When the joint needs to hold, even under abuse. When components require a robust bond without the added step of priming. Hi-Flex 60 is engineered to deliver a secure, durable seal and adhesive bond across diverse applications. It stands up to picking and offers reliable performance where lesser sealants fail.
Hi-Flex 60 is a high modulus (Shore A 55) MS Polymer-based hybrid adhesive/sealant developed for robust bonding and sealing in demanding environments. It addresses the need for anti-pick performance in public areas like schools, prisons, and other high-traffic spaces, where sealant integrity is critical. This formulation also provides outstanding primer-less adhesion on non-porous substrates, simplifying application and reducing failure points caused by missed priming. Free from isocyanates, solvents, and acids, it offers a safer profile for users and prevents compatibility issues with sensitive materials. Hi-Flex 60 ensures long-term durability, preventing common failures such as sealant degradation, adhesion loss, and premature cracking, even when components have different thermal expansion rates.
Hi-Flex 60 is designed for user-friendly application, with easy gunning and tooling. Tool the sealant within approximately 10 minutes of application to achieve a smooth finish before it skins over. The product cures at a rate of 3mm per 24 hours under standard atmospheric conditions (25°C and 50% humidity), ensuring a durable, flexible seal. For wet clean-up of tools and spills, use Xylene. For skin clean-up, Adheseal Hand Wipes are recommended. For optimal adhesion on porous substrates like concrete or brick, prime surfaces with Everflex Supaprime Sealant Primer. On critical non-porous surfaces, use Adheseal 50A Surface Prep after mechanical abrasion to enhance bond strength. For joint depth control and to prevent three-sided adhesion, use a compatible Adheseal backer rod.
Hi-Flex 60 serves as a critical final seal or adhesive bond in various construction and manufacturing assemblies. After thorough surface preparation, apply the sealant into the joint, often over a compatible backer rod for optimal depth and two-sided adhesion. For non-porous substrates that require enhanced bond strength, apply Adheseal 50A Surface Prep prior to sealant application. On porous surfaces, use Everflex Supaprime Sealant Primer to promote adhesion and ensure long-term joint integrity.
Hi-Flex 60 is distinguished by its high Shore A 55 modulus and anti-pick performance, making it the clear choice for demanding public areas and specific structural bonding tasks like XPS foam panels. While both are MS Polymer hybrids, Adheseal Hi-Flex 50 Low-Modulus Waterproofing Membrane is designed for a higher movement capability (+/-35%) and excels as a versatile, low modulus sealant suitable for general construction, waterproofing membranes, and bond breaker applications. Choose Hi-Flex 60 when you need a stiffer, more resilient seal and bond, particularly where physical abuse or specific panel bonding is a concern, and Hi-Flex 50 for more dynamic, higher movement joints or as a general-purpose waterproofing sealant.
Hi-Flex 60 has a Shore A hardness of 55, classifying it as a high modulus sealant. This firm, resilient cure makes it suitable for anti-pick applications in public areas like schools or prisons.
No, Hi-Flex 60 is non-staining as per ASTM C510 and ASTM C1248 standards. This prevents discolouration on most common building materials, though a stain test is always recommended for natural stone.
Hi-Flex 60 offers a movement capability of +/-25% as tested to ASTM C719. This allows it to accommodate significant joint movement without cracking or losing adhesion, ensuring long-term flexibility in dynamic applications.
No, Hi-Flex 60 is not suitable for long-term water immersion or internal swimming pool applications. It is also not recommended for aquariums or totally confined spaces, as atmospheric humidity is required for proper curing.
| Application | Key benefit | Primary trades |
|---|---|---|
| XPS Foam Core Reinforced sandwich panel bonding | Outstanding primer-less adhesion on non-porous substrates, ensuring strong bonds for lightweight panels. | Prefabricated builders, commercial builders |
| Sealing joints in prefabricated buildings and concrete panels | +/-25% movement capability maintains a flexible, waterproof seal in high-movement construction. | Concrete contractors, commercial builders |
| Anti-pick sealant for schools, prisons, public areas | High modulus (Shore A 55) provides a tough, resilient seal that resists picking and vandalism. | Government contractors, facility managers |
| Aluminium fabrication and general construction component adhesion | Non-corrosive formulation and primer-less adhesion to metals, timber, and plastics, simplifying diverse material bonding. | Aluminium fabricators, general builders |
| Automotive and marine manufacturing bonding and sealing | Excellent UV and weathering resistance ensures long-term durability in harsh outdoor environments. | Automotive fabricators, marine manufacturers |
Wear gloves (Nitrile Rubber is suggested for intermittent contact) and safety glasses.
Natural ventilation is adequate under normal use conditions.
Store in a cool, dry, well-ventilated area away from direct sunlight, foodstuffs, incompatible materials, and ignition sources. Keep containers upright and closed. Dispose of according to state or local regulations.
Proper surface preparation and priming are critical for achieving optimal adhesion and long-term performance across various construction materials.
Surface prep: All surfaces must be stable, dry, clean, and free of dust, loose material, oils, grease, or any contamination that may hinder adhesion. Concrete requires at least 28 days of cure. For impervious substrates, use a two-wipe process with Xylene, changing cloths frequently.
Primer: Often not required due to Hi-Flex 60's high bond strength. However, for critical applications like multi-story buildings, highly stressed joints, extreme weather exposure, or potential water immersion, specific priming is recommended.
Surface prep: Slightly roughen surfaces like aluminium, anodized aluminium, stainless steel, PVC, galvanised steel, powder coated metals, or glazed tiles with a fine abrasive pad. Clean thoroughly.
Primer: Optional. For optimal adhesion, pre-treat with Adheseal 50A surface prep using a clean cloth. Apply sealant between 30 minutes and 2 hours after priming. Adhesion tests are advised for copper, brass, titanium-zinc, and PVC.
Surface prep: Ensure concrete, aerated concrete, cement-based renders, mortars, and bricks are sound, dry, and clean.
Primer: Required for optimal adhesion in critical applications. Prime surfaces using Everflex Supaprime applied by brush. Apply sealant between 30 minutes and 2 hours after priming.
