Engineering Applications of Silicone Sealing
1. Industrial Assembly
Used in vehicle bodywork, appliance assembly, and electric motor housing. Supex 280 and Supex 4005 offers excellent adhesion to both metals and plastics.
2. Electronics & PCB Protection
Neutral cure silicone sealing encapsulate components without corroding metal contacts. Ideal for moisture and thermal protection. Supex 596 FL.
3.Transportation
Marine, aerospace, and rail sectors rely on neutral silicones for sealing and vibration control in extreme conditions.
4. HVAC Systems
Sealing duct joints and metal fittings. Products like Supex Neutral+ ensure flexibility across temperature ranges.
5. Facade Sealing
Seals joints between concrete panels or aluminum cladding. Supex WP+ is excellent for absorbing movement while remaining watertight.
