You need a bond that holds on contact. A sealant that moves with the structure. A single product for multiple materials, even damp ones, without waiting for mechanical support. Hi-Power 609 delivers that immediate grip, securing heavy panels or complex assemblies in seconds. It is the 600ml solution for high-volume jobs where speed, strength, and flexibility are non-negotiable.

Why this product exists

This product is an elastomeric MS hybrid polymer adhesive/sealant engineered for immediate grab and high-end strength. It handles diverse bonding and sealing applications across building, industrial, sign, display, vehicular, caravan, and marine sectors. Formulated as a 600ml sausage, Hi-Power 609 is designed for high-volume application via pneumatic, cordless, or hand gun, making it efficient for large projects. It ensures elastic bonding for components subject to vibration or deformation, and allows vertical application of heavy materials without extensive temporary support, even on damp surfaces.

The numbers that matter

  • 1-second immediate grab: Reduces the need for temporary bracing or mechanical support, especially on vertical applications. This saves time and simplifies installation on site.
  • Wet strength up to 400 kg/m²: Provides substantial initial holding power, allowing you to position and secure heavy elements directly. For the heaviest items, temporary mechanical support may still be required until full cure.
  • Shore A 50 hardness after 14 days: Delivers a durable, resilient bond capable of withstanding operational stresses and impacts. This balanced hardness contributes to the product's long-term performance as both an adhesive and a sealant.
  • Elongation at break of 200%: Ensures permanent flexibility, absorbing constant vibration, shock, and structural movement without failure. This is critical for applications in vehicles, caravans, or dynamic building structures.
  • VOC 38 grams per litre: Complies with low VOC "Green Star" environmental criteria, providing a low odour, non-toxic solution for indoor and outdoor applications.

What it's like to use

Apply Hi-Power 609 at temperatures between 5°C to 40°C. Load the 600ml sausage into your pneumatic, cordless, or hand gun. Use a triangular nozzle, holding the gun at a 90° angle, dispensing the adhesive behind the nozzle. Ensure a triangular bead at least 2mm thick for optimal elastic performance. For non-porous surfaces like aluminium or powder-coated metals, clean and pre-treat with Adheseal 50A Surface Prep. For porous substrates such as concrete or cement-based renders, prime with Everflex Supaprime Sealant Primer. Allow 30 minutes to 2 hours for primers to flash off before applying the adhesive.

The product skins in 10 to 30 minutes and cures at approximately 2mm per 24 hours at 25°C and 50% humidity. Cure times vary with atmospheric conditions and substrate porosity, as atmospheric humidity is required for curing. While wet, clean tools and spills with white spirit. Cured product requires mechanical removal.

Where this product excels

  • Building & Construction: Bond wall panels, splashbacks, and cladding. Its instant grab eliminates the need for most bracing, providing a clean, fastener-free finish. Use it for skirting, architraves, and other general construction bonding where versatile adhesion to damp surfaces is an advantage.
  • Signage & Display: Securely mount signage, displays, and fixtures. Its high strength and UV resistance create a durable, weatherproof bond on multiple substrates, suitable for both indoor and outdoor installations.
  • Caravan, Marine & Vehicular: Use for elastic structural bonding in vehicles, caravans, and marine applications. The permanent flexibility absorbs constant vibration and shock without material failure, maintaining integrity in dynamic environments.

Choose this when

  • You need an adhesive with immediate holding power for vertical or overhead applications, reducing the need for temporary mechanical support.
  • Your project demands high-volume application in a 600ml sausage format, compatible with pneumatic, cordless, or hand guns.
  • Bonding or sealing is required on diverse materials, including slightly damp surfaces, without compromising adhesion strength.
  • The application involves materials subject to vibration, deformation, or structural movement, requiring a permanently elastic bond.
  • You need a low VOC, low odour solution for both internal and external bonding and sealing.

Don't use this when

  • Not for: Totally confined or closed spaces. This product requires atmospheric humidity to cure and will not perform where air access is limited.
  • Not for: Structural glazing. For these critical applications, use N-80 or N-60 Glazing silicone.
  • Not for: Contact with bitumen, tar, or plasticizer-releasing materials such as EPDM, neoprene, or butyl. This can cause discolouration and loss of adhesion.
  • Not for: Aquariums or direct contact with copper and brass. The sealant may discolour these materials.

Hi-Power 609 meets low VOC (Volatile Organic Compound) "Green Star" environmental criteria, containing only 38 grams per litre. This ensures a low odour, non-toxic solution, contributing to healthier indoor air quality and compliance with environmental standards on construction projects.
