to high-temperature grease loss. To prevent mechanical failures caused by grease depletion, high-temperature grease should be regularly inspected, replenished, or replaced. After all, the production losses resulting from equipment downtime due to lubrication issues far exceed the cost of routine maintenance.
