What adhesive is used for bonding electronic component shells? ——PUR 1680 (D70) A/B polyurethane sealant professional solution

Against the backdrop of the continuous development of electronic products towards lightweight, high reliability, and extreme environmental resistance, shell bonding and internal encapsulation have become key factors affecting the stability of electronic devices. Whether it is communication equipment, sensors, control power supplies, or ignition controllers, internal components all face challenges such as humidity, vibration, temperature shock, electrical interference, and outdoor exposure. In order to enhance the overall assembly strength and protect internal components, Yilian has launched PUR 1680 (D70) A/B high hardness polyurethane sealant, specifically designed for bonding and sealing electronic component housings.1、 Core advantages of PUR 1680 (D70) A/B polyurethane sealant

Solution for wiring harness board sealing with adhesive | SIPA 1850 gray two-component addition molding silicone

In the continuous upgrading of new energy vehicles, energy storage equipment, and intelligent manufacturing equipment, the stability of the wire harness PCB directly determines whether the system can operate stably in complex environments such as high temperature, vibration, and humidity for a long time. In order to ensure the weather resistance and reliability of the wiring harness board, the encapsulation process has become an indispensable part. Adhesive for wiring harness board sealing In the face of changing application environments, engineers often make the following requirements for sealant:✔ Having certain thermal conductivity to avoid heat accumulation affecting the lifespan of electronic components✔ The adhesive strength does not need to be too high, but it should maintain flexibility and fatigue resistance✔ Two…

Micro switch waterproof sealing solution | PUR 1680 polyurethane foam adhesive

Micro switches are widely used in precision electronic components such as automotive electronics, smart home appliances, industrial control, etc. due to their small size, sensitive triggering, and high reliability. However, due to its compact internal structure and sensitive electrical contacts, it is prone to switch failure, contact oxidation, and sensitivity reduction in humid, vibrating, or chemical environments. Therefore, waterproof sealing protection has become a key link to ensure the long-term stable operation of micro switches. Application challenge: PP shell+long-term sealing, failure to stick firmly is ineffective protectionThe housing of micro switches is often made of PP (polypropylene) material, which has low surface energy and strong inertness. Even after plasma treatment, many adhesives still exist:✅ Insufficient adhesion, cracking occurs under slight…

Waterproof Adhesive Solution for Automotive Lights – SIPC 1859 Organic Silicon

In the automotive industry, waterproof bonding of car lights is an important part of ensuring long-term stability of lighting fixtures. Optical components such as headlights, taillights, and daytime running lights are prone to problems such as water leakage, delamination, or PC material aging in harsh environments such as high temperature, humidity, and ultraviolet radiation if they lack effective waterproof bonding protection. Elapluus car lamp waterproof bondingCore requirements for waterproof bonding of car lightsWhen carrying out waterproof bonding of car lights, the following key performance should be paid attention to:Efficient bonding of PC materials: Car lamp covers are mostly made of polycarbonate (PC) material, and the adhesive needs to ensure long-lasting and strong adhesion.Non flowing and de methanol: During the construction…

Silicon gel for pressure sensor potting – high viscosity, high reliability and high protection

In the packaging protection of pressure sensors, the fluidity, viscosity, and stress release ability of the sealing adhesive often determine the long-term stability and reliability of the sensor. Especially in the face of complex environmental conditions (high humidity, high temperature, mechanical vibration), it is particularly important to select a suitable silicon gel. Today, we recommend a high-performance potting material SIGEL 1805 two-component addition molding silicon gel specially designed for pressure sensors, MEMS chips and precision circuit modules. Load cell gel encapsulation Load cell gel encapsulation1、 Product Features Highlights✅ Soft and elastic, excellent cushioningAfter curing, it forms a soft elastic body that can release mechanical stress under thermal cycling and vibration conditions, protecting the chip and leads from damage.✅ Excellent electrical…
