RTV Silicone Adhesive for PCB Board sealing

  • RTV Silicone Adhesive for PCB Board sealing

    Short Introduction 

    Our PCB RTV Silicone Adhesive is a single-component room-temperature vulcanizing silicone compound, specially formulated for electronics manufacturing. It extrudes like toothpaste and cures at ambient temperature to form a resilient silicone rubber layer. Available in transparent, white and black to meet diverse visual and application requirements. Perfect for bonding, sealing and coating PCB assemblies and electronic components.


    ✦ Core Key Benefits

    ☑ Excellent Insulation & Circuit Protection High dielectric strength prevents short circuits and safeguards delicate electronic parts from electrical breakdown.

    ☑ Waterproof & Moisture Proof Fully cured silicone forms a tight, flexible barrier to block water vapor, humidity and contaminants, ideal for outdoor and humid environment electronics.

    ☑ Thermal Shock Resistant Withstands repeated temperature cycling without cracking, peeling or losing elasticity. Maintains performance under hot and cold fluctuations.

    ☑ Dual Performance: Bonding + Elastic Sealing Functions both as an adhesive to fix components and a flexible elastomer to absorb vibration and stress.

    ☑ Easy Room Temperature Curing No oven heating required. Simply extrude directly from the tube, cures naturally at room temperature for convenient on-site operation.

    ✦ Typical Applications

    ▣ PCB circuit board sealing, protection and conformal coating ▣ LED light strip bonding & encapsulation ▣ Electronic component fixing and shock absorption ▣ Power supply, sensor and control module sealing ▣ Automotive & industrial electronic assembly
