Import Black Color Pcb Electronic Potting Silicone Hy 2 — Buy in Bulk from Supplier in China

The Black color PCB Electronic Potting Silicone HY 2 is a two-component, addition-cure silicone designed for encapsulating sensitive electronic circuits. It offers a dielectric permittivity of 3.0 to 3.3 at 1.2 MHz and a volume resistivity of 1.0 x 10^16 ohm·cm, ensuring robust electrical insulation for high-frequency applications. The compound achieves a UL 94 V-1 flame rating, providing moderate fire resistance for enclosed electronic assemblies.

This potting silicone adheres well to a variety of substrates, including epoxy glass laminates, metals, and engineering plastics, without requiring a primer for most surfaces. Its formulation allows for low-stress curing, which is critical for protecting delicate components like MEMS sensors or fine-pitch connectors. The material is also resistant to moisture, UV exposure, and thermal shock, making it suitable for outdoor or industrial environments.

Manufacturers in telecommunications, automotive electronics, and renewable energy systems use HY 2 for protecting power modules, control boards, and connectors. Its balance of electrical properties and mechanical durability makes it a versatile choice for applications where long-term stability is required. Buyers should confirm the exact curing conditions and post-cure properties to match their production workflow.

Hong Ye Jie Technology Co., Ltd. is based in Building A, No.3, Hongling First Road, Liulian Shibi, Pingdi Street, Longgang District, Shenzhen, Guangdong. The company is an imported-tier supplier with a harbor trust tier, indicating it meets baseline verification standards for cross-border trade. Its location in Shenzhen, a hub for electronics manufacturing, aligns with its specialisation in electronic materials.

The supplier’s profile shows no recorded response rate or average response time, which may indicate limited prior engagement. Buyers should contact the company directly to confirm current production capabilities, technical support, and quality control processes. The focus on electronic encapsulants suggests a narrow but deep expertise in potting and sealing solutions.
