In the modern electronics industry, precision manufacturing and efficient assembly are key to product quality. Whether it’s smartphones, tablets, or industrial devices, a reliable material is needed to ensure the stability and durability of the components. Adhesive sealant, as a multifunctional material, is widely used in the electronics industry due to its excellent performance. This article will delve into the characteristics, application scenarios, and how to choose suitable products for adhesive sealants, providing practical references for industry practitioners.
1、 What is adhesive sealant?
Adhesive sealant is a polymer material that combines bonding and sealing functions, usually made of substrates such as silicone, polyurethane, epoxy resin, etc. It has excellent weather resistance, chemical corrosion resistance, and good mechanical strength, and can maintain stable performance in high temperature, low temperature, or humid environments.
In the electronics industry, the main functions of adhesive sealant include:
Adhesive fixation: firmly fix electronic components in designated positions to prevent loosening or detachment.
Sealing protection: prevents moisture, dust, and other pollutants from entering the interior of the equipment, extending the product’s lifespan.
Insulation and thermal insulation: Provide electrical insulation and thermal management functions to ensure the safe operation of equipment.
2、 Application of adhesive sealant in the electronics industry
With the diversified development of electronic products, the application scenarios of adhesive sealants are becoming increasingly diverse. Here are several typical application areas:Smartphones and tablets
Phone case sealing
In the production process of smartphones and tablets, adhesive sealant is used for bonding screens and borders, fixing camera modules, and sealing battery compartments. These parts require extremely high transparency, flexibility, and durability of the adhesive, and high-performance silicone or UV cured adhesives can perfectly meet the needs.
LED display screens and lighting equipment
LED shell sealing
LED display screens and lighting equipment need to be exposed to outdoor environments for a long time, so there are strict requirements for the weather resistance and waterproof performance of sealants. Polyurethane sealant and silicone sealant have become the preferred materials in this field due to their excellent UV resistance and high and low temperature resistance.
Industrial control equipment
Sealing of industrial equipment casing
Industrial control equipment typically operates in harsh environments such as high temperatures, high humidity, or dusty environments. Adhesive sealant can effectively block external pollution and provide seismic buffering function, ensuring long-term stable operation of equipment.
Electronic systems for new energy vehicles
Sealing of automotive parts shell
Key components such as battery packs, sensors, and controllers in new energy vehicles need to be sealed and fixed with adhesive sealant. This type of glue not only needs to have high-strength adhesive force, but also needs to have good thermal conductivity and flame retardant properties.
3、 How to choose a suitable adhesive sealant?
Faced with numerous adhesive sealant brands and models on the market, how to choose the appropriate product is a question that every engineer needs to consider. Here are a few key factors:
Environmental certification
Many countries and regions have increasingly high environmental requirements for electronic products, making it particularly important to choose adhesive sealants that comply with standards such as RoHS and REACH.

Material compatibility
Different electronic components may be made of metal, plastic, glass, or composite materials, so it is necessary to choose adhesives compatible with the substrate to avoid problems such as cracking and delamination.
Curing method
According to different production processes, sealant that can be cured at room temperature, heat cured, or UV cured can be selected. UV cured adhesive is particularly suitable for assembly line operations in rapid production.
Performance indicators
Focus on parameters such as adhesive strength, temperature resistance, chemical resistance, and thermal conductivity of the glue. For example, equipment working in high-temperature environments should choose high-temperature resistant sealant.
