Product Overview
Our Electronics Encapsulation Sealing Insulation silicone is a professional solution for electronic component protection, composed of high-purity flowable Part A (base rubber) and Part B (curing agent) via advanced addition curing technology. It solves the pain point of ordinary encapsulation materials (such as epoxy or low-grade silicone) with poor insulation, weak sealing, poor temperature adaptability, and damage to sensitive electronic components. Unlike standard
Mold Making Silicone, our product is specially formulated for electronic encapsulation—curing into a compact, insulation-rich elastic body, ideal for encapsulating, sealing, and insulating electronic components, circuit boards, sensors, and connectors, ensuring long-term stable operation.

How to Use (Step-by-Step Guide)
1. Mix Part A and Part B of the encapsulation silicone in a 1:1 weight ratio, stirring thoroughly in an irregular direction for 2~3 minutes until uniform and bubble-free (ensuring insulation and sealing performance).
2. Perform vacuum degassing for 2~5 minutes (time varies by viscosity) to eliminate bubbles, avoiding insulation defects in encapsulated components.
3. Pour or coat the degassed silicone precisely onto electronic components/circuit boards, leveraging good fluidity to fill gaps and cover sensitive parts.
4. Cure at room temperature (25℃) for 4~5 hours, or 80~120℃ for accelerated curing; post-cure enhances insulation and adhesion.
5. Store unused silicone in sealed packaging, separate Part A and Part B, indoor storage away from sunlight and rain, use within 10 months; avoid contact with N, P, S-containing compounds to prevent curing failure.
Application Scenarios
Our Electronics Encapsulation Sealing Insulation silicone is widely used in global electronic fields, including electronic component encapsulation, circuit board sealing, sensor insulation, automotive electronic protection, industrial control device encapsulation, and connector sealing. It is suitable for electronic component manufacturers, automotive electronics suppliers, and industrial control equipment producers, bringing tangible value: reducing component failure rate by 55%+, extending product service life by 40%+, and helping B2B purchasers improve product reliability and market competitiveness.
