Silkoxy H3 (by Everest Systems) is a high-solids, single-component, moisture-curing silicone roof coating designed for long-term protection and restoration of commercial and industrial roofs. It is known for its superior flexibility and ease of application without the need for extensive mixing. 

Key Features

  • Exceptional Flexibility: Offers up to 468% elongation, which is roughly double that of many major competitors, ensuring it won’t crack during building movement.
  • High Solids Content: Contains 90-91% solids by volume, allowing for thick, durable coverage in fewer coats.
  • Energy Efficient: The white version reflects up to 87% of solar heat, potentially reducing roof surface temperatures by up to 80°F.
  • Weather & Water Resistance: Forms a seamless, breathable membrane that withstands ponding water and harsh UV exposure without degrading.
  • Easy Application: Formulated to be less viscous, it can be applied via brush, roller, or high-pressure airless spray. 

Recommended Uses

  • Membrane Protection: Ideal for TPO, PVC, and EPDM roofs.
  • Roof Restoration: Used over weathered metal, primed Cap sheets, and Mod Bit membranes.
  • Internal Gutters: Often used as a proactive repair for internal gutters with good structural integrity. 

Technical Highlights

  • Tensile Strength: ~288 PSI.
  • Tack-Free Time: 20–30 minutes (dependent on temperature/humidity).
  • Full Cure: 48 hours.
  • Temperature Stability: Stable from -80°F to 350°F (-37°C to 177°C).
  • VOC Level: Low VOC (<50 g/L), making it environmentally compliant. 

💡 Pro Tip: For the best results, surfaces must be bone-dry and clean before application to prevent bubbling or adhesion failure
