Den Braven Hybriflex-540 is a professional-grade, low-modulus sealant designed for sealing construction and dilatation joints in various environments. Using innovative hybrid technology, it cures with humidity, forming a durable, elastic rubber that is perfect for absorbing movements between building materials. The sealant is also neutral curing, making it almost odourless and ideal for use in enclosed areas.

This high-performance sealant offers excellent adhesion without primer, even on damp surfaces, and remains permanently elastic. It is free from isocyanates, solvents, and silicones, ensuring a safer application process. With superb resistance to UV, water, and extreme weather, Hybriflex-540 is an ideal choice for long-lasting protection and reliability in a variety of settings.

Den Braven Hybriflex-540 Expansion Joint Benefits and Features:

• Weather-Resistant: Protects against UV exposure, water, and harsh weather, ensuring long-lasting performance.
• Neutral Curing: Virtually odourless and free from isocyanates, solvents, and silicones, offering safer usage.

Applications:

Hybriflex-540 is developed for sealing construction and dilatation joints in pedestrian walkways and other building applications. It adheres to a wide range of materials, including concrete, brickwork, painted wood, aluminium, stainless steel, and various plastics.

Limitations:

• Not suitable for PE, PP, PC, PMMA, PTFE, soft plastics, neoprene, and bituminous substrates.
• Not recommended for glazing joints, natural stone, mirrors, or pool environments (chloride exposure).

Surface Preparations and Finishing:

• Application Temperature: +5°C to +40°C.
• Ensure all substrates are solid, clean, dry, and free of grease or dust before applying the sealant. For porous surfaces, use Universal Primer. Test adhesion before application.

Paintability:

Hybriflex-540 is paintable with water-based and most two-component paints. Synthetic paints may take longer to dry. It is recommended to lightly sand the sealant and adjacent surfaces before painting. For best results, paint within a few days of application.

Cleaning:

• Uncured Material: Clean tools and surfaces with Polyurethane Cleaner.
• Cured Material: Remove mechanically.

Health and Safety Information:

• Precautions: Avoid contact with skin and eyes. Wear protective gloves and safety glasses during application. Keep out of reach of children and pets. Dispose of responsibly.
