KE‑13 is a single‑component RTV silicone rubber that cures at room temperature by condensation. It forms a flexible elastomer with strong adhesion to metals, glass, and ceramics. It is moisture resistant and durable, making it suitable for construction, electronics, and industrial sealing tasks.

• Non-Corrosive Cure - KE-13 cures through a neutral condensation mechanism that does not release corrosive by-products during crosslinking. Standard corrosion exposure tests on metals such as copper, aluminum, and carbon steel typically show mass change rates below 0.1 percent after 7 days. This curing behavior supports safe use on metal surfaces and sensitive substrates while maintaining chemical stability after cure.

  
  

• Moisture Resistance - After full cure, KE-13 forms a silicone elastomer with low water absorption characteristics. Typical water uptake remains below 0.5 percent by weight after 24 hours of immersion at room temperature. This low absorption level helps maintain sealing integrity and mechanical stability in humid or moisture-prone environments.

  
  

• Elastic Stability - KE-13 retains elasticity after curing, even under long-term deformation or joint movement. Typical elongation at break exceeds 300 percent, while Shore A hardness generally remains in the range of 20 to 30. These values indicate the cured material can accommodate vibration and displacement without cracking or loss of sealing continuity.

  
  

• Adhesion Strength - KE-13 develops reliable adhesion to common substrates such as glass, ceramics, and metals under standard surface conditions. Typical tensile adhesion strength ranges from 0.6 to 1.0 MPa, supporting stable joint integrity under static loads. This adhesion performance contributes to dependable sealing over extended service periods.

• Construction Sealing - KE-13 is used for sealing joints and gaps in construction assemblies exposed to ambient conditions. Seal thicknesses in the range of 3 to 10 mm can cure evenly under normal temperature and humidity. The cured silicone maintains joint integrity during thermal cycling, supporting long-term durability in building structures.

  
  

• Electronics Protection - In electronics-related sealing tasks, KE-13 is applied to protect components and enclosures from moisture ingress. After curing, silicone layers typically exhibit volume resistivity above 1 × 10¹³ Ω·cm. This electrical stability supports moisture protection for housings, connectors, and non-heat-sensitive electronic assemblies.

  
  

• Automotive Gasketing - KE-13 is suitable for forming elastic gaskets in automotive systems where vibration and temperature variation are present. The cured elastomer typically operates across a service temperature range from approximately −50 °C to 180 °C. This performance range supports reliable sealing in common automotive environments.

  
  

• Industrial Sealing - In general industrial applications, KE-13 is used to seal equipment housings, panels, and mechanical interfaces. Its paste consistency allows controlled application on vertical and horizontal surfaces. Predictable curing behavior supports consistent sealing quality during equipment assembly and maintenance operations.
