With the rapid advancement of intelligence and networking, the complexity and density of automotive electronic systems continue to increase, and electronic connectors, as the core connecting components, are facing higher requirements for sealing, reliability, and durability. Today we will share a practical case where we successfully solved the problems of fluidity and adhesive operation in joint reinforcement by selecting the appropriate sealant.
Customer Background: Challenges for Automotive Electronics Manufacturers
The client is a Tier 1 supplier of automotive electronics, with a long-term focus on the research and manufacturing of high-end intelligent control systems. Its electronic connector is located in the engine control unit wiring harness area and is exposed to complex environments such as alternating cold and hot, moisture, and vibration for a long time. The original adhesive solution exposed two problems in actual mass production:
The viscosity of the glue is too high, making it difficult to accurately apply it to a 3mm wide slot;
The curing speed is slow, the efficiency is low, and it affects the production line rhythm.
The customer explicitly requested a low viscosity, self leveling, easy to operate, and reliable sealing solution for the sealant.
List of adhesive requirements
Requirements for adhesive application scenarios
The reinforcing glue at the end of the joint needs to have good fluidity and permeability
Glue with a width of 3mm needs to have self leveling characteristics, and there should be no residue during fine operation
Easy to operate, suitable for manual or automated dispensing systems
Long term reliability to resist moisture, dust, and electrical interference, ensuring electronic stability
Recommended solution: RTV SIPC 9030 self leveling sealant
In response to the above pain points, we recommend using RTV SIPC 9030 silicone sealant for our customers. This is a neutral dealcoholized, single component RTV silicone sealant developed specifically for PIN needle sealing, connector protection, and other scenarios, especially suitable for sealing and bonding metal coatings and magnetic materials.
✅ Core advantages of the product:
Good self leveling performance: can flow into narrow gaps, achieving comprehensive coverage;
Low viscosity and easy to apply glue: Whether it is a 3mm slot or a complex structure, it can be applied smoothly;
Neutral curing is safer: it does not corrode common metal materials such as copper, tin, silver, etc;
Excellent electrical insulation: protects circuits from interference and prevents corona breakdown;
Long aging resistance and lifespan: The outdoor service life can reach 20-30 years;
Wide temperature adaptability: Maintain stable performance at -60 ° C~260 ° C.
The sealing of automotive electronic connectors is never just about being able to stick. It needs to cope with complex environments such as high temperature, humidity, vibration, and frequent connections. SIPC 9030 is a sealant product designed for “high reliability”. It is not only user-friendly, but also has excellent long-term stability. It has been widely used in multiple projects such as new energy vehicles, in car sensors, connectors, etc.
