Engineering Applications of Silicone Sealing
1. Industrial Assembly
Silicone sealants bond metals and plastics in vehicle bodywork, appliances, and motor housings. Supex 280 and Supex 4005 deliver strong adhesion.
2. Electronics & PCB Protection
Neutral cure silicones protect components without corroding contacts. They guard against moisture and heat. Supex 596 FL fits this use.
3. Transportation
Marine, aerospace, and rail industries use neutral silicones for sealing and vibration control in harsh conditions.
4. HVAC Systems
Silicones seal duct joints and metal fittings. Supex Neutral+ maintains flexibility across temperature changes.
5. Facade Sealing
Silicones seal concrete and aluminum panel joints. Supex WP+ absorbs movement while staying watertight.
6. Glazing
Neutral cure silicones bond glass to frames in high-rise buildings. They offer flexibility and weather resistance.
7. Solar Energy Systems
Silicones seal solar panels and junction boxes. They resist UV and ensure long-term durability.
8. Firestop Systems
Special neutral silicones help maintain fire ratings in sealed structural penetrations.
