Elaplus SIPC UV 3301: High-efficiency Silicone Conformal Coating Solution for PCB

In the electronic manufacturing industry, the reliability of printed circuit boards (PCB) is the lifeline of electronic products. As electronic devices trend toward miniaturization and high integration, components on PCBs become increasingly densely arranged, making traditional single-cure conformal coatings face severe limitations. Conformal Coating for Gas Flow Meter One of the biggest challenges for engineers is shadow area curing dead zones. When UV light is blocked by tall components, the coating in shaded areas cannot cure completely, resulting in failed protection, short circuits, and even equipment corrosion. Today, we introduce Elaplus SIPC UV 3301, a UV/moisture dual-cure silicone conformal coating, and how it perfectly solves this industry pain point. I. Core Principle: Dual Curing Mechanism The key advantage of SIPC UV 3301 lies in its dual-protection curing design: Under UV irradiation at 300 mW/cm², the surface coating cures fully within 10 seconds to a tack-free state, greatly improving production line efficiency and throughput. 2.Moisture Secondary Curing (Full Shadow Cure) For shadow areas unreachable by UV light — such as component bottoms and pin gaps — the material absorbs atmospheric moisture to complete secondary curing. This mechanism ensures a tough elastic film forms in every gap of the PCB, completely eliminating risks caused by uncured residue. II. Extreme Temperature Resistance: -55℃ to 200℃ For automotive electronics, aerospace, and industrial automation equipment, drastic ambient temperature fluctuations are common operating conditions. SIPC UV 3301 delivers outstanding thermal stability: III. Excellent Electrical & Mechanical Properties SIPC UV 3301 excels in protective performance:Dielectric strength > 18 KV/mm, volume resistivity up to 3.5×10¹³ Ω·cm, providing reliable insulation protection under high-voltage working conditions. It also offers excellent shear adhesion to metals, glass, and various plastics including PC, ABS and PBT. Premium Applications: New Energy & High-end Manufacturing With its wide operating temperature range of -55℃ to 200℃,…
