In today’s demanding industrial and commercial environments, choosing the right sealing and bonding solution is critical. Whether it’s for electronics, automotive, construction, or LED applications, clear RTV silicone adhesive and silicone sealants have become indispensable.
Fasto Adhesives offers high-performance solutions designed to deliver durability, flexibility, and superior sealing performance across multiple applications.
What is Clear RTV Silicone?
Clear RTV (Room Temperature Vulcanizing) silicone is a type of silicone sealant that cures at room temperature to form a flexible, durable, and waterproof rubber.
Key Characteristics:
- Transparent appearance for aesthetic applications
- Excellent adhesion to glass, metal, plastic, and ceramics
- High temperature resistance
- Waterproof and weatherproof
- Non-corrosive and UV resistant
This makes it ideal for applications where visual clarity and performance both matter.
What is RTV Silicone Adhesive?
RTV silicone adhesive is a versatile bonding and sealing material that cures into a rubber-like consistency.
Unlike traditional adhesives, RTV silicone:
- Maintains flexibility after curing
- Absorbs vibrations and thermal expansion
- Provides long-term durability under harsh conditions
Common Types:
- Acetoxy Cure RTV – Fast curing, strong adhesion (used in general sealing)
- Neutral Cure RTV – Non-corrosive, suitable for sensitive materials like electronics
Applications of RTV Silicone Adhesives
1. Electronics & LED Industry
- Sealing LED drivers and modules
- PCB protection against moisture and dust
- Insulation and vibration resistance
2. Automotive Industry
- Gasket making
- Engine sealing
- Resistance to oil, heat, and pressure
3. Construction & Infrastructure
- Glass bonding and sealing
- Expansion joints
- Weatherproofing applications
4. HVAC & Industrial Systems
- Duct sealing
- Equipment insulation
- Leak prevention
What are Silicone Sealants?
Silicone sealants are high-performance materials used to seal joints and gaps to prevent the passage of air, water, or contaminants.
They are widely used because of their:
- Long lifespan
- Elasticity
- Resistance to extreme weather conditions
Types of Silicone Sealants:
- General Purpose Sealants – For basic sealing needs
- Structural Silicone Sealants – For load-bearing applications
- High-Temperature Sealants – For industrial and automotive use
- Clear Silicone Sealants – For aesthetic and transparent finishes
