    • Benefits

      • Neutral cure formula – non-corrosive, safe on coated glass and aluminium.  
      • Exceptional adhesion – bonds to a wide range of substrates including reflective glass, stainless steel and powder-coated metals.  
      • Extreme weather resistance – stable from –50 °C to +150 °C, UV and ozone resistant.  
      • Structural glazing approved (ETA 01/0005) – suitable for load-bearing and façade applications.  
      • Black finish – ideal for modern architectural aesthetics where visible joints matter.  

    • How to Apply

      1. Ensure all surfaces are clean, dry and free from dust, grease or old sealant. Prior cleaning using mechanical or solvent wipe is recommended.  
      2. Mask joint edges for neat finish if required.
      3. Apply using a professional sealant gun ensuring continuous positive pressure to fill the joint fully.
      4. Tool immediately for a concave finish and remove masking tape while the sealant is still wet.  
      5. Allow to cure – this product is generally factory applied for optimum results; on-site application should follow manufacturer guidelines.
