Description  
Use Hi-Flex Construction for: Perimeter sealing of windows, expansion joints in precast panels, and general construction sealing.

Hi-Flex Construction is a single-component, elastomeric joint sealant based on MS Polymer technology. It delivers exceptional flexibility with a 50% movement capability, making it ideal for dynamic joints. Its neutral cure formula ensures compatibility with a wide range of substrates, including metals, concrete, and timber. With excellent UV and weathering resistance, it's suitable for both internal and external applications, providing a long-lasting, resilient seal.

Key Features of Hi-Flex Construction

  • High Movement Capability: Accommodates up to 50% movement, preventing joint failures in dynamic structures.
  • Excellent UV and Weathering Resistance: Maintains performance and appearance in harsh Australian climates, reducing maintenance needs.
  • Primer-less Adhesion: Bonds strongly to most non-porous substrates, simplifying application and saving time.
  • Paintable: Compatible with acrylic, oil, and rubber-based paints, allowing for seamless integration into various finishes (test adhesion first).
  • Mould and Mildew Resistance: Inhibits biological growth, making it suitable for humid environments and ensuring long-term hygiene.

Technical Overview

Hi-Flex Construction is engineered for high performance in demanding construction environments. Its low modulus and high elasticity provide a durable, flexible seal that withstands structural movements and environmental stresses. This MS Polymer sealant cures to form a permanently elastic joint, ensuring long-term performance and reliability.

Chemical Properties: MS Polymer, offering neutral cure and excellent chemical resistance to water and dilute chemicals.

Application Temperature Range: 5°C to 40°C (41°F to 104°F), ensuring usability in a wide range of ambient conditions. Optimal application ensures proper curing and adhesion.

Application Information

  • Required Tools: Sausage gun, caulking gun, spatula, masking tape, Xylene for cleaning.
  • Trade-Specific Tips: Use a backing rod to control joint depth and prevent three-sided adhesion. Ensure surfaces are clean and dry for optimal bonding. For non-porous surfaces use Adheseal 50A surface prep.
  • Common Issues and Solutions: Bubbling can occur from entrapped air; ensure proper tooling and avoid over-application. Discoloration may happen with incompatible substrates; always perform a test patch.

Storage and Shelf Life

  • Storage Requirements: Store in a cool, dry place away from direct sunlight.
  • Shelf Life Information: 12 months from the date of production.
  • Temperature Considerations: Avoid extreme temperatures during storage to maintain product integrity.

Certifications

  • ASTM C920-CLASS 50: Demonstrates high movement capability and durability.
  • ASTM C1248: Ensures non-staining properties and compatibility with various substrates.
Common Questions  

Frequently Asked Questions About Hi-Flex Construction

Q: What is the best way to apply Hi-Flex Construction?

A: For sealant applications, cut the nozzle at a 45-degree angle. For adhesive applications, cut at 90 degrees. Ensure surfaces are clean and dry, and use a backing rod for proper joint depth. Tool the sealant before it skins over, typically within 10 minutes.

Q: How does Hi-Flex Construction perform in extreme weather?

A: Hi-Flex Construction offers excellent UV and weathering resistance, maintaining its elasticity and adhesion in a wide range of temperatures (-40°C to 100°C). Its high movement capability accommodates thermal expansion and contraction, ensuring long-term durability.

Q: Is Hi-Flex Construction compatible with all building materials?

A: It adheres well to most common building materials, including concrete, metals, and timber. However, certain materials like copper, brass, and some plastics may require testing. Always conduct a preliminary adhesion test for optimal results.

Q: What are the key technical properties of Hi-Flex Construction?

A: Key properties include a movement capability of ±50%, elongation at break of 1100%, and a Shore A hardness of 25. It also boasts excellent UV resistance and a neutral curing system, ensuring strong, flexible bonds.

Q: What safety precautions should I take when using Hi-Flex Construction?

A: Wear appropriate PPE, including gloves and safety glasses. Ensure adequate ventilation during application. Clean tools and spills with Xylene while the product is wet. If cured, use mechanical means. Always refer to the SDS for detailed safety information.

Uses & Benefits  

Use Hi-Flex Construction for:

  • Perimeter Sealing of Windows: Provides a flexible, weather-resistant seal around window frames.
  • Expansion Joints in Precast Panels: Accommodates movement in large concrete panels, preventing cracks.
  • Sealing and Finishing External Wall & Cladding Joints: Ensures a durable, waterproof seal in facade systems.
  • Adhesive for Lightweight Components: Bonds acoustic ceiling tiles, display signs, and other light materials.
  • Automotive and Marine Applications: Ideal for bonding and sealing in vehicle and boat manufacturing.

Why Use Hi-Flex Construction:

  • High Flexibility: Accommodates significant joint movement, preventing failures in dynamic structures, like expansion joints in buildings.
  • Excellent Adhesion: Bonds strongly to various substrates without priming, saving time and effort on projects, such as metal cladding installations.
  • Weather Resistance: Maintains performance in harsh Australian climates, ensuring long-term durability for external applications, such as window sealing.
  • Mould Resistance: Inhibits biological growth, making it suitable for humid environments, like bathrooms and kitchens.
How To Apply  

How to apply Hi-Flex Construction:

  1. Prepare the Surface: Ensure surfaces are clean, dry, and free from contaminants. Use Xylene for cleaning impervious surfaces.
  2. Prime if Necessary: For porous surfaces, use Everflex Supaprime. For non-porous surfaces, use Adheseal 50A surface prep.
  3. Apply the Sealant: Cut the nozzle to the desired angle and apply a continuous bead, ensuring complete joint filling.
  4. Tool the Sealant: Use a moistened spatula to smooth the sealant before it skins over.
  5. Clean Up: Remove excess sealant with Xylene while wet. Once cured, use mechanical means.
Limitations and Safety Info  

Limitations

  • Not suitable for long-term water immersion or swimming pools
  • Cannot be used in totally confined spaces due to the need for humidity curing
  • Avoid use with chlorine exposure or in aquarium applications
  • Not recommended for structural glazing or mirror bonding
  • May cause discolouration on copper and brass surfaces
  • Avoid using on bituminous surfaces or where compounds may leach solvents
Suitable Substrates  

Hi-Flex Construction can be used on the following substrates:

  • Concrete and Masonry: Including precast and tilt-up panels, with proper surface preparation.
  • Metals (excluding lead and copper): Such as aluminium, stainless steel, and powder-coated metals, often without priming.
  • Timber: Suitable for various wood types, providing a flexible and durable seal.
  • Plastics: Including PVC and fibreglass, though a preliminary adhesion test is recommended.
  • Painted Surfaces: Compatible with acrylic, oil, and rubber-based paints (test adhesion first).
