High-temperature silicone sealer works on metal, glass, and ceramic with varying degrees of success. Substrate compatibility determines adhesion.

Metal Substrates

Best: Steel, cast iron, aluminum
– Adhesion: Excellent with clean, dry surface
– Prep: Solvent-clean, light sand, dry thoroughly
– Success rate: 95%+

Acceptable: Stainless steel
– Adhesion: Good but requires good prep
– Challenge: Natural oxide layer resists adhesion
– Improvement: Sand lightly; use primer if available

Glass

Silicone bonds well to clean glass.
– Prep: Solvent-clean with acetone
– Success: 90%+ with proper preparation
– Challenge: Silicone can’t bond to oily or dusty glass

Ceramic

Varies by ceramic type.
– Porcelain: Good adhesion (similar to glass)
– Unglazed ceramic: Excellent adhesion (porous surface)
– Glazed ceramic: Fair adhesion (similar to glass)

Key Success Factor

Clean, dry surface is mandatory. Silicone won’t adhere to contaminated surfaces regardless of material.

Real-World Applications

• Metal exhaust: Excellent success
• Glass oven doors: Good success
• Ceramic chimney: Good success
• Galvanized metal: Poor adhesion (primer recommended)

Incure silicone sealers are compatible with steel, glass, and ceramic with proper surface preparation.
