Airlok® STPE Detail-N-Joint

Airlok® STPE Detail-N-Joint is a single-component, cold-applied, Silyl Terminated Polyether (STPE), fiber-filled, fluid joint filler and transition flashing material; that combines the best of silicone and polyurethane properties. Typical detailing application includes Sheathing joints, penetrations and filling in imperfections on surfaces such as concrete walls and wood window bucks.

FEATURES & BENEFITS

  • Versatile detail compound for application at transitions and flashing
  • Can be used on damp or wet surfaces
  • Unlike silicone products, Airlok® STPE Detail-N-Joint is compatible with virtually all common building materials
  • Existing cured membranes readily receive additional application creating a monolithic transition
  • Wide range of application temperatures from 25°F (-4°C) up to 110°F (44°C)
  • Resistant to wash-off during rain events, extending the application time relative to inclement weather
  • High solids content of 100% for high yield and <20 g/l VOC
  • Compatible with most known building materials
  • Long term exposure to the sun’s ultra violet (UV) rays for a period up to nine (9) months
  • Long term physical durability and chemical stability as a liquid applied air barrier system
  • Compliant with NFPA 285 in most wall assemblies
