High Temperature Surface Protection Silicone Heat Insulating Adhesive is a specially engineered, one-component RTV (room temperature vulcanizing) silicone adhesive designed for bonding, sealing, and insulating applications that require reliable performance under extreme heat.
Product Introduction
High Temperature Surface Protection Silicone Heat Insulating Adhesive is a specially engineered, one-component RTV (room temperature vulcanizing) silicone adhesive designed for bonding, sealing, and insulating applications that require reliable performance under extreme heat. Unlike conventional adhesives, this formulation not only provides superior thermal resistance but also offers excellent surface protection for metals, ceramics, and composite materials exposed to high operating temperatures.
The adhesive cures at room temperature by reacting with atmospheric moisture to form a flexible, durable elastomer that adheres strongly to a wide variety of substrates. Its heat insulating properties, combined with long-term resistance to weathering, ozone, and UV, make it the go-to solution for demanding industrial and construction environments.
Key Features
High Heat Resistance: Performs consistently in temperatures from -50°C to +250°C, withstanding peaks up to +300°C.
Surface Protection: Forms a protective layer on metal, ceramic, and glass surfaces, preventing oxidation and thermal damage.
Excellent Insulation: Provides both thermal and electrical insulation, ideal for electronics and heat-sensitive systems.
Strong Adhesion: Bonds effectively to metals, ceramics, glass, composites, and some plastics.
Elastic Flexibility: Retains elasticity after curing, absorbing stress from vibration, thermal expansion, and contraction.
Weatherproof: Resistant to aging, UV exposure, ozone, and moisture, ensuring long-lasting outdoor performance.
Neutral Cure Formula: Non-corrosive to sensitive substrates such as aluminum and copper.
Easy to Apply: Single-component, moisture-curing adhesive requires no mixing or heating.

FAQ
Q1: What surfaces can this adhesive bond to?
A1: It bonds strongly to metals (aluminum, steel, copper), ceramics, glass, composites, and certain plastics.
Q2: What makes this adhesive different from standard silicones?
A2: Standard silicones may degrade at high temperatures, while this adhesive is designed for continuous service up to +250°C and short-term peaks of +300°C.
Q3: Can it also protect surfaces, not just bond them?
A3: Yes. In addition to bonding, it forms a protective elastomer layer that shields surfaces from oxidation, corrosion, and thermal damage.
Q4: How long does it take to cure?
A4: Skin formation occurs within 8–15 minutes. Full cure requires 24–48 hours depending on bead thickness and ambient humidity.
Q5: Is it safe for electronic applications?
A5: Yes. It provides both thermal resistance and excellent electrical insulation, making it suitable for electronic assemblies.
Q6: How should it be stored?
A6: Store in a dry, cool environment between 5–25°C. Shelf life is 12 months in unopened containers.
