Henkel’s Loctite SI 5972FC – Fast-Curing RTV Silicone Gasket for Automotive Electronics
Henkel has introduced Loctite SI 5972FC, a one-part RTV silicone form-in-place-gasket (FIPG) designed to accelerate automotive electronic module sealing. This solution enables immediate leak testing post-assembly, significantly reducing staging time and optimizing production efficiency.
Key Benefits & Features:
- Fast curing: Passes 3-psi leak test immediately after assembly, with higher pressure resistance in short timeframes.
- Versatile adhesion: Bonds to both metal and plastic surfaces.
- Safe & sustainable: Uses a tin-free catalyst system, making it REACH-compliant and environmentally friendly.
- Non-corrosive & low volatility: Ensures safety for sensitive electronic components (D4-D10 <0.1%).
- Dispensable & energy-efficient: Eliminates the need for curing ovens, reducing energy usage and carbon emissions.
Applications:
Ideal for sealing automotive electronic modules, including:
- Electronic Control Units (ECU)
- Bussed Electric Centers (BEC)
- Battery Disconnect Units (BDU)
- Electrical Power Steering (EPS) Power Packs
- ADAS (Radar) components
Industry Impact:
This innovation supports the automotive industry’s shift toward EVs and autonomous vehicles, reducing waste, energy consumption, and emissions across the supply chain.
Henkel continues to pioneer cutting-edge gasketing solutions that enhance performance, reliability, and sustainability in automotive electronics manufacturing.
