The picture on the left is a waterproof and breathable component with a support body, and the picture on the right is a waterproof and breathable component with pure e-PTFE membrane

1. General guidelines

When installing adhesive-backed waterproof and breathable products on the shell, the following comprehensive factors are very important.

Shell surface smoothness

Cleanliness of housing mounting surface

Surface profile of housing mounting surface

The surface energy of the housing mounting surface

Dwell time during application and cure time after application

2. Storage suggestions

Waterproof and breathable products should be stored indoors in a controlled environment for up to one year

Recommended storage conditions are a temperature of 21°C and a relative humidity (RH) of 50%

Store in original packaging and keep the environment clean

Avoid direct sunlight and keep away from heat sources —

3. Operation Guide

Operators should wear latex-free gloves or finger cots when handling adhesive-backed breathable products

Avoid direct contact with the product’s effective ventilation area (Figure 1) or adhesive ring

Keep all sharp or jagged items away from expanded polytetrafluoroethylene (e-PTFE) breathable membrane

4. Guide to removing the patch

The inner diameter of the backing paper roll is 76.2 mm

Waterproof and breathable products can be removed manually or with automatic equipment

To prevent damage to the product, do not pry the product away from the backing paper roll

When removing it manually, slowly roll up the liner under the waterproof and breathable product along the edge until the product is separated from the liner for use.

Use blunt-edged tweezers to remove the product from the pad (Figure 2)

5. Installation Guide

Ensure the vent and housing temperature is above 10 °C

Make sure the mounting surface of the enclosure is smooth, clean and free of oil, particles or other contaminants. No jagged or sharp edges that could damage the waterproof breathable product

The housing mounting surface can be cleaned with isopropyl alcohol

Before installing waterproof and breathable products, ensure that the housing installation surface is dry

A hole of at least 1 mm is usually recommended

Larger diameter vents may require multiple 1 mm holes (Figure 3)*

6. Positioning

Pure membrane type waterproof and breathable products can be installed on the inner or outer surface of the shell

Series products with a support layer can only be installed on the inner surface of the housing, with the side with the breathable membrane facing the outside (liquid)

Place the product along a flat vertical surface without water or other dirt accumulating on the surface.

You can mark or demarcate the “target area” on the shell where waterproof and breathable products are required to improve the accuracy of placing waterproof and breathable products.

Use the target box as a guide to place the waterproof and breathable products within the box

Note:For corrosive environments, a raised target zone around the vent installation location may help prevent damage to the vent edges.
7. Pressing – suitable for semi-automatic systems

For excellent press head design and proper application pressure, follow these general recommendations:

The press head should be made of soft rubber (hardness 20 – 40 Shore A) with a uniform thickness and a thickness of at least 5.0 mm

The press head should be perpendicular to the housing mounting surface and positioned to apply pressure to the target/ guard ring

According to the size of the adhesive ring, apply a uniform pressure of approximately 2.07 bar on the adhesive area of the waterproof and breathable product. The force on the surface of the pressing head should be appropriate to prevent pressure on the breathable area of the waterproof and breathable product.

The dwell time of the pressing head should exceed 5 seconds

Leave it for 24 hours before starting to use or test it

These steps are necessary to ensure that the product adheres firmly to the case

8. Pressing – suitable for manual installation<&== &span>

Make sure the entire adhesive ring is close to the surface of the case

Use your fingers to gently press at least two circles along the circumferential area of the adhesive ring to ensure that the waterproof and breathable product is firmly bonded to the shell. Be careful not to touch the center of the breathable area (Figure 5)

Leave it for 24 hours before starting to use or test it

These steps are necessary to ensure that the product adheres firmly to the case

9. Final inspection

If a target ring is used, the product should be completely within the target frame and not pressed against the frame walls

Once installation is complete, the product should not be relocated

Damage can occur when venting products are removed from the mounting surface

Industry application

Gas sensor

Adhesive Vents Membrane, Vents Membrane,waterproof breathable membrane,waterproof breathable film for car lights

Prevent fog and condensation: While the car is driving, the surface of the headlights is easily affected by temperature changes and humidity. , causing fog or condensation inside the headlights. The breathable cap can allow air to circulate inside the lamp through the breathable holes, allowing internal moisture to be quickly discharged, effectively preventing fog and water vapor from condensing, and improving driving safety.
Protecting lamp components: The breathable cap keeps the inside of the lamp dry while also preventing external liquids from entering. , such as rain or water spray during car washing, thereby effectively protecting the electronic components and circuits inside the lamp and extending the service life of the lamp.
Reducing pressure differences: Temperature changes will cause differences in air pressure inside and outside the lamp. The design of the breathable cap can Balance the internal and external air pressure to avoid damage to the sealing structure of the lamp due to differences in air pressure.
Increase heat dissipation effect: The vent design of the breathable cap helps promote the dissipation of heat inside the lamp. Reduce the operating temperature of the lamp and improve the stability and reliability of the lamp.

In summary, the application of breathable caps can effectively prevent fog and water vapor condensation, protect lamp components, balance internal and external air pressure, and increase heat dissipation, thereby improving the performance and reliability of car headlights. Provide guarantee for driving safety.

Security equipment

Waterproof and breathable: The breathable membrane has waterproof and breathable properties, which can effectively prevent water and moisture from entering. Inside the device, it also allows water vapor inside the device to be discharged through the breathable membrane, thereby maintaining a dry environment inside the device. This is especially important for outdoor security equipment and can increase the service life of the equipment.
Dust and anti-fouling: The breathable membrane can prevent dust, particles and pollutants from entering the interior of the device, while Allows moisture inside the device to escape through the breathable membrane. This helps keep equipment clean and reduces the frequency and cost of cleaning and maintenance.
Reduce temperature changes: The breathable membrane can help balance the temperature inside and outside the device, preventing the device from being damaged due to temperature changes. A pressure difference is created, thereby reducing the risk of damage to internal components of the device. Especially in high-temperature environments, the breathable membrane can release heat and maintain the normal operating temperature of the device.
Prevent air pressure build-up:The breathable membrane can help balance the air pressure inside and outside the device and prevent air pressure from building up inside the device. Causing instability or disruption. This is very critical for some closed equipment or security equipment in explosive hazardous environments.

In general, the application of breathable membranes in security equipment has the advantages of waterproof and breathable, dustproof and antifouling, temperature balance and air pressure balance. It can keep the inside of the equipment dry and clean, reduce maintenance costs, and also improve the stability and service life of the equipment.
